Antegrade vs Retrograde Intra-Medullary Nailing in Femoral Shaft Fractures: A Systematic Review and Meta-Analysis.

OBJECTIVES

Femoral shaft fractures are one of the most prevalent fractures found in clinical practice. Numerous operative and non-operative options are readily available for the treatment of such fractures with intra-medullary nailing being the gold standard. To date, no consensus has been reached favoring one approach over the other. Thus, this meta-analysis aims to compare the outcomes between an antegrade and retrograde intra-medullary nailing for the treatment of femoral shaft fractures.

METHODS

PubMed, Cochrane, Google Scholar (page 1-20), and Embase were searched till January 2024. The clinical outcomes evaluated were the incidence of adverse events, reoperations, hip and knee pain, and surgery-related parameters.

RESULTS

Higher rates of hip pain, and heterotopic ossification (p=0.0003, and p=0.0002 respectively) was observed with antegrade nailing. However, a higher rate of knee pain (p=0.02) was appreciated in retrograde nailing. There was no statistically significant difference in the remaining analyzed outcomes such as operative time, reoperation rate or other complications.

CONCLUSION

Despite a higher rate of heterotopic ossification using the antegrade nailing technique, both the antegrade and retrograde nailing techniques yield overall similar outcomes. Therefore, the decision to choose one or the other should be based on patient-related factors, and the surgeon's experience and preference.
