Abstract

Introduction

Proximal physeal fracture of the medial clavicular physis is a rare specific injury occurring in the immature skeletal. Several studies describe unilateral cases with posterior or anterior displacement and the following complications (vascular and mediastinal compression). An immediate diagnosis and management are necessary to avoid complications. The clinical diagnostic might be obvious or difficult, pain and swelling in the sternoclavicular joint area, sometimes a deformity and focal tenderness. A chest X-Ray may help and a three-dimensional reconstructed computed tomography scan has to be done to evaluate the lesions before surgery. The imaging is useful to confirm and specify the diagnostic and the displacement.

Presentation of case

This case report presents 4 cases of proximal physeal fracture of the medial clavicular physis in 2 male-teenagers with bilateral displacement, one posterior and the other asymmetric.

Discussion

After reviewing the literature of the unilateral clavicular physeal fracture, we can conclude that the ideal management of these injuries has not been well described. An open reduction associated an osteosuture with non-resorbable suture was performed. One-year follow-up, both of them had full recovery without any functional impact or any complains. This management of the proximal physeal fracture of the medial clavicle on children shows an excellent result according our cases and the literature.

Conclusion

The purpose of this study is to evaluate the functional impact of osteosuture in medial bilateral clavicular physeal fracture in teenagers after 1-year follow-up.

1. Introduction

Clavicular physeal fracture is an uncommon pediatric fracture [[1], [2], [3], [4], [5], [6], [7], [8], [9]], especially bilateral. The lesion is not the same as in adults, who have a sternoclavicular disjunction. In children, it is a physeal fracture, included in Salter & Harris classification [5,7,10]. The diagnosis, management and treatment totally differ in adults. These injuries mostly occur during sport activities [8], with high energy trauma, due to a direct force applied to the medial clavicle or an indirect force on the shoulder [1,3,6,9]. The clinical diagnostic might be obvious or difficult [8,10], pain and swelling in the sternoclavicular joint area [1], sometimes a deformity, focal tenderness [2] and a clinical instability. Therefore X-Ray and CT scan must be done [1,[3], [4], [5], [6]] in order to confirm the diagnosis [10]. Three-dimensional reconstructed computed tomography scans may help [2,3] to evaluate the lesions before surgery. Several complications [8,10], such as tracheal or vascular compression [11,12], which are revealed by dyspnea, dysphagia [1,5] or odynophagia, can be noticed. Because of the risk of complications in retrosternal displacement [8,9] of the medial clavicular metaphysis, a surgical treatment has to be performed [4,5,10,13]. The purpose of this treatment is different than in adults, the primary instability caused by the fracture will be resolute with the osteosuture and the bone healing. In adults, an arthrodesis is necessary to access the definitive stability of the sterno-clavicular articulation. The aim of this report is to demonstrate the functional impact on the medial bilateral clavicular physeal fracture after 1-year follow-up. This report explains 4 cases of proximal physeal fracture of the medial clavicular physis in two teenage boys treated surgically, one of them suffered from a bilateral posterior displacement of clavicular physeal fracture, and the other one, an asymmetric displacement clavicular physeal fracture.

The work has been reported in line with the SCARE criteria [14].

2. Materials and methods

This study has been drafted in accordance with the principles of the Helsinki Declaration.

In our center, we received 4 cases of proximal physeal fracture of the medial clavicular physis in two teenage boys. One of them, a 13-year-old skier, presented a bilateral proximal physeal fracture of the medial clavicular physis with a posterior displacement. He complained about dysphonia, dysphagia and dizziness. Initial radiography of the right clavicle was suspicious. A CT scan was performed finding a left physeal fracture with posterior (Salter and Harris I) and a right physeal fracture with posterior displacement (Salter and Harris II) associated with a 4-cm hematoma.

The other one, a 15-year-old boy sustained a high-energy trauma, presented a bilateral proximal physeal fracture of the medial clavicular physis with an asymmetric displacement. A chest X-Ray was performed and wasn’t contributive. The CT-scan showed a left physeal fracture with posterior displacement (Salter and Harris I) and a right physeal fracture with anterior (Salter and Harris I) displacement. The diagnosis was uncertain about the right injury but confirmed intraoperatively because of the clinical instability.

Surgical Technique: Surgical treatment of these injuries was performed under general anesthesia after consent of the patients and their legal representatives by an orthopaedic paediatric surgeon. The patient was lying in the supine position, arms stretched along the body. After asepsis, a draping taking both clavicles was carried out (Fig. 1). An arcuate incision centered on the right sternoclavicular joint was performed in the first place. The incision was then continued over the defect to the physis and then to the articulation while the hemostasis was achieved. Once the lesions were exposed after dissection, right physeal fracture with posterior displacement was confirmed as seen in the tomography scan (Fig. 2, Fig. 3). The clavicle was reduced using a bone hook. Stability was then reassessed and the periosteal incision was closed with three non resorbable simple stitches with Mersuture® 1 to perform the osteosuture (ORIF: Open Reduction and Internal Fixation) (Fig. 4). A drain was necessary and the closing was achieved with 5-0 resorbable rapid sutures. The same procedure was carried out on the other side. Any vascular complication was notice during the intervention. After the surgery, the patient was kept in a shoulder immobilizer only for post-operative care in order to reduce the pain, during approximately 24 h.

