Abstract
Purpose
The COVID-19 pandemic has affected orthopedic practices worldwide. Few studies focusing on epidemiology and management of fractures in COVID-19 patients have been published. We conducted a systematic review to evaluate the fracture types, presentation, treatment, complications, and early outcomes of fractures occurring amidst COVID-19 pandemic.
Methods
A systematic review of the all published papers was conducted with a comprehensive search of PubMed, Google Scholar, Scopus, and Cochrane Library database using keywords ‘COVID-19’, ‘Coronavirus’, ‘trauma∗’and ‘fracture’ from January–April 2020.
Results
The searches yielded a total of ten studies with 112 Patients who were positive for COVID-19 associated with fractures was performed for six studies, reporting data separately for 44 patients with COVID 19 and an associated fracture. A diagnosis of COVID 19 was made on the basis of positive Computed Tomography scan in 39 patients and 30 patients had a positive Reverse Transcription-Polymerase Chain Reaction test. Overall, there were 29 proximal femoral fractures, 8 spine fractures, 7 fractures of the other bones. The fractures were treated surgically in 30 cases (68.18%) and the remaining 14 cases (31.82%) were managed conservatively. There were 16 patients (36.36%) who died, mostly due to respiratory failure with a median age of 82 years.
Conclusion
COVID-19 has led to a significant reduction in a load of fracture patients globally, though the incidence of fragility fractures continues to be unaffected. There is a significantly higher risk of mortality in elderly patients with fractures and hence they should only be operated in a facility with a robust intensive care. Conservative treatment should be adopted as far as possible in non-obligatory fractures and in lesser equipped centers. Surgery in patients with proximal femur fragility fractures when judiciously selected did result in improvement in respiratory status. Reorganizing medical services is vital to deliver effective fracture care and also mitigate disease transmission.

1. Introduction
The novel coronavirus disease – 2019 (COVID-19), has significantly affected trauma services globally. Though the motor vehicle accidents (MVA) have drastically reduced due to extensive lockdown, still the patients with low energy and fragility fractures are seeking treatment in emergency. Till date, only a few case reports or series with a small number of patients with fractures have been published in the literature.1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23 Hence, the information from one study may not give clear guidance to fracture treatment during COVID 19 pandemic. In many countries the surgeons have not started doing surgeries for various fractures despite various available guidelines due to lack of resources, experience to treat such patients, limited access to negative pressure operation theatres, and COVID related anxiety. We have performed a systematic review of the available studies, by analyzing the fracture types, presentation, treatment, complication, and early outcomes among COVID-19 negative and positive patients. We aim to provide more insight into how the fracture treatment can be improvised, adapted, or innovated so as to provide a quality fracture care, similar to the pre-COVID era without harming the patients and health care workers.
2. Method
We have performed a systematic search of the following electronic databases: PubMed, Google Scholar, Scopus, Cochrane Library, and Web of Science. We used keywords and boolean operators (‘COVID-19′ OR ‘Coronavirus’) AND (‘trauma∗’ OR ‘fracture’) on PubMed and similar searches were performed on other databases from 1st January to April 30, 2020, to identify relevant articles reporting fractures during COVID 19 pandemic. Relevant articles reporting data on fractures in the form of case series, case-control, and cohort studies were included. Articles related to non-orthopedic injuries were excluded. Reference lists of articles were also screened for more relevant papers and we also hand-searched popular premier orthopedic journals (JBJS, BJJ, CORR, INJURY, ABJS, Acta Orthopaedica, IJO) and general medical journals (JAMA, NEJM, Lancet) to avoid missing any paper. Studies were excluded if it did not report fractures. We also included relevant editorials, opinions, and reviews for qualitative summarization.
Statistical analysis: The descriptive data regarding patient characteristics available from all studies were summarized in tabulated form. Study quality of individual studies reporting data on all csaes was ascertained using the methodological quality assessment tool proposed by Murad et al. for case reports and case series.23 (Table 1) Overall mean and standard deviation/median (range) were used to summarize the data for continuous variables and frequency/percentage for categorical variables and appropriate graphics were used for data depiction. Microsoft Excel version 2016 (Windows) was used for analysis.

