Abstract
PURPOSE: Type 6 is an open fracture in which part of the physis is missing. It is the least common physeal fracture, but has the highest rate of complications, particularly the formation of a physeal bar. Without preemptive treatment, a physeal bar always forms, producing growth retardation and angular deformity, and excision of these physeal bars has been uniformly unsuccessful. The distal medial malleolus is a common site for the fracture.
METHODS: Strategies for the treatment of two varieties of acute medial malleolar type-6 fractures and two types of late deformities following type-6 fracture are given. The acute fractures were treated with either fat or cartilage applied to the exposed physis. The late deformities were treated with corrective iliac bone grafting.
RESULTS: The acute fractures were prevented from forming physeal bars and the two late deformities were fully corrected with good outcomes.
CONCLUSION: Fat applied to an acute type-6 physeal fracture has a good chance of preventing bar formation. Ankle deformities due to bars can be corrected by means of iliac bone grafting.
