PREMATURE EPIPHYSIAL FUSION AFTER INJURY OF THE CAPITULUM

Abstract

Premature epiphysial fusion is a common complication of injury of the capitulum in childhood and sometimes results in valgus deformity. Premature fusion can either follow the normal pattern of fusion, perhaps being accelerated on the capitular side, or it can be confined to the capitulum and metaphysis. An optimistic prognosis with regard to valgus deformity and the possible onset of ulnar neuritis cannot be made in view of this complication, even in the undisplaced or perfectly reduced and immobilised cases.
