Dysplasia epiphysealis hemimelica (DEH), also known as Trevor's disease, is a rare overgrowth of cartilage that commonly arises in the epiphyseal bone of children. We report a rare case of DEH originating from a talus accompanied by multiple intra-articular free bodies in a 7-year-old patient with ankle instability. After the primary surgery for free body removal and microfracture technique for the cartilage defects in the ankle joint, the free body recurred. Secondary surgery of arthroscopic free body removal with lateral ankle ligament repair succeeded in treating the patient, without further recurrence of the free body.
骨骺半侧肥大（DEH），也称为特雷弗氏病，是一种罕见的软骨过度生长疾病，常见于儿童的骨骺骨。我们报告了一例罕见的起源于距骨的DEH病例，该病例发生在一名7岁踝关节不稳定的患者身上，伴有多个关节内游离体。在首次进行游离体摘除手术以及对踝关节软骨缺损采用微骨折技术后，游离体复发。二次手术通过关节镜下摘除游离体并修复外侧踝关节韧带成功治愈了该患者，游离体未再次复发。
