Abstract
OBJECTIVES: Intertrochanteric hip fractures are a common orthopaedic injury in the United States. Complications of surgical treatment include nonunion, lag screw cutout, implant failure, post-operative pain, risk of refracture or reoperation, and infection. The purpose of this study was to compare the rate of complications of sliding hip screw fixation (SHS) compared to cephalomedullary nailing (CMN) for the treatment of closed intertrochanteric femur fractures in adult patients. METHODS: PubMed, CINAHL, and Cochrane Library databases were searched for studies comparing SHS to CMN in the treatment of closed intertrochanteric femur fractures in adults. Data were compiled to observe the rate of nonunion, cutout failure, infection, refracture, perioperative blood loss, reoperation, postoperative pain, pulmonary embolism/deep venous thrombosis (DVT), length of hospital stay, and mortality. RESULTS: Seventeen studies were included comprising 1,500 patients treated with SHS and 1,890 patients treated with CMN. Treatment of intertrochanteric femur fractures with SHS demonstrated significantly fewer refractures and reoperations. There was no significant difference in other variables between SHS and CMN treated groups. CONCLUSION: This meta-analysis shows that the only notable difference in outcomes is patients treated with CMN have a higher rate of refracture and reoperation. With new advances in the development of both CMNs and SHS, further studies will be required to see if these differences persist in the coming years.