3. Results
The search yielded a total of 180 articles on PubMed, 122 on Scopus, and one on Cochrane library. Hand search revealed 6 more papers, and 5 relevant papers were revealed on Google Scholar search. After screening duplicates and excluding irrelevant articles based on the title, twenty relevant papers were considered and a total of ten studies with 112 Patients who were positive for COVID 19 and had suffered a fracture were finally included for analysis after full-text assessment. (Fig. 1, Prisma flowchart). Summarisation of data was performed for six studies, reporting data separately for 44 patients with COVID 19 and an associated fracture. Apart from this, in the study by Vibes JMM et al., there were 136 (102 Female, 24 Male; 123 survived and 13 died) patients, among whom 23 were PCR positive for COVID 19, and seven had expired among them, but the PCR test was not done in 74 cases due to low suspicion. All IPD was not reported. Characteristic features of each study have been summarized in Appendix 1 file.

Patient demographics: Among the 44 patients, the median age was 79 years with a range (14 years–93 years). The mean age was 67 years with SD of 22.92. There were 24 males and 20 females (Fig. 2A).
Fig. 2.
Age distribution boxplot (A); Comorbidities seen in fractures cases with COVID 19 (B); Fractures encountered in COVID 19 cases (C).
Diagnosis of COVID 19: Diagnosis of COVID 19 was made on the basis of positive Computed Tomography (CT) scan findings in 39 patients, and 30 patients had a positive Reverse Transcription-Polymerase Chain Reaction (RT-PCR) test report. Both tests were positive in 16 patients. RT-PCR had limited availability at several centers initially, so characteristic chest CT findings were used for COVID-19 diagnosis initially in most of the cases. Either of these tests (RT-PCR or CT Scan) were positive in all the cases mentioned.
Comorbidities: Fifteen patients (34.09%) had hypertension and seven were suffering from a cardiac disease (15.90%). Five patients had both hypertension and cardiac disease (11.36%). Ten patients (22.72%) had type 2 diabetes mellitus. Three diabetics; had cardiac disease. Six patients had both diabetes and hypertension, and two such patients had all these three comorbidities (Fig. 2B).
We focused on these comorbidities because these have been reported as risk factors for mortality in COVID 19 patients in the earlier studies.24 Obesity and Chronic Obstructive Pulmonary Disease (COPD) were also considered as a risk factor for mortality, but we could not analyze it as it was not reported, in the most included studies.
Fractures: Overall, there were 29 proximal femoral fractures, six thoracolumbar fractures, two cervical spine injuries, and only seven fractures of the other limb bones (Fig. 2C).
Surgery and conservative care: The fractures were treated surgically in 30 cases (68.18%) and the remaining 14 cases (31.82%) were managed conservatively. The exact type of surgery has not been explicitly mentioned by most authors, but in general, it was guided by the fracture pattern, patient comorbidity, and medical fitness. For cases with hip fractures, hemiarthroplasty (five cases) or intramedullary fixation (eight cases) has been mentioned by Catellani F et al.,12 whereas Chehdrassan M et al.6 managed two cases with spine fractures conservatively and five underwent decompression and instrumented fusion.
Treatment of COVID-19: Oxygen therapy with a Venturi mask was used in most of the cases, and ventilators were also used when necessary, although complete data has not been provided by all the authors. Details regarding antiviral therapy were available in all six manuscripts and as per the available data (HCQS alone-2 cases, HCQS + Oseltamivir- 5 cases, HCQSDr + Azithro-17 cases, Oseltamivir alone-11 cases, HCQS + lopinavir + ritonavir-1 case and HCQS + Azithromycin + Oseltamivir-1 case) the usage pattern has been depicted in (Fig. 3).

