Rorabeck II型股骨假体周围骨折(PPFs)合并股骨干骨折：1例报告和综述

Rorabeck Type II Femoral Periprosthetic Fracture (PPFs) Combined with Femoral Shaft Fracture: A Case Report and Review

摘要: 随着全膝关节置换术(total knee arthroplasty, TKA)的普及，假体周围骨折已成为一个日益常见和具有挑战性的骨科问题。临床中TKA术后假体周围骨折中股骨远端骨折较为多见，但是股骨假体周围骨折合并股骨干骨折较为少见且手术复杂，在文献中很少被描述，由于骨折部位的特殊性，其诊断与治疗充满挑战性。本文介绍了1例69岁女性患者，右膝骨性关节炎行TKA术后2年，因走路不慎滑倒摔伤致右股骨假体周围骨折合并股骨干骨折，假体周围骨折分型为Rorabeck II型。手术采用闭合复位逆行髓内钉固定治疗。术后6个月随访，患者获得了完全主动的膝关节活动。此外，本文对相关文献进行了综述。

Abstract: With the increasing prevalence of total knee arthroplasty (TKA), periprosthetic fractures have become an increasingly common and challenging orthopedic issue. In clinical practice, distal femoral fractures are more frequent among post-TKA periprosthetic fractures; however, femoral periprosthetic fractures combined with femoral shaft fractures are relatively rare, surgically complex, and seldom described in the literature. Due to the specific nature of the fracture site, diagnosis and treatment present significant challenges. This article presents the case of a 69-year-old female patient who sustained a right femoral periprosthetic fracture combined with a femoral shaft fracture after a slip and fall while walking, two years post-TKA for right knee osteoarthritis. The periprosthetic fracture was classified as Rorabeck Type II. Surgical treatment involved closed reduction and retrograde intramedullary nailing fixation. At the 6-month postoperative follow-up, the patient achieved full active range of motion of the knee. Additionally, a review of the relevant literature is provided.
