Abstract:PurposeDerotational distal femoral osteotomy (DFO) is the causal treatment for patients with femoral torsional deformity. The fixation is achieved by a unilateral angle‐stable plate. Delayed‐ or non‐unions are one of the main risks of the procedure. An additional contralateral fixation may benefit the outcome. Therefore, we hypothesize that primary stability in DFO can be improved by an additional fixation with a hinge screw or an internal plate.MethodsDerotational DFO was performed in 15 knees and fixed eithe… Show more