3.1. Mortality of patients
There were 16 patients (36.36%) who died, mostly due to respiratory failure and one case had massive hematuria. The median age (range) of these patients was 82 (27–93) years, whereas their mean age was 76.19 years (with an SD of 17.96). These were eight males and eight females. (Separate individual patient data for the seven COVID-19 RT PCR positive fracture patients, who had expired, was provided by Vibes et al.11 If we consider them as well, there were 23 patients (52.27%) who experienced mortality. Among them, the median age (range) was 85 (27–100) years and their mean age was 80.78 years (with SD of 16.65). These were 11 males and 12 females) (Fig. 4 and Fig. 5). Nunez AH et al.17 reported only 13 patients (0.52%) with confirmed COVID-19 (7 patients confirmed at admission and 6 diagnosed post-operatively) among 2495 (512 in the lockdown period from 14th March to 2nd April and 1983 cases in the preceding 20 days) cases of trauma visits in the COVID-19 season, at a tertiary care center in Spain. Three cases (23.07%) expired prior to undergoing surgery, one after surgery (7.69%), four were discharged home (30.76%), and five remained admitted in the hospital for which further details were not available. Similarly, 7 Sadighi et al.20 have reported one death (7.69%) in their 13 fracture patients with COVID-19. But, Maniscalo et al.19 reported a high mortality rate of (43.75%) in their 32 COVID cases with proximal femoral fractures, from Italy. The main cause of death was cardiac arrest (4 cases, 44.4%), multiple organ failure (3 cases, 33.3%), septic shock (1 case, 11.1%) and renal failure (1 case, 11.1%) among the 9 deaths reported from Piacenza. Among the five COVID positive deaths reported from Parma, causes were cardio-respiratory arrest (4 cases, 66.7%) and septic shock (1 case, 16.7%). Among these patients, RT-PCR for COVID 19 was positive in 12 cases before death, it came positive after death in one case. In the rest, the diagnosis was based on positive CT chest findings. There were 3 patients with hypertension, 1 with cardiac disease and 4 with diabetes type 2. It is important to note that only one case had both heart disease and diabetes.

Hip fractures were predominant in patients suffering mortality; 13 cases (29.54%) had proximal femoral fractures, whereas there was only one case of cervical spine injury and two dorsolumbar fractures. Ten patients were surgically managed and six were treated conservatively. Seven of these patients were receiving Hydroxychloroquine- Azithromycin combination, five were receiving Oseltamivir alone and one each was receiving Hydroxychloroquine with Oseltamivir combination, and Lopinavir-Ritonavir-Hydroxychloroquine combination. More mortality was experienced among those with higher age (Fig. 5). Most papers related to fractures and COVID-19 came from Iran (4), followed by Italy (3), China (3), and the USA (3) (Fig. 6A). In our study, the maximum number of patients were from Iran (17), followed closely by Italy (16), and China (10) (Fig. 6B).

4. Discussion
This study was designed to reflect on how the COVID-19 pandemic has affected fracture care globally, with a propensity to some fractures over other, the surgeon’s treatment selection mode, preoperative investigations done, the surgeon and patient protective measures taken, the remodeling or modification of the operating theatres, hospital stay, antibiotic pattern, and general complications peculiar to COVID 19, morbidity and mortality. In this study, we aimed to assess also the prevalence of accompanying comorbidities in fracture patients tested positive for COVID-19. The main points investigated in this review have been summarized in Table 3.
Table 3.
Recommendations on various parameters for COVID1-19 patients based on evidence based literature.
