This preliminary study introduces a novel surgical technique for short-term fixation of greater trochanter fractures, in periprosthetic fractures, using nonabsorbable sutures and a metal cable, supported by a case series of 6 patients. The technique employs a 1.8-mm cable and 3 #5 nonabsorbable sutures, anchored through the trochanter and secured at the abductor tendon, with sequential tying to ensure stability. Among the 6 patients (mean age 77.3 ± 9.2 years), all demonstrated callus formation of the trochanteric fragment at final follow-up, with minimal migration relative to initial postoperative imaging (mean 2.1 ± 2.3 mm). At follow-up, ambulatory status included: 2 patients using walkers, 1 wheelchair-bound (preoperatively), and 3 ambulating independently. These outcomes suggest that this technique reduces hardware reliance and improves load distribution, promoting functional recovery.
这项初步研究介绍了一种用于大转子骨折短期固定的新型手术技术，该技术用于假体周围骨折，采用不可吸收缝线和金属缆线，并以6例患者的病例系列为支撑。该技术使用一根1.8毫米的缆线和3根5号不可吸收缝线，通过转子进行锚定并固定在外展肌腱处，通过顺序打结来确保稳定性。在这6例患者（平均年龄77.3±9.2岁）中，所有患者在最终随访时均显示转子碎片有骨痂形成，相对于术后初始影像，移位极小（平均2.1±2.3毫米）。在随访时，活动状态包括：2例患者使用助行器，1例（术前）依赖轮椅，3例可独立行走。这些结果表明，该技术减少了对硬件的依赖，改善了负荷分布，促进了功能恢复。
