Abstract：
METHODS: A 15-year-old girl known with osteogenesis imperfecta presented with left femoral pain. She had been treated with multiple Fassier-Duval intramedullary nails, which were still in situ. Radiographic imaging demonstrated focal osteolysis and periosteal reaction at the telescopic junction of the rod in the distal femur. She underwent implant removal. Intraoperative sampling demonstrating acute sterile inflammation and presence of brownish colored particles consistent with metal debris and osteolysis. Explant analysis confirmed corrosion of the stainless-steel telescopic nail as the underlying cause.
CONCLUSIONS: Osteolysis and periosteal reaction because of corrosion should be considered in conjunction with other more common causes of pain, such as fracture or infection, in patients treated with telescopic intramedullary nails.

摘要：
方法：一名15岁成骨不全症女孩出现左侧股骨疼痛。她接受了多个Fassier-Duval髓内钉治疗,它们仍然在原地。X线影像学检查显示，股骨远端杆的伸缩连接处出现局灶性骨质溶解和骨膜反应。她接受了植入物移除。术中取样显示急性无菌炎症和存在与金属碎片和骨质溶解一致的褐色颗粒。外植体分析证实不锈钢伸缩钉的腐蚀是根本原因。
结论：由于腐蚀而引起的骨溶解和骨膜反应应与其他更常见的疼痛原因一起考虑，如骨折或感染，用伸缩式髓内钉治疗的患者。