| Question | Recommendations based on evidences | |
|---|---|---|
| Did countries segregate COVID patients needing fracture care from non-COVID at entry into a health care facility or did they have different COVID and non-COVID areas in a health center? What was the PPE used? | Majority had, and it’s better to have different COVID and non COVID health care facilities. If not possible; make a separated contaminated and sterile corridors in a health center (separate OPD, wards, OT, pharmacy) to decrease nosocomial infections. Separate isolation wards in emergency are a must till patient’s COVID clearance.5, 6, 7,11, 12, 13 | |
| Did this review consider only emergency trauma surgeries? | Fracture care in emergency was mostly available and was researched.1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 | |
| What major changes have occurred in the epidemiology of fractures in the COVID 19 era? | Overall fracture incidence has decreased but new types of injuries were also seen.14,17,19 Contingency plans in these times need to be targeted for osteoporotic hip fractures. |
|
| Were the patients triaged? Was there any screening protocol followed in case of emergency? Should all in patients be screened and sampled? How is OT-emergency zoned. How many initially asymptomatic cases were there? |
Two types of triaging needs to be done one for emergency trauma by ATLS, SHiFT scores etc.7 and other is on basis of COVID status. There is consensus that all admitted patients should be screened clinically into covid positive, covid suspects (clinically & pandemic zones >100/100,000 resident) and clinically covid negative at ER gate for direction to clean covid free pathways and nonclean/covid facility or zones for clearance by covid swab for RT-PCR and/or CT. BUT Operate emergency cases with universal precautions and less emergency cases after RT-PCR or CT chest scan (experienced radiologist) report.1,5,6,12,15,17 |
|
| Were clinical symptoms of COVID different? What were the common modes of injury? |
No Fragility fractures were seen most often.4,6,12,15,16 |
|
| Which blood parameters were altered commonly and which were peculiar to trauma in covid? | Leucocytosis (neutrophilic) with raised CRP is common. Lymphopenia and raised D dimer were more common in fractures. LDH &D dimer are prognostic factors4,6,12,13 | |
| What about sensitivity of HRCT/Chest CT and RT-PCR, should both be done, do they complement each other? Which is a better screening tool in an emergency setting? Do they prognosticate? | CT Chest though has increased radiation risk is a fast screening tool with high sensitivity in emergency settings, and is also a prognosticating tool. RT-PCR is specific, needs to be done in all and has important role in patients with equivocal CT. False positive and false negative should be avoided- use both.6,12,13,and 15 | |
| Is orthopedic regional triaging beneficial? | A separate spine center/unit if developed the authors feel would reduce surgical time.1,6,8 | |
| When should COVID testing be done in preoperative period? | If a patient has been tested in last seven days repeat test is not required, It’s better to do RT-PCR test 24–72 h before surgery in new patient.1,18 | |
| Did hospitals have outpatient-fracture clinics? How to optimize fracture care visits | It is better to have a fracture clinic with a dedicated x-ray room so that conservatively treated patients can be managed separately and swiftly. Mild cases can be sent home and followed up via telemedicine. Screening and social distancing to be practiced9 | |
| Were more and more fractures treated conservatively? Was skeletal traction a mode of treatment used? | Tendency of treating fractures conservatively was more. (Mildly displaced intra articular fracture distal radius) Patients who were sick/associated serious systemic problems should be managed conservatively.4,13 | |
| Which fracture is emergency and to be operated first? Any objective tool? What was the time from presentation to surgery? |
It is upto the health authorities do a risk assessment and determine whether the patient’s surgery can be postponed until COVID results return negative or positive patients are no longer infectious and if the situation is an emergency.5 The tier system, ACS and IOA recommendations and SHIFT tools do guide us in making this decision.5 Unnecessary procedures for spine trauma patients should be avoided in order to reduce complications related to surgery and to preserve ICU beds.6 surgery be done for emergent or urgent cases, that is fractures truly requiring operative fixation to avoid mortality or significant morbidity due to a delay of greater than 30 days”.9 All open fractures, hemodynamically unstable fractures, proximal femoral fragility fractures, spine fractures with increasing neurological deficit, cauda equina syndrome should be considered for urgent surgery. If fracture surgery can be delayed for 30 days without disability and life/limb risk it should be.9 |
