Distal Femoral Non-union: Moving Forward with a Systematic Approach

This systematic review sheds fresh light on the challenging realm of distal femoral non-union management. Distal femur fractures are common, and non-union presents a significant hurdle for patients and surgeons alike. https://link.springer.com/article/10.1007/s43465-024-01205-4

Management of Distal Femoral Non-union: A Systematic Review - Indian Journal of Orthopaedics

Introduction Managing distal femur fracture nonunion is complex, with unpredictable results. The present investigation systematically updates current evidence, reviews existing modalities, innovations and related outcomes, and discusses future perspectives on the management of nonunion of the distal femur. Methods This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: the 2020 PRISMA statement. In April 2024, PubMed, Web of Science, Google Scholar, and Embase were accessed without time constraints. No additional filters were used in the database search. All the clinical studies investigating treatment options for nonunion of distal femur fractures were accessed. Results 35 clinical studies (832 patients) were included. Of them, 34.2% (239 of 698 patients) reported an open fracture, and 24.5% (78 of 319 patients) reported infection at the fracture site. The mean length of the follow-up was 28.9 ± 13.2 months. The mean age of the patients was 53.8 ± 14.7 years. Conclusion 84.5% (703 of 832) of patients reached complete union without major complications, and 3.8% (32 of 832) reached complete union with major complications at a mean of 21.7 ± 20.9 months. 8.7% (72 of 832) patients showed signs of persistent non-union. Level of evidence Level III, systematic review.

This study offers valuable insights. The authors meticulously combed through major databases, amassing data on over 800 patients. The findings paint a detailed picture: a substantial portion (nearly 35%) had open fractures, and concerningly, a quarter harbored infection at the fracture site. These factors undoubtedly complicate the healing process.

The good news is that over 84% of patients achieved complete union, highlighting the effectiveness of current treatment strategies. However, the lingering non-union rate of nearly 9% underscores the need for continued exploration and refinement of techniques.

The review delves into various treatment modalities, though specific details are absent from this abstract. Future directions hinted at by the authors are intriguing. Can innovative technologies offer a path towards improved outcomes?

This systematic review provides a valuable springboard for further investigation. By building on this comprehensive data set and delving deeper into treatment methods and patient characteristics, researchers can refine our understanding of this complex problem. Ultimately, the goal is to ensure consistent and optimal outcomes for all patients facing the challenge of distal femoral non-union.
