Distal tibial osteochondroma deforming the fibula

Three children had osteochondromata in the lateral part of the distal metaphysis of the tibia causing impingement with erosion and deformity of the fibula. The osteochondromata were removed through an anterior approach without osteotomy of the fibula. At reexamination 1.5-11 years postoperatively, the patients had normal ankle function. Remodeling of the fibula had gradually occurred in all the cases, most in the youngest patient. There was no injury to the distal tibial physis.
