Thirty-two patients who had pronation-lateral rotation (PLR) fractures occurring four centimeters or more proximal to the ankle joint or lower if the talus was displaced greater than one centimeter laterally were enrolled in this study. Seventeen patients were randomized to fibular plate fixation with a 4.5 ml polylactic acid (PLA) bioabsorbable syndesmotic screw, and fifteen patients randomized to fibular plate fixation with a 4.5 mm stainless steel syndesmotic screw. All thirty-two patients had uncomplicated healing of their fibular fracture without loss of reduction. There was neither evidence of osteolysis nor sterile effusion in the patients who were treated with the PLA screw. There were no wound complications in either group. No difference in range of motion or subjective complaints was noted in either group. Use of the PLA syndesmotic screw at short-term follow-up was well tolerated and avoided the need for subsequent screw removal.
32例踝关节近端4厘米或以上发生旋前-外旋（PLR）骨折的患者纳入本研究，若距骨向外移位大于1厘米，则骨折位置更低。17例患者随机接受4.5毫升聚乳酸（PLA）生物可吸收联合加压螺钉固定腓骨钢板，15例患者随机接受4.5毫米不锈钢联合加压螺钉固定腓骨钢板。所有32例患者的腓骨骨折均顺利愈合，无复位丢失。使用PLA螺钉治疗的患者既没有骨溶解的证据，也没有无菌性积液。两组均无伤口并发症。两组在活动范围或主观症状方面均未发现差异。在短期随访中，使用PLA联合加压螺钉耐受性良好，无需后续取出螺钉。
