Abstract

Background

Nonunion after periprosthetic femoral fracture is a recalcitrant challenge for hip surgeons.

Case presentation

A 55-year-old man underwent hemiarthroplasty for right femoral head osteonecrosis at another hospital. Two weeks after surgery, he developed a periprosthetic femoral fracture. He was referred to our hospital because of nonunion of the fracture site even after five surgeries. Surgery was performed using a cementless long stem combined with a locking plate. Three locking screws were passed through the distal holes of the stem to improve fixation. Bone union was achieved, and he was able to walk six months after surgery.

Conclusions

A cementless long stem with interlocking screws inserted via a locking plate offers rigid stability and bone union. Our report is relevant because it highlights a surgical option for recalcitrant nonunion after periprosthetic femoral fractures.

使用无骨水泥长柄和通过锁定板插入的联锁螺钉成功治疗股骨假体周围骨折后的顽固性不愈合：病例报告

背景：股骨假体周围骨折后骨不连是髋关节外科医生面临的难题。一例55岁男性因右股骨头坏死在另一家医院行半关节置换术。手术后两周，他发生了股骨假体周围骨折。他被转介到我们医院，因为骨折部位不愈合，甚至在五次手术后。手术采用无骨水泥长柄结合锁定钢板。将三枚锁定螺钉穿过柄的远端孔以改善固定。手术后6个月，他就能走路了。结论无骨水泥长柄经锁定钢板置入联锁螺钉，具有良好的骨稳定性和骨愈合。我们的报告是相关的，因为它强调了手术治疗股骨假体周围骨折后顽固性骨不连的选择。