|
| Is proximal femoral fracture an emergency for surgery. Is surgery beneficial and what is the best |
Yes, unless patient is unfit for surgery (PO2,temperature, SHiFT tool may act as guides).8In principle, active surgical treatment should be performed unless the patient’s health condition is very poor, the patient cannot tolerate the operation, the risk of death during the operation is very high or postoperative nursing would be very difficult It improved O2 saturation and assisted respiratory support4,8,12,15,17,19,21 Dictum: Operate within 24 h reduce blood loss and early respiratory rehab to avoid ICU.12 |
|
| Is spine fracture an emergency? How to proceed after primary survey and immobilization? |
Spine fractures with increasing deficit, incomplete deficit, cauda equina syndrome in unstable fracture, or cervical fractures should be operated but All Non urgent spine surgery should be stopped or should be planned for non lockdown after critical assessment, as it carries more risk of pneumonia.11,18 TIMELINE:
|
|
| What cases did anaesthetist refuse (risky/red flags) or were there some systemic indicators that dictate against surgery? | Each facility can develop their own recommendations but pO2, ASA grades and temperature should be a part of all criteria.11 | |
| Was there any special PAC advise or preoperative advice? Antiviral and chemotherapy-what and when to start -preop or postop? |
It is agreed upon that all antiviral, hydroxychloroquine and oxygen support should be started as soon as possible in fracture with COVID. Steroids can be used in spine, head injury with deficit though not recommended due to its impairing effect on immune system3,4,6,8,11, 12, 13, 14, 15, 16 | |
| Were fractures due to fall more common for the reason of febrile patient’s general or systemic weakness? Was there a need for health education by media? Were any new fracture patterns seen? | Yes, may be due to febrile fatigue fractures can occur due to fall. Health education in preventing falls will reduce16 number of osteoporotic hip fracture. The panic, depression, or irritability during the epidemic/lockdown period is also a topic that needs to be counselled15,16 | |
| What was the influence on fracture care of associated systemic injuries? | Thus, the decision was based on individual patient considerations, and was surgeon based, though more inclined towards conservative treatment for fractures.4,6,13 | |
| Was the OT setup different or it required change/refurbishing for COVID with fracture Airflow, negative suction and zoning |
COVID and non COVID facility to be separate and OT to be zoned according to sterility and utility, Negative suction and air changes are essential for treating COVID with fracture. Isolation areas to be setup separately. Postop HDU to have less and only needy patients, daily assessment for speedy turnover. HEPA filter and AC of closed type as per norm.4,5,11,16 | |
| How much interval time should be there between operative cases or breathing space for OT between cases;How many OT were used at a time | There should be 30 min wait after surgery for aerosol to settle before deep cleaning of OT is started. All agree on breathing time for OT though vary from 1 to 4 h for sanitization and cleaning. Zoning of OT a must. (donning in area,a sterile passage and doffing area).Air exchangers to function before anyone who has no respirator protection enters the room and before environment cleaning.11, 22 | |
| What was the details of PPE kit used in OT. How many persons should be there in OT | In Emergency/unknown/unconscious unstable patients complete PPE should be used by surgeon &anaesthetist (positive pressure hood, water repellant gowns n95 respirators, face shields and antiviral latex disposable gloves). Covid negative: anesthesia given complete ppe and rest n95, latex gloves, hood and standard precautions (as may be in window period); Minimize the number of person in the OR. Maximum of 8 people to should be there for any procedure, including anesthesia, surgical team, nursing and technicians.2,4,5,8 |
|
| What is the type of anesthesia used/preferred: | Regional anesthesia preferred unless as in indicated. Blood loss was minimized by avoiding fluid overload and managing patients who had hemoglobin values of <F9 g/dL with concentrated red blood-cell transfusion.12,15,16 | |
