It allows early rehabilitation and functional recovery and reduces the risk of postoperative complications 7. Surgical treatment represents the optimal strategy for managing intertrochanteric fractures. Hip fractures include femoral neck and intertrochanteric factures 4 20 to 30 percent of patients died in the first 12 months after an intertrochanteric fracture, especially those elderly with limited activity 5, 6. The 1-year mortality for hip fractures range from 14% to 36% 3. By 2050, the number of hip fractures is estimated to surpass 6.3 million 2. Hip fractures represent a common type of injuries its number increases rapidly 1. Future randomized trials or observational studies that are carefully designed and conducted are warranted to establish the effects of alternative internal fixation strategies for intertrochanteric fracture. However, a number of trials compared two commonly used internal fixation strategies, gamma nail (GN) and sliding hip screw (SHS). Because of these, no statistically significant differences were present from most of the comparisons across all the outcomes and no definitive conclusions can be made. Their risk of bias was generally unclear due to insufficient reporting. We ultimately included 43 trials enrolling 6911 patients most trials were small in sample sizes and events. We searched PubMed, EMBASE and CENTRAL for RCTs that compared different internal fixation implants in patients with intertrochanteric fracture at 6-month follow-up or longer. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to address this important issue. The relative effects of internal fixation strategies for intertrochanteric fracture after operation remain uncertain.
