Objectives

To investigate the mortality rate for neck of femur fractures treated with arthroplasty at a tertiary level unit in South Africa and to evaluate the effect of known risk factors for mortality in neck of femur fractures treated with arthroplasty in the South African context.

Design

Retrospective cohort study. The main outcome was to determine mortality rates during in hospital stay, at 3 months, 6 months 1 year post surgery. The secondary outcome was to determine factors influencing mortality at 30 days, 6 months and 12 months post-surgery.

Results

Mortality rate was 3.3% in hospital, 5.6% at 30 days and 26.7% at 1 year. Age >79, ASA score >3, and cementing of the femur had statistically increased mortality risk (P < .001). Average length of hospital stay was 12.3 ± 5.1 days (range 3.0-41.0 days) with 73% of patients discharged back to pre-hospital home.

Conclusion

Mortality rates after femur neck fracture arthroplasty in South Africa are slightly higher at 1 year compared to international data. However, the rates are comparably low during hospital stay, 30 day and at 6 months post-surgical intervals.

南非关节置换术治疗股骨颈骨折的死亡率

目标

调查南非三级单位股骨颈骨折接受关节置换术治疗的死亡率，并评估已知风险因素对南非关节置换术治疗股骨颈骨折死亡率的影响。

设计

回顾性队列研究。主要结果是确定住院期间、术后 3 个月、6 个月和 1 年的死亡率。次要结果是确定影响术后 30 天、6 个月和 12 个月死亡率的因素。

结果

住院死亡率为 3.3%，30 天时为 5.6%，1 年时为 26.7%。年龄 >79 岁、ASA 评分 >3 和股骨骨水泥在统计学上增加了死亡风险（P < .001）。平均住院时间为 12.3 ± 5.1 天（范围 3.0-41.0 天），73% 的患者出院返回院前家中。

结论

与国际数据相比，南非股骨颈骨折关节置换术后 1 年的死亡率略高。然而，住院期间、手术后 30 天和 6 个月的比率相对较低。
