Abstract

Background: Femoral neck fractures in the elderly are associated with high morbidity and reduced mobility. Uncemented hydroxyapatite-coated bipolar hemiarthroplasty is increasingly used to avoid cement-related complications. This study evaluated postoperative functional outcomes using the Harris Hip Score (HHS).

Methods: A prospective observational study was conducted on 38 elderly patients (≥65 years) with displaced intracapsular femoral neck fractures who underwent uncemented hydroxyapatite-coated bipolar hemiarthroplasty. Functional outcome was assessed using the Harris Hip Score at nine months. Descriptive statistics (mean ± SD) were used.

Results: The mean Harris Hip Score at nine months was 88.4 ± 9.2. Outcomes were classified as excellent in 25 patients (66%), good in 7 (18%), fair in 4 (10%), and poor in 2 (5%). Most patients regained independent ambulation with minimal complications.

Conclusions: Uncemented hydroxyapatite-coated bipolar hemiarthroplasty provides satisfactory early functional outcomes in elderly patients with femoral neck fractures, with high HHS scores and low complication rates over nine months.

非骨水泥（羟基磷灰石包覆）双极半关节置换术治疗老年股骨颈骨折的功能效果。

背景：老年人股骨颈骨折与高发病率和活动能力降低有关。无骨水泥羟基磷灰石包覆双极半关节置换术越来越多地用于避免骨水泥相关并发症。本研究使用Harris髋关节评分（HHS）评估术后功能结局。方法：对38例老年移位型股骨颈囊内骨折患者（≥65岁）行未胶结羟基磷灰石包覆双极半关节置换术进行前瞻性观察研究。9个月时使用Harris髋关节评分评估功能结果。采用描述性统计（mean±SD）。结果：9个月Harris髋关节评分平均为88.4±9.2。25例（66%）患者的结果为优秀，7例（18%）为良好，4例（10%）为一般，2例（5%）为差。大多数患者恢复独立行走，并发症极少。结论：未胶结羟基磷灰石包覆双极半关节置换术为老年股骨颈骨折患者提供了令人满意的早期功能结果，HHS评分高，9个月内并发症发生率低。
