Comparison of Patient Reported Outcomes Following Suprapatellar Versus Infrapatellar Nailing Techniques for Tibial Shaft Fractures: A Systematic Review and Meta-analysis.
2021
OBJECTIVES To compare patient reported outcome measures (PROMs) between patients who underwent IMN fixation for tibial shaft fractures using an IP or the newer SP approach. Secondary outcomes included fluoroscopic radiation exposure, operative time, and radiographic outcomes. DATA SOURCES A systematic literature search of the databases Ovid MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials Study Selection. STUDY SELECTION Level I to III studies in which patients over the age of 18 with acute tibial shaft fractures who underwent tibial IMN fixation using an IP or SP approach for fracture fixation were assessed for inclusion. Studies with a minimum of 10 patients in each cohort that reported on post-operative patient-reported outcomes with at least six months follow up were included for analysis.Data Extraction and Synthesis: Twelve studies which reported PROMs and compared IP and SP intramedullary nailing of tibial shaft fractures were analyzed. This included 654 patients who underwent IP IMN fixation and 542 patients who underwent SP IMN fixation. A random-effects model for unadjusted/crude study estimates were pooled using inverse variance (IV) weighting for continuous variable analysis. CONCLUSIONS This review found a significant improvement in PROM for patients with tibial shaft fractures when the SP IMN technique was utilized. In addition, there was a significant decrease in intraoperative fluoroscopy time consistent with other radiographic findings demonstrating improved start point accuracy and reduction with SP IMN fixation of tibial shaft fractures. LEVEL OF EVIDENCE Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
