摘要：Intertrochanteric fractures are common injuries in the elderly. Conventional intramedullary nails including Gamma 3 locking nail and proximal femoral nail antirotation (PFNA) were designed for unstable intertrochanteric fractures. The InterTan (IT) nail system, introduced in 2005, has been reported superior biomechanical and clinical outcomes compared with 1-screw nailing system. However, some recent studies have reported that IT did not improve functional recovery in patients with intertrochanteric fractures. Randomized controlled trials (RCTs) or prospective cohort studies were included in our meta-analysis. We used the PRISMA guidelines and Cochrane Handbook to evaluate the quality of included studies to ensure that the pooled data of our meta-analysis were reliable and veritable. Our pooled data analysis demonstrated that IT was as effective as the control group in terms of Harris Hip Score (HHS), blood loss, total complications, union time, length of hospital stay, revision rate, and fluoroscopy time. IT shows less implant cut-out rate and femoral fractures when compared with control groups.
