Purpose

This study aimed to evaluate the outcomes of dual plating for unstable distal femoral fractures via a subgroup analysis between periprosthetic and non-periprosthetic fractures.

Methods

This retrospective cohort study analyzed the outcomes of dual plating for unstable distal femoral fractures among 49 consecutive patients (43 women and 6 men) enrolled from July 2008 to August 2020. The patients were divided into periprosthetic (group P, n = 29) and non-periprosthetic (group N, n = 20) groups. The radiographic outcomes included the mechanical lateral distal femoral angle (mLDFA) and union rate based on the computed tomography findings. The clinical parameters included the knee range of motion and knee society score (KSS).

Results

The mean patient age was 71.1 years, and the average follow-up period was 37 months (range, 12–138 months). Union was achieved in 47 patients (96%). The average final mLDFA was 90.5° in group P and 88.3° in group N. The average final knee range of motion was 130° in group P and 107° in group N. The average final KSS was 73.8 in group P and 87.1 in group N.

Conclusion

Dual plating for distal femoral fractures yielded an excellent union rate and limb alignment with a low complication rate.

双钢板治疗不稳定股骨远端骨折的结果：假体周围和非假体周围骨折的亚组比较

目的

本研究旨在通过假体周围和非假体周围骨折之间的亚组分析来评估双钢板治疗不稳定股骨远端骨折的结果。

方法

这项回顾性队列研究分析了 2008 年 7 月至 2020 年 8 月连续入组的 49 名连续患者（43 名女性和 6 名男性）中双钢板治疗不稳定股骨远端骨折的结果。患者分为假体周围（P 组，n = 29）和非假体周围。 - 假体周围（N 组，n = 20）组。影像学结果包括基于计算机断层扫描结果的股骨远端机械角 (mLDFA) 和愈合率。临床参数包括膝关节活动度和膝关节社会评分（KSS）。
