| Objective To investigate the clinical effect of lateral calcaneal transverse incision combined with bilateral distraction technique (LTBT) in the treatment of Sanders type Ⅱ and Ⅲ intra-articular calcaneal fractures.Methods From January 2016 to December 2020, 43 patients received lateral transverse incision combined with bilateral distraction technique to treat calcaneal fracture in the Second Affiliated Hospital of Anhui Medical University. The changes of calcaneus length, width, height, Bӧhler angle and Gissanes angle before operation, and 1 d, 1, 3, 6 months after operation and 1 year after operation were recorded. The perioperative data such as hospitalization time and operation time were recorded. The clinical efficacy was evaluated by VAS score and AOFAS score before operation and 1 year after operation.Results Forty-three patients were followed up for an average of (14.70±1.63) months. The length, height, width, Bӧhler angle and Gissanes angle of the calcaneus were significantly improved 1 d, 1, 3, 6 months and 1 year after operation (P<0.05). The operation time was (79.67±9.39) min. One year after operation, the VAS was (0.72±1.03) scores, and the AOFAS score was (87.14±5.42) scores. Among them, 13 were excellent, 28 were good, and 2 were normal. There was no wound complications after operation. One patient had symptoms of sural nerve injury, and two patients had pain after walking. The symptoms were improved after rest and rehabilitation therapy.Conclusion LTBT is an effective method for treating Sanders type Ⅱ and Ⅲ calcaneal fractures. In addition to providing a good surgical field and improving the effect of anatomical reduction, the length, height and width of the postoperative calcaneus, Bӧhler angle and Gissanes angle were significantly improved and well maintained in the last follow-up, while reducing the incidence of postoperative incision complications and sural nerve injury. |
