Functional outcomes of DCS (dynamic condylar screw) plate for management of distal femur fractures

Abstract

Introduction: the dynamic condylar screw (DCS) plate is an angular stable fixation (95°) system for distal femur fractures that allows for the ability to apply compression across the femoral condyles. The aim of this study was to evaluate our experience treating distal femur fractures with this device and give the long-term outcome. Methods: A retrospective study was undertaken in our institution during the period from August 2020 to September 2021. A total number of 40 patients with distal femur fractures were managed using DCS plate system and included in the study. The mean follow-up period was 12 months (6 to 18 months). Clinico-radiological progression of fracture union as well as the functional outcome was studied. Results: most of the fractures were closed injuries in young male patients resulting from traffic accidents. The average time to union was 12.6 weeks (range 11 - 23). Two patients (5%) suffered superficial infection. Non-union in one cases (2.5%). Implant loosening seen in one (2.5%) and knee joint stiffness seen in one patient. At final follow-up, the mean range of motion (ROM) of knee was 115.7° (100°-148°). The mean NEER’s Knee Score was 84.5 (59 - 94) translating to good clinical results.Conclusion: our study conclusively establishes that excellent functional outcome can be achieved with DCS plate inserted with skilled surgical technique in distal femur fractures including the ones that are communited or occurring in osteoporotic bone with a negligible complication rates.
