Abstract

BACKGROUND

Femoral neck system (FNS) is an implant for patients with femoral neck fracture. It has superior angular and rotatory stability; it is less invasive because of its established locking plate system. To the best of our knowledge, there are no studies yet concerning the clinical outcomes of elderly patients with femoral neck fracture who have been treated using the FNS.

METHODS

Data of patients with femoral neck fracture aged >65 years and who had undergone internal fixation with the FNS and other implants were retrospectively analyzed in this study. The follow-up period was a minimum of six months between January 2006 and November 2020. In total, 52 patients were included in the clinical evaluations, using the FNS (group F) was 25 and using other implants (group O) was 27. Outcome measurements were surgical time, the amount of blood loss, union rate and the cases that underwent reoperation.

RESULTS

The average surgical time in the group F was 42 ± 13 min (range: 26-83 min) and was shorter than that in the group O (53 ± 21 min, range: 13-111 min, P = 0.032). The average blood loss in the group F was calculated to 36 ± 25 g (range: 0-91 g), while it was 41 ± 40 g (range: 0-169 g) in group O. No significant difference among the groups. The union rate of the group F was 100%, and the reoperation rate of the group F was significantly less than that of the group O (0% vs 22%, P = 0.023).

CONCLUSION

Internal fixation using the FNS can be an alternative option with shorter surgical time and lower reoperation rate for elderly patients with femoral neck fracture.

摘要

背景

股骨颈系统（FNS）是一种用于治疗股骨颈骨折患者的植入物。它具有优越的角度和旋转稳定性；由于其已建立的锁定板系统，它的侵袭性更小。据我们所知，目前还没有关于使用 FNS 治疗老年股骨颈骨折患者的临床结果的研究。

方法

本研究回顾性分析了 2006 年 1 月至 2020 年 11 月期间采用 FNS 和其他植入物进行内固定的年龄>65 岁股骨颈骨折患者的数据。随访时间至少为 6 个月。共对 52 例患者进行了临床评估，其中使用 FNS（F 组）为 25 例，使用其他植入物（O 组）为 27 例。测量指标包括手术时间、失血量、愈合率和再手术病例。

结果

F 组的平均手术时间为 42±13 分钟（范围：26-83 分钟），短于 O 组（53±21 分钟，范围：13-111 分钟，P=0.032）。F 组的平均失血量为 36±25 克（范围：0-91 克），而 O 组为 41±40 克（范围：0-169 克）。两组间无显著差异。F 组的愈合率为 100%，F 组的再手术率明显低于 O 组（0% vs 22%，P=0.023）。
