Technical note—the use of an inclinometer to accurately guide intra-operative femoral de-rotational osteotomies

Abstract

Femoral de-rotational osteotomies are a safe and effective treatment for symptomatic excessive femoral anteversion or retroversion. The author’s preferred technique for performing a de-rotational osteotomy is via a subtrochanteric transverse osteotomy with intramedullary nail fixation. We describe a method for guiding femoral de-rotation correction intra-operatively using a bubble inclinometer.
