Trevor disease (dysplasia epiphysealis hemimelica [DEH]) is a rare, intra-articular anomaly of cartilaginous overgrowth of the epiphysis. The usual presentation is on 1 side of the body and on 1 side of the epiphysis. The natural history of this disease is not clear because the lesions often are treated during childhood. Additionally, hip involvement is relatively uncommon; to our knowledge, total hip arthroplasty in a patient with DEH has not been reported previously. Our patient presented with previously untreated DEH of the hip joint, which had developed into a very unusual shape. He was treated with a total hip arthroplasty and had satisfactory functioning 2.5 years postsurgery.
Untreated DEH of the hip can lead to a very misshapen hip with a deformed femoral head and loss of the shape of the acetabulum, as well as stiffness due to an unusual shape and osteoarthritic changes. A total hip arthroplasty can give satisfactory functional results.
特雷弗病（半侧骨骺发育异常[DEH]）是一种罕见的关节内骨骺软骨过度生长异常。通常表现为身体一侧和骨骺一侧受累。由于病变常在儿童期接受治疗，该疾病的自然病程尚不清楚。此外，髋关节受累相对少见；据我们所知，此前尚未报道过DEH患者行全髋关节置换术的情况。我们的患者表现为未经治疗的髋关节DEH，已发展成非常异常的形状。他接受了全髋关节置换术，术后2.5年功能良好。
未经治疗的髋关节DEH可导致髋关节严重畸形，股骨头变形，髋臼形态丧失，以及因异常形状和骨关节炎改变而导致的僵硬。全髋关节置换术可取得满意的功能效果。
