Biodegradable devices have been developed to overcome the disadvantages of metallic implants especially the need for their subsequent removal, though they have their own drawbacks like poor mechanical properties and tissue reactions. Aim of this prospective study was to access the outcome of bimalleolar fractures fixed with biodegradable plates and screws.
A prospective study was conducted between July 2006 and November 2008 comprising of sixteen patients with unilateral bimalleolar fractures. Fibula fractures were fixed with biodegradable plates and medial malleoli with screws. Patients were followed at two weeks, six weeks, three months, six months, twelve months and eighteen months. Final evaluation was done using Olerud Molander ankle score.
Six patients had excellent results; four patients had good results and six patients had fair performance. No patient in this series had a poor outcome. One patient had both pain and swelling at 14 weeks postoperatively which settled down with debridement and antibiotics. None of the patients needed implant removal.
Biodegradable plates and screws when used to fix bimalleolar fracture along with restricted weight bearing, provide satisfactory fracture healing, good functional results and reduce the need of implant removal.
为了克服金属植入物的缺点，特别是需要后续取出的缺点，已经开发出可生物降解的装置，尽管它们有自己的缺点，如机械性能差和组织反应。本前瞻性研究旨在评估使用可生物降解板和螺钉固定双踝骨折的结果。
2006 年 7 月至 2008 年 11 月进行了一项前瞻性研究，共纳入 16 例单侧双踝骨折患者。腓骨骨折采用可生物降解板固定，内踝骨折采用螺钉固定。患者在 2 周、6 周、3 个月、6 个月、12 个月和 18 个月进行随访。采用 Olerud Molander 踝关节评分进行最终评估。
6 例患者结果为优；4 例患者结果为良；6 例患者结果为可。本系列中无患者结果为差。1 例患者术后 14 周出现疼痛和肿胀，经清创和抗生素治疗后缓解。无需取出植入物。
可生物降解板和螺钉固定双踝骨折，结合限制负重，可提供满意的骨折愈合、良好的功能结果，并减少植入物取出的需要。
