The level of fibula osteotomy and incidence of peroneal nerve palsy in proximal tibial osteotomy

Abstract

Objectives : The level of fibular osteotomy has a role in the incidence of peroneal nerve palsy (PNP). This study aims to compare the prevalence of PNP among patients who had fibular osteotomy at two different levels. Materials and Methods: Sixty-nine limbs in fifty-two patients had valgus osteotomy of the proximal tibia and fibular osteotomy at two different levels - the proximal half (Group 1) and distal half (Group 2). The results of these were compared. Results: The incidence of peroneal nerve palsy was 23.6 and 3.2% in Groups 1 and 2, respectively ( P < 0.025). Conclusion: This study supports the choice of the distal half for fibular osteotomy.
