Fourteen patients with Lisfranc injuries were treated with open reduction and internal fixation with PLA absorbable screw fixation by a single surgeon. From one to four PLA screws were used in each case (average two). In four patients, K-wires were inserted and removed at six weeks following surgery for instability of the fourth and/or fifth tarsometatarsal joints. Average follow-up was 20 months (range, three to 45 months). No patient was noted to have a soft tissue reaction to the screws. No evidence of osteolysis was noted on any of the follow-up X-rays at the screw sites. No loss of reduction was noted in any follow-up X-rays compared to immediate postoperative radiographs. The use of absorbable screws in this small series was found to be safe, without reaction and obviated the need for screw removal at short-term follow-up.
14例Lisfranc损伤患者由同一位外科医生采用切开复位及聚乳酸（PLA）可吸收螺钉内固定治疗。每例患者使用1至4枚PLA螺钉（平均2枚）。4例患者因第四和/或第五跗跖关节不稳定，术后6周插入并取出克氏针。平均随访20个月（范围3至45个月）。未发现患者对螺钉有软组织反应。在螺钉部位的任何随访X线片上均未发现骨质溶解迹象。与术后即刻X线片相比，任何随访X线片均未发现复位丢失。在这个小样本系列中，发现使用可吸收螺钉是安全的，无反应，且在短期随访中无需取出螺钉。
