BACKGROUND: Internal fixation, commonly used for extracapsular hip fractures, may fail particularly in unstable fractures. Replacement of the hip using arthroplasty, often used for intracapsular fractures, has been used as an alternative. OBJECTIVES: To compare replacement arthroplasty with internal fixation for the treatment of extracapsular hip fractures in adults. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group's trials register and bibliographies of published papers, and contacted colleagues. Date of the most recent search: August 1999. SELECTION CRITERIA: Randomised and quasi-randomised trials comparing replacement arthroplasty with an internal fixation implant for skeletally mature patients with an extracapsular hip fracture. DATA COLLECTION AND ANALYSIS: Both reviewers independently assessed trial quality, using a ten item scale, and extracted data. Additional information was sought from trialists. Odds ratios and 99% confidence intervals were calculated for relevant dichotomous outcomes and presented graphically. MAIN RESULTS: Only one randomised trial of 90 patients with unstable extracapsular hip femoral fractures in the trochanteric region was identified and included in this review. This compared arthroplasty with a sliding hip screw and was of poor methodological quality. From the limited data available for this trial, there were no significant differences between the two methods of treatment for operating time, local wound complications, mortality rate or mobility of previously independent patients. There was however a reportedly higher blood transfusion need in the arthroplasty group. REVIEWER'S CONCLUSIONS: There is insufficient evidence from randomised trials to determine whether replacement arthroplasty has any advantage over the sliding hip screw for extracapsular hip fractures. Further well designed randomised trials for the treatment of these fractures for this comparison are required.
BACKGROUND: Many different surgical techniques, such as osteotomy, have been used in internal fixation of extracapsular hip fractures. OBJECTIVES: To compare different aspects of surgical technique in internal fixation of extracapsular hip fractures that have been subjected to randomised trials in adults. SEARCH STRATEGY: The Cochrane Musculoskeletal Injuries Group trials register, Medline, CENTRAL and reference lists of relevant articles were searched. Date of the most recent search: March 1999. SELECTION CRITERIA: All randomised and quasi-randomised trials investigating operative technique for the treatment of extracapsular hip fractures. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trial quality, by use of an eleven item check list, and extracted data. Wherever possible and appropriate, results of outcome measures were pooled. MAIN RESULTS: All eight included trials were of only modest methodological quality. One trial of 65 patients undergoing fixation with a fixed nail-plate compared osteotomy versus anatomical reduction. There was a tendency to a reduced fixation failure rate after osteotomy. Four trials involving 465 patients undergoing fixation with a sliding hip screw (SHS) compared osteotomy versus anatomical reduction. Osteotomy was associated with an increased operative blood loss and length of surgery. There was also a tendency to an increased length of hospital stay and limb shortening for osteotomy. One trial of 200 patients undergoing fixation with a SHS compared results with or without compression across the fracture site. The only significant difference in outcomes was increased varus deformity in those fractures treated with compression. One trial of 19 patients reported reduced temperatures generated by a modified method of reaming the femoral head. Another study used oesophageal ultrasound to demonstrate reduced bone marrow intravascular embolism when a Gamma nail was inserted in 50 patients with, rather than without, a distal pressure venting hole in the femur. REVIEWER'S CONCLUSIONS: There is inadequate evidence to determine if any benefits exist for the routine use of osteotomy in conjunction with a SHS for the internal fixation of an unstable trochanteric femoral fracture. Osteotomy may be relevant if used in conjunction with a fixed nail plate. Based on the evidence of one trial only, there is inadequate evidence to support the application of compression across the fracture site of a trochanteric fracture during SHS fixation. Inadequate information exists for different reaming techniques during SHS or Gamma nail fixation to make definite conclusions.