The Disabilities of the Arm, Shoulder and Hand (DASH) Score (HAS) [16] can be used to appreciate the progress during the recovery.

To demonstrate the functional impact on the medial bilateral clavicular physeal fracture after 1-year follow-up, we used the DASH Score [16], the resumption of the sports activities and the cicatrization of the incisions.

3. Results

One-year follow-up, both of them had full recovery without any functional impact or any complains. The DASH Score (French National Authority for Health) [16] reached 100/100. The disability of practicing sports activities lasted 3 months at least. The scars on the clavicles were thin and didn’t occur any problem.

4. Discussion

The primary purpose of this study is to evaluate the functional prognostic of a displaced physeal clavicular fracture after a surgical treatment. The clavicular physeal fracture concern the pediatric population mostly the teenagers with an average of 13 year-old [0; 23] (Table 1). Usually it occurs during sports activities [2,3] after a direct fall on the shoulder [4,5]. In the first place, swelling and pain in the area of the sternoclavicular joint can be noticed with a limitation of the shoulder movements [6,7] and with the attitude of the upper limb’s traumatism.

According the literature, many patients presented immediate complications such as dysphagia [7,12], dyspnea [9,13] or vascular compression [13,15,16]. To avoid complications in the retrosternal structures by either the instable fragment or callus formation, an immediate surgical treatment has to be attempted [1,11]. In adults as in children, the risk of complications is the same due to the displacement and the compression.

Several authors [7,11,12] described, sometimes this kind of injuries can be missed in the first place. The recurrence of the pain with an initial clinical exam subtle and an inadequate imaging [12] can lead to a tardive diagnosis. A shortening of the acromio-clavicular distance may help to diagnose the fracture but can be less specific when the both clavicles are injured. The position of the clavicular epiphysis has to be found to specify the diagnosis. A clinical instability can reveal a reduced medial clavicular physeal fracture with a normal tomography scan. Despite the delayed diagnosis none of their patients present any functional complication [7,12]. Intraoperatively, the diagnosis can be more accurate [7] than the initial imaging could reveal. The difference between dislocation and physeal fracture can be determine intraoperatively [7]. The type of the fracture in the Salter & Harris classification [2,5,7] can be adjust during the surgery. Surgery is the only way to confirm the definitive diagnosis and allow the most appropriate treatment for the patient.

Many unilateral cases are described in the literature with diverse treatment : non operative [15], closed reduction [6,7,13] or ORIF with osteosuture [[2], [3], [4], [5],7]. Siebenmann [1] published a case series and review of the literature about the management of epiphysiolysis type Salter and Harris I of the medial clavicle with posterior displacement. He recommends an open reduction and fixation (ORIF) of the injury with posterior displacement. The term “epiphysiolysis” [1] is maladapted to characterize the lesion because there isn’t a lysis of the physis but a traumatism of the physis as describe by Salter and Harris. In our case, open reduction and osteosuture were performed bilaterally even if, in one of them, the displacement was anterior. This is an instable lesion so the orthopedic treatment is inadequate. This technique was used to avoid an asymmetric result and in order to have a good esthetic result. This treatment is easy to realize, affordable (surgical suture material mostly) and with excellent results.

It appears to be important to evaluate the functional prognostic of this injury in the follow-up [7,13]. Our patients reach a total of 100/100 after 1-year follow-up with the DASH Score [16]. Mostly return to sports activities between 3 months [4] and a 1 year of recovery [1,3] without any complication reported. Esthetic complications can be reported such as hypertrophic [7] or keloid scars [15] where a surgical revision can be useful. None of our patients complain of their scars.

5. Conclusion

This study and literature review demonstrate that a quick surgical treatment of the bilateral clavicular physeal fracture with anterior or posterior displacement has to be done. We highly recommend an ORIF with osteosuture using non resorbable sutures to avoid sequels and hoping a full recovery with a resumption of the sports activities. A thoracic three-dimensional reconstructed computed tomography scan has to be realize to define the lesion. This diagnosis is underreported because this fracture can be occult on imaging. Therefore, all skeletally immature patients with suspected sternoclavicular joint injury have to be carefully examined and especially the signs of complications such as vascular or mediastinal compression. The management of the physis fracture of the medial clavicle totally differ from the management of the sternoclavicular disjunction on the adult population, this is a specific diagnosis, treatment and recovery. The primary instability caused by the fracture will be resolute with the osteosuture and the bone healing.