| What were the instructions to surgical team during administration of anesthesia | Surgeons should stay out of the operation room during induction, intubation or extubation of anesthesia procedure5,8 | |
| What was criteria of selection of Implants type used or were they same: | There were no special recommendations. The authors suggest that to decrease AGP hand drill and hand reamers with frequent stop and closed suction, self-drilling self-tapping screws, unreamed nails, swift MIPPO technique and use K wire where possible.8,12 | |
| Was minimally invasive surgery preferred | It’s preferred if you have or are proficient at it but don’t be adamant on doing minimally invasive as decreasing surgical time is essence (decrease AGP).6,16 | |
| How to decrease aerosol -virus and is it transmitted by blood in surgery | Hand tools may be preferred as aforesaid though decreasing surgical time is essence so use electrosurgical instrument at least power and with closed suction. For use of Drain - No change5,9,14 | |
| What were the type of sutures preferred | Resorbable self-locking sutures, transparent dressings. Teleservices/instruction video for self or nearby care provider removes sutures.5,9 | |
| Has the surgical time increased for fractures with COVID | The surgical time should be minimized - avoid experiments during surgeries, a well-known approach or procedure to the surgeon should be done8 | |
| How many patients required ICU/setup, Is their any score to predict it preoperatively. | Spine surgery and high risk surgery will need shifting to ICU and extubation may be done in isolation ward or ICU for such cases.Local scores/guidelines be developed.6,8 | |
| What was the Cause of postoperative fever/aggravation- is it iatrogenic/nosocomial/asymptomatic flare up or patient was in incubation period | Patients (asymptomatic also) should be watched in ward for worsening or development of new symptoms4,15 | |
| Did fracture increase mortality in COVID patient, What fracture did to COVID, Was there any deterioration postop kidney function, DVT, embolism etc. asymptomatic patients became symptomatic? | Fracture with COVID carry increase mortality so be vigilant and have HDU as prophylactic post op wards and high risk patients intubated as in aforesaid till patient stabilizes. Asymptomatic may become symptomatic/develop pneumonia.11,13 | |
| What was the Rate of nosocomial infection | Nosocomial infection does occur, Doctors, nurses, patients, and families should be wearing protective devices such as an N95 respirator and goggles to decrease this complication.4 |
|
| What were the Rehab protocol/practices? Was post op weight bearing delayed or same | Rehabilitation should started as early as possible to avoid hypostatic pneumonia and respiratory rehabilitation is required to increase the capacity of lungs. Give handouts for physiotherapy and counseling for telehealth services.5,9,12,18 |
|
| What was discharge time, mean hospital stay | Variable depends upon patient stability. However as early as possible particularly in non COVID patients6,8 | |
| What were the postop medical prescription -antibiotic used, antiviral, HCQS, anticoagulant prophylaxis | Yes antivirals (Oseltamivir, lopinavir, ritonavir), Azithromycin and HCQS were used by several authors in various combinations and regimens, as per institution, as mentioned in results. These are evolving and authors suggest readers to consult recent literature updates.12,13 | |
| Are there any risk factors or preop screening tools to suggest increased mortality/morbidity risk-fracture type, polytrauma? Is smoking,diabetes, immunosuppressive disorder or drug-a factor? | Spine surgery, elderly comorbid hip fracture surgery, patient with COVID pneumonia, polytrauma all carried increased risk. Preoperativiely pO2 <90 and temperature > po2 deg.C, SHIFT tool>13, ASA grade >4, smokinig etc increased risk.6,11,12,19 | |
| What is the mortality rate of COVID with fracture/spine/hip | In our review of 44 cases of COVID with fracture, there were total 16 deaths; mostly due to respiratory failure (one case had hematuria also). Pneumonia and respiratory failure, kidney dysfunction were common cause of death.1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 | |
We have noticed a massive breakdown in trauma orthopedic fracture surgeries in the world during the COVID-19 pandemic. The main approach of most orthopedic surgeons was to save the hospital resources, to decrease the risks of a nosocomial infection like COVID-19 and to protect their staff and colleagues.
