Capital femoral physeal fractures occurred simultaneously in twin 2-year-old Shropshire ewes. The fractures resulted in gradual, progressive lameness and recumbency. There was no history of trauma and no other ewes in the flock were affected. The fractures occurred at an age when the capital physis should have been closed. Clinical and postmortem examination of the ewes and evaluation of the ration did not reveal predisposing factors for the condition. A familial tendency for fractured capital femoral epiphysis is well documented in human beings, but there is no known familial tendency in sheep.
双侧股骨近端骨骺骨折同时发生在两只2岁的什罗普郡母羊身上。骨折导致逐渐加重的跛行和卧地不起。无外伤史，羊群中其他母羊未受影响。骨折发生在股骨近端骨骺本应闭合的年龄。对母羊进行临床和尸体剖检以及对日粮进行评估，均未发现该病的诱发因素。人类中股骨近端骨骺骨折的家族倾向已有充分记录，但绵羊中尚无已知的家族倾向。
