METHODS: This article describes a 34-year-old male patient with early ONFH. After core decompression, he suffered a subtrochanteric fracture of the femur while bearing weight on the affected limb when going up stairs. He was subsequently treated with open reduction and intramedullary nail fixation.
CONCLUSIONS: When core decompression is used to treat ONFH, the location or size of the drill hole, whether a tantalum rod or bone is inserted, and partial weight-bearing of the affected limb may directly affect whether a fracture occurs after surgery. It is hoped that this case report can provide a reference for clinical orthopedic surgeons in the treatment of early ONFH.
方法:本文描述了一名34岁男性早期ONFH患者。堆芯减压后,他在上楼梯时承受患肢的重量时,股骨粗隆下骨折。他随后接受了切开复位和髓内钉固定治疗。
结论:当使用核心减压治疗ONFH时,钻孔的位置或大小,是否插入钽棒或骨头,患肢部分负重可能直接影响手术后是否发生骨折。希望该病例报告能为临床骨科医师治疗早期ONFH提供参考。
