A clinical and radiographic study of bipolar hip arthroplasties was performed for fractures of the femoral neck. All patients were treated with the Osteonics UHR system. Clinical results were evaluated in 77 patients (77 hips) who were observed for an average of 4.8 years (range, 2-10 years). At the latest followup, 67 (87%) patients were rated as having a good or excellent outcome according to the Hospital for Special Surgery hip rating system. Clinical ratings in patients treated with cementless UHR were similar to or better than those of patients with cemented UHR. Hip dislocation occurred in only 3 (2.3%) patients, in whom the hip joint was reduced by a closed procedure without inducing disassembly of the prosthetic components. None of the patients had definitive acetabular erosion. The motion of the outer head was evaluated radiographically in 63 patients in weightbearing and non-weightbearing conditions, 3 to 108 months after surgery. The relative motion at the 2 sites of articulation of the outer head had stabilized by 3 months after surgery and subsequently remained unchanged. The authors' findings indicate that UHR hemiarthroplasty of the femoral head is a reliable treatment for fractures of the femoral neck.
对双极髋关节置换术治疗股骨颈骨折进行了一项临床和影像学研究。所有患者均采用奥施康UHR系统进行治疗。对77例患者（77髋）进行了临床结果评估，这些患者平均观察了4.8年（范围为2至10年）。在最近一次随访时，根据特种外科医院髋关节评分系统，67例（87%）患者的结果被评为良好或优秀。非骨水泥型UHR治疗患者的临床评分与骨水泥型UHR治疗患者相似或更好。仅3例（2.3%）患者发生髋关节脱位，通过闭合手术使髋关节复位，未导致假体组件拆卸。所有患者均未出现明确的髋臼侵蚀。在术后3至108个月，对63例患者在负重和非负重情况下进行了外股骨头运动的影像学评估。外股骨头两个关节部位的相对运动在术后3个月时已稳定，随后保持不变。作者的研究结果表明，股骨头UHR半髋关节置换术是治疗股骨颈骨折的可靠方法。
