We report a study of 168 consecutive patients (171 prostheses) with a displaced femoral neck fracture and a physiologic age older than 75 years who were treated with an uncemented bipolar Monk hard-top hemiarthroplasty. Four prostheses dislocated postoperatively, but none after discharge. Two prostheses were later extracted. Five patients sustained an ipsilateral femoral fracture. Totally, 7 patients (4 percent) were reoperated on. One year after the operation, 22 percent of the patients were dead. An increased mortality rate was recorded during the first 6 months after surgery. At follow-up 6 (3-9) years after the operation, 4 of the 62 patients alive had weight-bearing pain. Three had subsidence of the prosthesis, but none had protrusion of the acetabulum. Ninety-five percent of the patients were free from complications requiring a reoperation or outpatient evaluation.
我们报告了一项对168例连续患者（171个假体）的研究，这些患者患有股骨颈移位骨折且生理年龄超过75岁，均接受了非骨水泥型双极Monk硬顶半髋关节置换术治疗。4个假体术后发生脱位，但出院后无脱位情况。2个假体后来被取出。5例患者发生同侧股骨骨折。总共有7例患者（4%）接受了再次手术。术后1年，22%的患者死亡。术后前6个月记录到死亡率增加。在术后6（3 - 9）年的随访中，62例存活患者中有4例出现负重疼痛。3例假体下沉，但无髋臼突出。95%的患者没有需要再次手术或门诊评估的并发症。
