Mouzopoulos 2008.
| Methods | Method of randomisation: alternation | |
| Participants | Orthopaedic unit in Athens, Greece From April 1999 to April 2002 129 patients with a displaced intracapsular fracture. Mean age: 74 years (range not stated) Percentage male: 31 (28% of 109) Follow‐up: mean 48 months Loss to follow‐up: 2 (4%) lost but in addition, 8 excluded because of previous hip fracture and 18 patients who had revision surgery were not followed‐up for the functional assessments. Inclusions: age over 70 years, good cognitive function, moderately dependent, displaced intracapsular fracture Exclusions: Pagets disease, history of cancer, rheumatoid arthritis |
|
| Interventions | 1. Internal fixation with a Sliding Hip Screw
versus: 2. Merte hemiarthroplasty versus 3. De Puy total hip replacement. It was not stated if the prostheses were cemented in place |
|
| Outcomes | Follow‐up for 48 months OUTCOMES COLLECTED BY TRIAL (a) Operative details: none (b) Complications related to type of operation Re‐operations (1 and 4 years) (c) Postoperative complications: none (d) Postoperative care outcomes: Length of hospital stay (e) Anatomical restoration: none (f) Final outcome measures: Mortality (1 and 4 years) Barthel score (1 and 4 years) Harris hip score (1 and 4 years) Range of movement Walking speed (g) Economic cost: none | |
| Notes | Eight patients who had had a previous hip fracture and 18 patients who had a revision operation were excluded from the follow‐up assessments. | |
| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | High risk | 'these 129 participants were randomly divided, by two orthopaedic surgeons, into three groups according to the type of surgical operation there were to undergo, following this order: hemi‐arthroplasty, total arthroplasty, internal fixation, etc" |
| Allocation concealment (selection bias) | High risk | alternation: as above |
| Blinding (performance bias and detection bias) Were the assessors of pain and function at follow‐up blinded to the treatment allocation | Low risk | Assessors of function were blinded to the type of surgery |
