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.
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).
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.
Dual plating for distal femoral fractures yielded an excellent union rate and limb alignment with a low complication rate.
本研究旨在通过对假体周围和非假体周围骨折的亚组分析，评估双钢板治疗不稳定型股骨远端骨折的疗效。
本回顾性队列研究纳入了 2008 年 7 月至 2020 年 8 月期间连续收治的 49 例（43 名女性和 6 名男性）不稳定型股骨远端骨折患者，采用双钢板治疗。将患者分为假体周围组（P 组，n=29）和非假体周围组（N 组，n=20）。影像学结果包括根据 CT 检查结果测量的机械外侧股骨远端角（mLDFA）和愈合率。临床参数包括膝关节活动度和膝关节学会评分（KSS）。
患者的平均年龄为 71.1 岁，平均随访时间为 37 个月（12-138 个月）。47 例患者（96%）获得愈合。P 组平均最终 mLDFA 为 90.5°，N 组为 88.3°。P 组平均最终膝关节活动度为 130°，N 组为 107°。P 组平均最终 KSS 为 73.8，N 组为 87.1。
双钢板治疗股骨远端骨折可获得良好的愈合率和肢体对线，并发症发生率低。
