Evaluation of functional outcome of double locking plates for the treatment of Intraarticular distal femur fractures.

Abstract

Introduction:Fractures of the distal femur are difficult orthopaedic injuries, frequently the consequence of high-velocity trauma and carrying a high morbidity rate.Traditional management approaches have evolved towards surgical intervention, specifically ORIF (open reduction and internal fixation), to address the complex nature of these fractures. While condylar buttress plates were once commonly utilized, modern fixed-angle implants, such as lateral locking plates, have demonstrated superior biomechanical properties. However, concerns persist regarding varus collapse and instability, particularly in cases with significant comminution.

Methods and materials: In this prospective study conducted between January 2021 and January 2022, we evaluated the efficacy of a novel double-plating technique in distal femur fracture management. Twenty-two patients meeting specific inclusion criteria underwent surgical treatment utilizing both lateral and medial fixation. Pre-operative evaluation, operative techniques, and post-operative management were standardized across all cases with a follow-up period of 1 year.

Results: Our results demonstrate promising outcomes with a 100% union rate and a mean healing time of 16-24 weeks. Functional findingshave been predominantly good to excellent, with a significant proportion of patients achieving a range of motion exceeding 90°. Notably, no varus deformities were observed postoperatively, highlighting the efficacy of the dual-plating technique in maintaining anatomical alignment and preventing complications.

Conclusion: Our research underscores the importance of individualized treatment strategies in the distal femur fractures management, with a focus on achieving anatomical reduction, stable fixation, and early mobilization. Further research with the larger cohorts as well as long-term follow-up is warranted to validate the efficacy and durability of the double-plating technique in optimizing patient outcomes and enhancing the quality of care for individuals with distal femur fractures.