Due to imposed quarantines, travel bans and lockdown, forcing the people to stay at home, there is a substantial decrease in MVA which has caused a reduction in visits to the emergency trauma service. The mean age of the patients with a fracture, in this series, was found to be around 67 years. It is intuitive that younger age groups did not suffer fractures, perhaps due to restrictions on travel on the road, sporting activities, industrial activities etc., and the majority of these patients had a low velocity or a fragility fracture in an older person with osteoporosis. The male to female ratio was 24/20, which is not significant. Recent articles demonstrated that despite the decreased frequency of accidental trauma over the course of the COVID-19 the outbreak, the number of osteoporotic hip fractures remained stable.8,16,17 Zhu et al.16 reported hip fracture and low-energy injury (fall from standing height and fall from a low height) as most the prevalent injury mechanism, and the home being the place where these injuries commonly occurred. These findings highlighted the importance of primary prevention (home prevention) measures, and could be used for references for individuals, health care providers, or health administrators.16
Hip fractures in the elderly are overwhelming injuries that frequently result in long-term disability and can lead to death. Recent studies have shown that elderly patients with fractures associated with medical comorbidities such as diabetes, hypertension, COPD, and obesity are more badly affected by COVID-19 infections, due to their reduced functional reserves and weakened immune systems.4,12 These patients should be operated as soon as they are medically optimized, as any operative delays beyond 48 h after admission may increase the odds of 30-day all-cause mortality.17,25 This dictum is also applicable to the patients with COVID-19 infection, despite their higher mortality rate, as they might benefit from early surgery.11 In elderly patients with COVID-19 and proximal femoral fractures, surgery may contribute to the overall stability, early mobilization, improvement in respiratory physiology, and overall patient comfort. However, cases with severe dyspnea (pO2 <90%), hyperpyrexia (>38C), and signs of pneumonia or systemic organ dysfunction, are considered serious, and if present these patients should not be considered for orthopedic surgery (Fig. 7).12

Flow diagram for management of hip fractures during COVID-19 pandemic.(CCCAATTT is an acronym for Containment zone, Contact with COVID positive patient, Cough, Aarogya Setu app indication of himself and patients’, Travel, health Trouble and Temperature).
An accelerated care pathway should be adopted for a shorter length of hospital stay and subsequently early discharge of patients from the hospital. We suggest that in countries and healthcare facilities where the resources for orthopedic surgery and critical care are not very well developed, the conservative management still has a role to play, in the present pandemic situation.26 Several non-obligatory fractures can very well be managed conservatively. Rabie et al. have recommended non-operative treatments as preferred methods of treatment for most orthopedic problems, specifically the fractures.26 Flexibility and dynamicity in planning and treatment selection are important. General condition and severity of coronavirus infection in a patient, risk of surgery for both the patient and staff in positive cases and risk of in-hospital transmission to other patients should all be considered while deciding surgery.13 Shariyate et al.15 opined that old hip fracture patients, if having other underlying medical conditions that may lead to a lengthy hospital stay, may increase the chances of transmitting the infection to the health care workers and other patients. Also, a higher death rate is seen in these elderly people, possibly due to a weaker immune system, which also permits faster progression of viral infection. Finally, the stress associated with the fracture and the surgery might itself trigger a series of oxidative stress responses and excessive inflammation leading to a more severe course of infection. Hence, it is advisable to carefully evaluate these elderly patients (with fragility fractures) for surgery, during an outbreak of COVID-19 in order to protect themselves and the health care workers attending to them.15
The recent COVID Surg multicenter collaborative study included all patients undergoing surgery and having SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery at 235 hospitals in 24 countries and assessed 30-day postoperative mortality,7-day mortality and pulmonary complications. Out of 1128 patients 835 had emergency surgery and 280 had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 patients. 30-day mortality was 23·8% and 7-day mortality was 5·2% (higher risk for ASA grades 3–5 and lower risk for postoperative diagnosis). Pulmonary complications happened in 51·2% cases; and 30-day mortality among these cases was 38·0%, accounting for 81·7% of all deaths. In adjusted analyses, 30-day mortality was associated with male sex, age 70 years or older, major surgery, emergency surgery, malignant versus benign or obstetric diagnosis, and higher ASA grades. Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality.27
