Objective To investigate the safety and effectiveness of anatomical approach osteoligaments repair technique in treatment of pronation ankle fractures.Methods The clinical data of 53 patients with pronation ankle fractures between April 2015 and October 2016, who were treated with anatomical approach osteoligaments repair technique applied for fracture reduction and internal fixation, were analysed retrospectively. There were 35 males and 18 females with an average age of 33.1 years (range, 18-60 years). The cause of injury included traffic accidents in 27 cases, tumbling in 5 cases, fall from height in 4 cases, twisted injury in 6 cases, sports injuries in 4 cases, and bruises in 7 cases. According to Lauge-Hansen classification, there were 44 cases of pronation external rotation stage Ⅳ and 9 cases of pronation abduction stage Ⅲ. The interval between injury and operation was 4-10 days (mean, 7 days). Postoperative pain and function of ankles were assessed by American Orthopedic Foot and Ankle Score (AOFAS) and visual analogue pain scale (VAS) score. The medial clear space (MCS), tibiofibular clear space (TFCS), distal fibular tip to lateral process of talus (DFTL), the anterior and posterior tibiofibular syndesmosis distance, and the lateral malleolus twist angle were measured by X-ray films and CT of bilateral ankle joints.Results The tourniquet application time was 55-90 minutes (mean, 72.5 minutes); the frequency of fluoroscopy was 5-13 times (mean, 8.9 times). All incisions healed by first intention and no infection, deep vein thrombosis occurred after operation. All patients were followed up 28-48 months (mean, 36 months). There was no significant difference in postoperative MCS, TFCS, DFTL, the anterior and posterior tibiofibular syndesmosis distance, and the lateral malleolus twist angle between bilateral ankle joints (P>0.05). At last follow-up, no ankle instability occurred and the degenerative changes of ankle joints (Kellgren-Lawrence grading Ⅱ) occurred in 5 cases. The average AOFAS score of the ankle joint was 90.84 (range, 85-95); mean VAS score was 1.23 (range, 0-5). The average dorsiflexion and plantar flexion of ankle joints was 20.24° (range, 15-25°) and 42.56° (range, 30-50°), respectively.Conclusion Anatomical approach osteoligaments repair technique in treatment of pronation ankle fractures can expose the talocrural joint and lower tibiofibular syndesmosis clearly, repair the osteoligaments injury directly, and assist the syndesmosis and talocrural joint reduction, and decline the incidence of ankle degeneration.
