Multiple Osteochondromas

Large or multiple lesions in the distal leg  result in differential longitudinal growth of the tibia and fibula leading to valgus deformity of the ankle. The valgus deformity will remodel if these lesions are removed early.

Patients with osteochondromatosis present in early adulthood with valgus overload of the ankle. 

Severe ankle deformity will not remodel, and supramalleolar osteotomy may be required to correct symptomatic valgus.
