Coxa magna is probably due to a period of relative hyperemia of the capial femur 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.
大髋可能是由于2至8岁期间股骨头骨骺相对充血所致。干骺端和骨骺的外周软骨因滑膜炎继发的反应性充血而增生。我们观察了11例大髋患者，并对其中5例进行了详细随访。儿童期和青春期有望获得良好功能，但随着这些患者年龄增长，可能会发生创伤性关节炎。
