Comparative Analysis of Infrapatellar and Suprapatellar Nailing Techniques for Tibial Shaft Fractures

Abstract

Introduction: Tibial shaft fractures pose a significant challenge in orthopaedic practice, often necessitating surgical intervention for optimal recovery. The selection of the entry point for intramedullary nailing, particularly between the suprapatellar and infrapatellar approaches, remains a debated aspect in fracture management. While both approaches aim to restore stability and function, their nuances influence outcomes and patient experiences. This study aims to comprehensively compare the suprapatellar and infrapatellar approaches, analyzing surgical techniques, complications, and functional outcomes to inform clinical decision-making. Methodology: A retrospective comparative analysis was conducted on patients undergoing intramedullary nailing for tibial shaft fractures, comparing outcomes between the suprapatellar and infrapatellar approaches. Data collection included patient demographics, fracture characteristics, intraoperative details, and postoperative outcomes. Statistical analysis was performed using appropriate tests, with a significance level set at p < 0.05. Result: Operative time was longer in the infrapatellar group (137.8 minutes) compared to the suprapatellar group (114.4 minutes). The mean radiation dose was higher in the infrapatellar group (74.3 cGY/cm2) and lower in the suprapatellar group (48.5 cGY/cm2). Postoperative outcomes showed a mean Lysholm score of 74 in the infrapatellar group and 90 in the suprapatellar group. one case of infection and one case of malunion were reported in the infrapatellar group, while the suprapatellar group had one infection case but no instances of non-union or malunion. Conclusion: This study provides valuable insights into the surgical and clinical outcomes of the suprapatellar and infrapatellar approaches for tibial shaft fractures. While both techniques offer viable options, the suprapatellar approach may offer advantages in terms of operative efficiency and functional recovery.
