Unilateral femoral angulation is uncommon. We describe two children with unilateral progressive distal femoral varus and limb-length discrepancy. These deformities were associated with a fibrous lesion involving the medial aspect of the distal femoral metaphysis. Both patients were 15 to 16 months old. In both, the deformity was progressive, resulting in excisional biopsy and osteotomy. The gross and microscopic appearance of both lesions was similar, and the histology was dense fibrous connective tissue. The patients' femoral alignment was maintained at follow-up of a minimum of 16-36 months. The etiology of these lesions is unknown; they are associated with progressive deformity and appear to respond well to surgical intervention.
单侧股骨成角并不常见。我们描述了两名患有单侧进行性股骨远端内翻和肢体长度差异的儿童。这些畸形与累及股骨远端干骺端内侧的纤维性病变有关。两名患者均为15至16个月大。两人的畸形均呈进行性发展，最终进行了切除活检和截骨术。两个病变的大体和显微镜下表现相似，组织学为致密纤维结缔组织。在至少16至36个月的随访中，患者的股骨对线得以维持。这些病变的病因尚不清楚；它们与进行性畸形相关，并且似乎对手术干预反应良好。
