Biodegradable fixation implants have been developed to avoid secondary hardware removal. The aim of this study was to retrospectively follow-up ankle fracture patients treated with a biodegradable plate and screws, and to evaluate the clinical outcome and occurrence of complications.
Fifty-seven ankle fracture patients treated with biodegradable implants were invited, and a total of 50 were available to participate in this study. The follow-up included a review of each patient's medical records, evaluation of radiographs, fracture reduction classification, and functional scoring.
There were 36 lateral malleolar and 14 bimalleolar fractures. No perioperative complications occurred. Average follow-up time was 17 months. All fractures healed. Fracture alignment was classified as anatomical in 49 patients and good in 1 case. The mean Olerud and Molander functional ankle score at final follow-up was 86. Eight patients had postoperative complications. These included delayed wound healing in 1 case, 3 cases of deep-vein thrombosis, and 4 soft tissue reactions.
According to the results of this retrospective study, the biodegradable implants used yielded fracture healing and functional results comparable to those previously reported after conventional metal fixation.
为避免二次手术取出内固定物，开发了可生物降解的固定植入物。本研究旨在回顾性随访采用可生物降解板和螺钉治疗的踝关节骨折患者，并评估其临床结果和并发症发生情况。
共邀请了 57 例采用可生物降解植入物治疗的踝关节骨折患者，其中共有 50 例患者可参与本研究。随访包括回顾每位患者的病历、评估 X 线片、骨折复位分类和功能评分。
有 36 例外踝骨折和 14 例双踝骨折。无围手术期并发症发生。平均随访时间为 17 个月。所有骨折均愈合。骨折对线在 49 例患者中被分类为解剖学，1 例为良好。最终随访时 Olerud 和 Molander 踝关节功能评分平均为 86 分。8 例患者术后出现并发症。其中包括 1 例伤口愈合延迟，3 例深静脉血栓形成和 4 例软组织反应。
根据这项回顾性研究的结果，使用可生物降解植入物可获得与传统金属固定后相似的骨折愈合和功能结果。
