Fibular rotational osteotomy for the treatment of distal tibial osteochondroma: a technical modification for deformity correction and improved outcomes.

Abstract

The technique of choice for excision of osteochondromas located in the lateral aspect of the tibia is a transfibular approach to expose the lesion for resection. A drawback of this approach is that removal of the lesion leaves a void that may cause a visible deformity and adversely affect long-term function. Fibular rotational osteotomy followed by fibular graft may minimize the resultant deformity, producing a more satisfactory functional and cosmetic result. The authors report a retrospective case series consisting of 5 cases in which a fibular graft rotation was performed after rotational osteotomy via a transfibular approach. Retrograde intramedullary fixation by means of a Kirschner wire, in combination with the design of the fibular osteotomy, provided rotational graft and fibular stability until healing occurred.
