Distal femoral locked plate versus retrograde nail for extra articular distal femur fractures: A randomized comparative study

Background Distal femur fractures, particularly extra-articular types, pose significant challenges in orthopedic trauma. Objective To evaluate and compare the outcomes of LP and RN in treating extra-articular distal femur fractures, focusing on operative time, blood loss, functional recovery, union time, and complications. Patients and methods This prospective randomized clinical trial has been performed on 30 cases with extra-articular distal femur fractures. Patients were divided into two groups: Group A (n=15) treated with RN and Group B (n=15) treated with LP. Results Both groups showed similar demographic characteristics, with no significant differences in age or sex distribution. The mean time to union was 12.93 weeks for RN and 14.87 weeks for LP (p=0.342). Functional outcomes, measured by LEFS, were comparable between groups, with insignificant variances in knee range of motion or complication rates (infection, stiffness, delayed union, nonunion, and knee pain). Conclusion Both RN and LP are effective for managing extra-articular distal femur fractures, with similar operative and postoperative outcomes. The choice of techniques must be individualized depending on fracture pattern, soft tissue condition, and surgeon expertise.
