From 1972 to 1984, 6 cases of dysplasia epiphysealis-hemimelica were treated in Ji-shuitan Hospital, (male/female:5/1). The medial Side of the lower extremity is more often affected(medial/lateral:6/1). The ulnar side of the upper extremity is involved in one case, which is rarely seen clnically. Different Chinese names for this condition are reviewed but the term Dysplasia Epiphysealis Hemimelica is suggested by the authors. According to its clinical features and prognosis, we suggest to divide it into 3types:knee-joint type, peritalus type and true multiple type.%@@ 半肢骨骺异样增殖是一种罕见病,国内外文献报道不多,有些病例也未及时得到正确诊断.现将我院1972～1984年收治的6例报道如下:rn病例摘要rn例1:男,4.5岁.因膝部肿物入院.体检:左下肢过长,股骨远端内侧有4×3×3cm骨性隆突,膝关节伸屈10～90°.
