BACKGROUND: Intertrochanteric hip fractures are associated with high morbidity and mortality rates. Percutaneous compression plating (PCCP) is a minimally invasive technique for fracture fixation that has been advocated to reduce blood loss, relieve pain, and lead to faster rehabilitation. The present systematic review and meta-analysis was performed to evaluate PCCP in patients with intertrochanteric hip fractures compared with patients with sliding hip screw (SHS).
METHODS: A comprehensive review of related literature was conducted to identify all articles in PubMed, EMBASE, Springer, Ovid, China National Knowledge Infrastructure (CNKI), and the Cochrane Central Register of Controlled Trials published on or before July 26th, 2011. Only prospective or retrospective comparative studies reporting clinical and radiographic outcomes of PCCP for intertrochanteric hip fractures were included. The methodological qualities of the included studies were assessed using the Coleman methodology score, and the reported data of individual studies were extracted. Meta-analytic pooling of group outcomes across studies was performed for both the PCCP and SHS techniques.
RESULTS: Fourteen studies met the inclusion criteria. Minimally invasive PCCP was associated with a decrease in surgical time, blood loss, transfusion rate, and systematic complications. No significant differences between PCCP and SHS were observed in other parameters, including hospital stay, mortality, reoperation, implant-related complications.
CONCLUSIONS: Based on these finding, PCCP appeared similar to SHS in terms of mechanical stability in the clinical setting, but had obvious advantages in terms of blood loss, transfusion need, and systematic complications, which may be attributed to reduced soft tissue and bone damage. Although orthopedic surgeons are advised to consider PCCP fixation as an additional alternative treatment for intertrochanteric fractures, high-quality randomized trials are still needed to assess the benefits of this minimally invasive technique.
