The study aimed to present the clinical results and complication rates of ring-pins with cable cerclage for treating the inferior pole of patella fracture.
A study that retrospectively reviewed consecutive patients of the displaced inferior pole of patella fracture (AO/OTA 34-A1) operated with a ring-pin tension band using cable cerclage between October 2015 and October 2017 was performed. The duration of surgery, motion range of the knee, function outcomes, and complications were recorded.
The average follow-up of 31 patients was 21 months. The mean operation time was 50 min. Fractures in all 31 patients healed at a mean duration of 8 weeks. There was no infection, no withdrawing of ring-pins, no implant breakage, and no loss of fracture reduction. The mean range of motion was 120°, and no patient complained of implant irritation at the final follow-up. The average Bostman score was 29.0 points, and 28 patients graded clinical outcomes excellent and 3 patients graded clinical outcomes good at the last follow-up.
Ring-pin combined with cable cerclage for treating the displaced inferior pole of patellar fracture is simple, and the postoperative internal fixation-related complication rate is low. It is a good choice for treating the displaced inferior pole of the patellar fracture.
本研究旨在介绍采用环形针联合缆绳环扎治疗髌骨下极骨折的临床结果及并发症发生率。
进行一项回顾性研究，纳入2015年10月至2017年10月期间采用环形针张力带联合缆绳环扎治疗的移位性髌骨下极骨折（AO/OTA 34 - A1）连续患者。记录手术时间、膝关节活动范围、功能结果及并发症情况。
31例患者平均随访21个月。平均手术时间为50分钟。31例患者骨折均在平均8周时愈合。无感染、环形针未拔出、植入物未断裂及骨折复位丢失情况。平均活动范围为120°，末次随访时无患者主诉植入物刺激。平均Bostman评分为29.0分，末次随访时28例患者临床结果评定为优，3例患者评定为良。
环形针联合缆绳环扎治疗移位性髌骨下极骨折操作简单，术后内固定相关并发症发生率低。是治疗移位性髌骨下极骨折的良好选择。
