Abstract:
Objective:To observe the clinical effect of retrograde distal tibial intramedullary nail fixation in the treatment of proximal ankle fracture of the distal tibia.Methods:A three-dimensional CT examination of 40 adult tibias was performed to measure anatomical indicators such as the posterior medial posterior torsion angle of the distal tibia, the height of torsion, and the height of the safety zone for nail placement. Based on the anatomy database of the human skeleton model, a retrograde distal tibial nail and its supporting instruments were developed in accordance with the anatomical characteristics of the distal tibia and the proximal ankle of Chinese people. From June 2019 to June 2023, a total of 25 patients with distal tibial proximal ankle fractures treated with retrograde intramedullary nail internal fixation in the 909th Hospital were retrospectively analyzed. There were 18 males and 7 females, aged 41.3±10.8 years (range, 22-65 years). The sample size was 1∶1 matched according to gender and age. Twenty-five patients with distal tibial proximal ankle fractures who underwent antegrade intramedullary nail fixation during the same period were matched, including 20 males and 5 females, aged 41.2±9.4 years (range 19-60 years). The reduction quality, postoperative Baird-Jackson score, American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score, ankle range of motion and complications were observed.Results:All patients were successfully operated and followed up for 14.4±3.5 months (range, 12-24 months). The intraoperative blood loss and hospitalization time in retrograde intramedullary nail group were 33.12±7.38 ml and 10.32±1.75 d, less than 49.04±10.22 ml and 13.16±2.69 d in antegrade intramedullary nail group, and the difference was statistically significant ( P<0.05). The reduction quality was excellent in 23 cases and good in 2 cases in the retrograde intramedullary nail group, and was excellent in 17 cases and good in 8 cases in the anterograde intramedullary nail group. The proportion of excellent reduction quality in the retrograde intramedullary nail group was higher than that in the anterograde intramedullary nail group, and the difference was statistically significant (χ 2=4.500, P=0.034). The Baird-Jackson score and AOFAS ankle and hindfoot score in the retrograde intramedullary nail group were 85.6±2.5 and 85.8±3.3 at 3 months after operation, lower than those at 1 year after operation 95.3±3.1 and 95.8±3.6, and the difference was statistically significant ( P<0.05). The Baird-Jackson score and AOFAS ankle and hindfoot score of the antegrade intramedullary nail group were 85.1±3.3 and 86.1±2.5 at 3 months after operation, lower than 95.2±2.7 and 94.9±3.5 at 1 year after operation, and the difference was statistically significant ( P<0.05). There was no significant difference in Baird-Jackson score and AOFAS ankle and hindfoot score between the two groups at 3 months and 1 year after operation ( P>0.05). At the last follow-up, there was no ankle stiffness, neurovascular injury, deep vein thrombosis, infection or breakage of internal fixation in the two groups. Conclusion:The treatment of distal tibial proximal ankle fractures with retrograde intramedullary nail fixation has satisfactory reduction quality, good postoperative function recovery, and is helpful for early postoperative rehabilitation.
