Comparison of clinical and radiological outcomes in intertrochanteric fractures treated with InterTAN nail against conventional cephalomedullary nails: a systematic review

Intertrochanteric fractures, accountable for 50% of hip can be fixed with cephalomedullary devices such as Proximal Femoral Nail Antirotation (PFNA™), Gamma3 nailing system and TRIGEN™ InterTAN™ nail (IT). IT uniquely uses two cephalocervical screws that allow linear compression provide additional resistance to femoral head rotation. A literature review assessing clinical outcomes these was conducted, 14 studies enrolling 3104 patients meeting the inclusion criteria. PFNA had better intraoperative compared IT; however, superior implant-related cut-out screw migration. No difference found between or in Harris Hip Scores, time union, malunion nonunion. Further long-term are needed evaluate cost–effectiveness devices.