There were 299 orthopedic cases, out of which 131 (44.3%) had pulmonary complications and 86 (28.8%) had expired. There were 224 trauma cases, out of which 110 (49·6%) had pulmonary complications and 67 (29·9%) had expired. In the accompanying appendix, authors report that there were 66 cases of hemiarthroplasty (1 elective), 49 cases of dynamic hip screw (1 elective), 37 cases of intramedullary nailing (1 elective), 15 cases of closed reduction and internal fixation of fracture, 12 cases of open reduction and extra medullary fracture fixation, 15 cases of closed reduction and internal fixation of fracture, 2 cases of closed reduction and external fixation of fracture, and minor procedures included 1 closed reduction of joint and 2 open reductions without fixation. Separate prognostic details on fracture cases was, however, not mentioned except for emergency or elective surgery and major or minor status. Authors suggest that thresholds for surgery during the COVID-19 pandemic should be elevated, particularly in men aged 70 years or more. Non-urgent procedures may be postponed and non-operative treatment should be promoted to delay or avoid the need for surgery. Strategies to reduce in-hospital SARS-CoV-2 transmission and the risk of postoperative complications should be planned.27
American Society of Anesthesiologists (ASA) classification is certainly a useful tool for foreseeing the patients’ outcome significant trend an increase in the ASA physical status is associated with higher perioperative mortality in ICU.28 The only independent predictor for 30-day pulmonary complications in COVIDSurg Collaborative study was ASA grades 3–5. Also, ASA grades 3–5 versus grades 1–2 was associated with increased odds of 7-day mortality.27
Nunez et al.17 have also warned that contingency plans should not automatically assume that all the trauma cases will decrease during a pandemic. Osteoporotic hip fractures remain stable. Given that osteoporotic hip fractures are in geriatric population with multiple comorbidities, operative delays may increase the risk of mortality as well as of nosocomial infection, and if possible, one should be prepared for the surgical care of these fractures, even in pandemic situations.17 Mi et al.4 from their experience of 10 fracture cases with COVID-19 pneumonia, has recommended four main strategies; i) non-operative treatment should be preferred for elderly cases with minor fractures, like distal radial fractures, in endemic areas, ii) infection-control measures should be implemented strictly for cases with fractures, particularly those for surgical treatment, iii) COVID-19 pneumonia cases with a fracture should be given intensive surveillance and treatment, and iv) surgery for cases with a fracture and COVID-19 pneumonia should be done in a negative-pressure operating room.
Post-operative patients are a vulnerable group at risk of nosocomial SARS-CoV-2 infection and might be particularly susceptible to subsequent pulmonary complications like pneumonia, acute respiratory distress syndrome (ARDS), respiratory failure or unexpected postoperative ventilation which can be invasive or noninvasive. These complications are due to pro-inflammatory cytokine and immunosuppressive responses to surgery and mechanical ventilation.27 Patients with COVID-19 infection are at high risk of developing thromboembolic complications. It is advisable to use at least standard doses of low-molecular-weight heparin, unfractionated heparin or fondaparinux in all post-operative patients unless contraindicated. If pharmacological prophylaxis is contraindicated, a mechanical thromboprophylaxis with the use of elastic socks and intermittent pneumatic compression can be used in patients at highest risk.29, 30, 31 An extension of thromboprophylaxis at hospital discharge should be advised, according to the individual risk, including active mobilization.
The resumption of elective orthopedic surgery should be withheld for the time being and only emergency and semi-urgent cases should be operated, as of now.32,33 The orthopedic and trauma surgery which is likely to produce more aerosol, more invasion, requiring general anesthesia and prolonged-time must be avoided.26
4.1. Strength and limitations of the study
The strength of this study lies in being able to find 20 relevant studies for analysis, related to fracture management amidst COVID 19 Pandemic. Furthermore, we could analyze 112 COVID positive cases, associated with the fractures. We could not find any published data on such a large number of cases, for this subset of patients.
The current study also has some limitations. Firstly, the studies were heterogeneous in nature, from different geographical populations. Secondly, some studies were focused on proximal femoral fractures, some on spinal injuries, and others on all types of fractures. Therefore there is a lack of uniformity in the patient populations, which may be related to the risk of mortality and morbidity. Thirdly, the follow up period of the published studies was quite short and final outcomes of fracture treatments and union rates have not been reported so far.
5. Conclusion
COVID-19 has led to a significant reduction in a load of fracture patients globally, though the incidence of fragility fractures continues to be unaffected. Conservative treatment should be adopted as far as possible in non-obligatory fractures and in lesser equipped centers. Surgery in patients with obligatory fractures like proximal femur fragility fractures, compound fractures/dislocations and severe limb injuries require surgical intervention, under due care. The mortality rates are higher in elderly, patients with medical comorbidities and COVID positive patients, with fractures and these constitute a high-risk group. The resumption of routine trauma and elective orthopedic surgery should only be done in a gradual manner, and after taking due precautions.
