The use of interfragmentary positional screw in minimally invasive plate osteosynthesis for simple distal femur fractures in elderly patients: A retrospective, single-centre pilot study

摘要

Introduction: Minimally invasive plate osteosynthesis (MIPO) using locking plates has been used in distal femur fractures, but various problems, such as nonunion, malalignment, and implant failure, have been reported. Simple fractures sometimes have poorer outcomes than complex fractures. We studied elderly patients with simple fracture patterns who underwent open reduction followed by placement of a single positional screw to hold the reduced interfragmentary gap, and compared these cases with patients who underwent surgery using conventional MIPO techniques.
