简介：我们对全髋关节置换术（THA）中股骨柄固定方法对假体周围股骨骨折（PFF）后续治疗的影响的理解仍然有限。本研究旨在调查和量化股骨柄固定方法的影响，即，骨水泥型与非骨水泥型THA，使用相同钢板治疗温哥华B1型假体周围股骨骨折。方法：将8个实验室人工股骨模型分为两组，分别植入骨水泥和非骨水泥髋关节假体。在解剖学单腿站立状态下测量整体刚度和应变分布。所有8个样本均接受截骨术，以模拟温哥华B1型PFF。然后使用相同的髓外钢板和螺钉固定骨折。在相同的载荷条件下进行相同的测量和断裂运动。结果：强调非骨水泥型THA和PFF固定结构的整体刚度较低。随后，非骨水泥型结构的骨折接骨板上的机械应变高于骨水泥型结构。结论：使用钢板PFF固定温哥华B1型骨折在非骨水泥型THA中可能具有更高的失败风险。
Introduction: Our understanding of the impact of the stem fixation method in total hip arthroplasty (THA) on the subsequent management of periprosthetic femoral fractures (PFF) is still limited. This study aimed to investigate and quantify the effect of the stem fixation method, i.e., cemented vs. uncemented THA, on the management of Vancouver Type B1 periprosthetic femoral fractures with the same plate. Methods: Eight laboratory models of synthetic femora were divided into two groups and implanted with either a cemented or uncemented hip prosthesis. The overall stiffness and strain distribution were measured under an anatomical one-legged stance. All eight specimens underwent an osteotomy to simulate Vancouver type B1 PFF’s. Fractures were then fixed using the same extramedullary plate and screws. The same measurements and fracture movement were taken under the same loading conditions. Results: Highlighted that the uncemented THA and PFF fixation constructs had a lower overall stiffness. Subsequently, the mechanical strain on the fracture plate for the uncemented construct was higher compared to the cemented constructs. Conclusion: PFF fixation of a Vancouver type B1 fracture using a plate may have a higher risk of failure in uncemented THAs.
