Tendon transfers are commonly used for correction of pathology or deformity of the foot and ankle. Bioabsorbable implants have been developed as an alternative to metal interference screws. The purpose of this study was to document complications following tendon transfers of the foot and ankle using bioabsorbable poly-L-lactide interference screws.
A retrospective chart review was used to identify patients in whom either of the 2 senior authors had performed a tendon transfer of the foot and ankle using a bioabsorbable interference screw between 1999 and 2005. A minimum of 6 months of follow-up was required for inclusion in the study. In all, 31 patients were identified who met the inclusion criteria with an average follow-up of 75 weeks. All screws were made of poly-L-lactide (PLLA).
Complications were identified in 12 (39%) of patients. All of the complications reported were known complications of the tendon transfer procedure itself, and were not directly related to the bioabsorbable screw.
Based on these early results, PLLA implants appear safe and effective for tendon transfers of the foot and ankle. However, until long-term outcomes are available, judicious use of these implants is recommended.
肌腱转移术常用于矫正足踝部的病理或畸形。生物可吸收植入物已被开发为金属干扰螺钉的替代品。本研究的目的是记录使用可吸收聚 L-乳酸（PLLA）干扰螺钉进行足踝肌腱转移术后的并发症。
采用回顾性图表审查的方法，确定在 1999 年至 2005 年间，两位资深作者中任意一位使用生物可吸收干扰螺钉进行足踝肌腱转移术的患者。研究纳入的标准为至少有 6 个月的随访。共有 31 名符合纳入标准的患者，平均随访 75 周。所有螺钉均由 PLLA 制成。
12 名（39%）患者出现并发症。所有报告的并发症均为肌腱转移术本身的已知并发症，与可吸收螺钉无直接关系。
根据这些早期结果，PLLA 植入物似乎安全有效，可用于足踝肌腱转移术。然而，在长期结果可用之前，建议谨慎使用这些植入物。
