A prospective outcome study was performed on 270 patients, 65 years of age and older, who sustained a femoral neck fracture and underwent hemiarthroplasty. The treatment compared was the use of a noncemented unipolar versus either a cemented or a press fit bipolar prosthesis. The outcome variables assessed included the occurrence of a postoperative complication, length and cost of hospitalization, and function in various quality of life measurements. Patients who underwent bipolar hemiarthroplasty with either a cemented or a press fit prosthesis had better pain relief and function than patients who had a noncemented unipolar prosthesis at a minimum of 24 months after surgery. However, the mean hospitalization cost for patients who had a bipolar prosthesis was $12,290 compared with $8876 for a unipolar prosthesis.
对270名65岁及以上的股骨颈骨折并接受半髋关节置换术的患者进行了一项前瞻性结局研究。比较的治疗方法是使用非骨水泥单极假体与骨水泥或压配双极假体。评估的结局变量包括术后并发症的发生情况、住院时间和费用，以及各种生活质量测量中的功能。接受骨水泥或压配双极假体半髋关节置换术的患者在术后至少24个月时，疼痛缓解和功能方面比使用非骨水泥单极假体的患者更好。然而，使用双极假体的患者平均住院费用为12290美元，而单极假体患者为8876美元。
