摘　　要：半肢骨骺发育异常是一种很少见的肿瘤样骨发育异常,通常好发于下肢,尤其是股骨、胫骨远端骨骺和距骨。本文报告3例,其中2例分别位于髋臼骨骺和胫骨近端前结节骨骺,实属罕见;另1例,虽见于好发部位(胫骨远端),但同时患有纤维性骨缺损,亦未见有报告。本病的诊断主要靠X线检查。其特征性的X线表现是:一侧骨骺软骨的内或外半侧过度增生和骨化中心的早出现,并且常呈多中心性骨化或钙化,最终多融合为一体而形成骨骺的偏侧肥大。主要临床表现是关节附近的无痛性肿块和轻微的膝(或踝)外(内)翻畸形。还讨论了纤维性骨缺损的有关问题。Dysplasia epiphysealis hemimelica is a very uncommon tumor—like dysplasia. Lesions are usually seen in the lower limbs; the distal epiphyses of femur and tibia and the talus are the commonest sites. Two of the three cases in our series were respectively seen in the epiphyses of the acetabulum and the tibial tuberosity, which was very rare. The third one, which showed a DEH in the distal epiphysis of tibia, was associated with a fibrous medullary defect in both proximal tibial metaphyseal regions, which has not been reported in the literatures. The diagnosis of DEH mainly depends on X—ray examination. Radiologically characteristic signs were asymmetrical overgrowth of either the lateral or the medial half of the affected epiphysis and early appearance of multicentric ossifications, which fuse later with the adjacent bone and form an epiphyseal hemihypertrophy. The main clinical features were painless bony mass and slight genu valga (or vara) deformity. Some problems about the fibrous defects of bone were also discussed.
