May minimally invasive plate osteosynthesis be an alternative to intramedullary nailing in selected spiral oblique and spiral wedge tibial shaft fractures?

Abstract

Objectives: This study aims to compare intramedullary nailing (IMN) and minimally invasive plate osteosynthesis (MIPO) treatment methods in Arbeitsgemeinschaft für Osteosynthesefragen (AO) 42A1 & 42B1 selected tibial shaft fractures.

Patients and methods: Fifty-one patients (31 males, 20 females; mean age 43.5±14.2 years; range, 18 to 81 years) operated for AO 42A1 or AO 42B1 tibial shaft fractures between January 2006 and January 2012 were retrospectively evaluated. Twenty-three of these patients were treated with MIPO and 28 with IMN. Patients were compared in terms of union time, return to work, infection, malunion, hospital stay, and sixth month and two-year Lower Extremity Functional Scale (LEFS) values.

Results: There was no difference between the MIPO and IMN groups in terms of demographic data, etiology, and fracture patterns. The mean follow-up time was 37.8±8.8 months in MIPO group and 35.9±8.7 months in IMN group. Union time (p=0.575), return to work (p=0.155), infection (p=0.643), malunion (p=0.471), and hospital stay (p=0.538) were all similar between groups. Although the LEFS value was higher in IMN group in sixth month (p=0.026), the two-year LEFS value was similar between groups (p=0.085).

Conclusion: Results of the study showed that both treatment methods are similar regarding clinical and functional outcomes. According to these results, MIPO can be recommended as an alternative to IMN in tibial shaft fractures formed as spiral oblique and spiral wedge.
