An adolescent obese boy showed late-onset unilateral tibia vara associated with physeal separation (slipped epiphysis) of the lateral proximal tibia and physeal widening of the lateral distal femur. These affected physes showed normal signal intensities by MRI. He was treated with lateral hemiepiphysiodesis of the left proximal tibia and the distal femur using two parallel eight-Plates, and varus deformity rapidly improved postoperatively without recurrence. This is the first case of late-onset tibia vara caused by lateral physeal separation of the proximal tibia. Normal growth of the medial physes around the knee would contribute toward significant correction after surgery.
一名青少年肥胖男孩表现为迟发性单侧胫骨内翻，伴有近端胫骨外侧骨骺分离（骨骺滑脱）及远端股骨外侧骨骺增宽。这些受累骨骺在磁共振成像（MRI）上信号强度正常。对其采用两块平行的八孔钢板对左近端胫骨和远端股骨进行外侧半骨骺阻滞术治疗，术后内翻畸形迅速改善且无复发。这是首例由近端胫骨外侧骨骺分离导致的迟发性胫骨内翻病例。膝关节周围内侧骨骺的正常生长有助于术后显著矫正。
