To report outcome of 30 patients who underwent bipolar hemiarthroplasty for intracapsular femoral neck fractures.
18 women and 12 men aged 56 to 86 (mean, 70) years with Garden type III (n=7) or IV (n=23) intracapsular femoral neck fractures underwent cemented (n=5) or uncemented (n=25) bipolar hemiarthroplasty. Pain was evaluated using the visual analogue score. Mobility status was classified as ambulation with or without aid (a cane or walker). Stability of the prosthesis was classified as stable or unstable. Functional outcome was evaluated using the Harris Hip Score.
The mean length of hospital stay was 15.3 (range, 4-29) days. At the 6-month follow-up, 21 patients had no pain, 6 had mild pain, and 3 had moderate pain. The mean Harris Hip Score was 83.1; functional outcome was excellent in 10 patients, good in 13, fair in 5, and poor in 2. The latter 2 were non-ambulatory; one of whom had sustained a periprosthetic fracture intra-operatively, which was managed by encerclage wiring, and the other had a neglected prosthetic dislocation at 3 months, which was converted to an excision arthroplasty.
Bipolar hemiarthroplasty conferred good short-term outcome.
报告30例因囊内股骨颈骨折接受双极半髋关节置换术患者的治疗结果。
18例女性和12例男性，年龄56至86岁（平均70岁），患有Garden III型（n = 7）或IV型（n = 23）囊内股骨颈骨折，接受了骨水泥型（n = 5）或非骨水泥型（n = 25）双极半髋关节置换术。使用视觉模拟评分法评估疼痛情况。活动状态分为需辅助（使用手杖或助行器）或无需辅助行走。假体稳定性分为稳定或不稳定。使用Harris髋关节评分评估功能结果。
平均住院时间为15.3天（范围4 - 29天）。在6个月随访时，21例患者无疼痛，6例有轻度疼痛，3例有中度疼痛。Harris髋关节评分平均为83.1分；10例患者功能结果为优，13例为良，5例为中，2例为差。后2例不能行走；其中1例术中发生假体周围骨折，采用钢丝环扎处理，另1例在3个月时发生假体脱位未得到及时处理，改行关节切除成形术。
双极半髋关节置换术短期效果良好。
