Osteofibrous dysplasia treated with distraction osteogenesis: a report of two cases.

Abstract

We treated two patients with osteofibrous dysplasia of the tibia using en bloc marginal excision of the lesion and bone transport, a distraction osteogenesis procedure. In one patient, we had performed curettage procedures twice, each time followed by local recurrence and deformity. In contrast, with marginal excision and bone transport using an Ilizarov apparatus, the disease healed. In the other patient, we performed marginal excision and bone transport as the first procedure, which resulted in a healed lesion. In patients with osteofibrous dysplasia requiring treatment by an open method, curettage frequently is followed by local recurrence and deformity. We now prefer marginal excision of the lesion to avoid long-term failures, as in our first case. Distraction osteogenesis has proven useful for restoring structure and function in the affected limb.
