Coxa Magna

Authors: JOHN A. POWERS MD, PHILIP J. BACH MD

Abstract

Coxa magna is probably due to a period of relative hyperemia of the capital femoral epiphysis between 2 and 8 years of age. The peripheral cartilage of the metaphysis and epiphysis proliferate as a response to reactive hyperemia secondary to synovitis. We have observed 11 patients with coxa magna and have followed five in detail. Good function is expected in childhood and adolescence, but traumatic arthritis will probably occur as these patients get older.
