  "abstract": "Dysplasia epiphysealis hemimelica, or Trevor disease, is a rare, nonhereditary developmental disorder characterized by benign, asymmetric osteocartilaginous epiphyseal overgrowth, predominantly involving the lower extremities and most frequently affecting the ankle joint. Surgical treatment is typically reserved for symptomatic cases, such as those with increasing pain and decreased ankle range of motion. Approaches to ankle excision include direct capsular incision and arthroscopy. These techniques can be limited by the malleoli and may result in incomplete excision of the extensive overgrowth. This paper presents our method of lateral and medial malleolar osteotomy for excision of osteocartilaginous ankle lesions in children with dysplasia epiphysealis hemimelica. We describe our surgical technique and postoperative management and compare them with alternative operative strategies reported in the literature. (1)Dysplasia epiphysealis hemimelica is a rare pediatric condition characterized by osteocartilaginous epiphyseal overgrowth that may lead to painful intraarticular lesions of the ankle joint.(2)Complete excision while preserving the articular cartilage is the primary objective of surgical treatment.(3)Lesion location and extent determine the optimal surgical approach, which may be constrained by the malleoli.(4)Malleolar osteotomy provides broad visualization of the ankle joint, facilitating excision of talar lesions.",
