Focal fibrocartilaginous dysplasia: consideration of healing process.

We report two patients with unilateral tibia vara due to focal fibrocartilaginous dysplasia of the medial aspect of the proximal tibia. It appears that tibia vara, caused by a primary self-limited lesion at the proximal medial metaphysis, is corrected by the response of the proximal tibial physis. This finding would indicate that an infantile growth plate of the proximal tibia has a rather large potential to correct an angular deformity at the adjacent metaphysis.
