Abstract:
Objective:To explore the curative efficacy of pelvic reconstruction plate and T-plate elastic fixation in the treatment of acetabular fractures with comminuted posterior wall.Methods:A retrospective analysis was conducted of the 21 patients who had been treated at Department of Orthopaedics, Affiliated Hospital to the Second Mongolia Medical University for acetabular fractures with comminuted posterior wall from January 2017 to June 2019. They were 15 males and 6 females, aged from 29 to 55 years (average, 41.5 years). According to the Letournel-Judet classification, there were 15 cases of simple posterior wall fracture with dislocation of the femoral head, 4 cases of posterior wall and posterior column fracture, and 2 cases of double-column and posterior wall fracture. The time from injury to surgery averaged 3 days (from 2 to 5 days). The posterior acetabulum was treated by pelvic reconstruction plate combined with T-plate elastic fixation through the posterior acetabular Kocher-Langenbeck approach. Postoperative fracture reduction, fracture union time, function of the affected hip and complications at the last follow-up were evaluated.Results:This group of 21 patients were followed up for 6 to 24 months (average, 15 months). By the Matta imaging scoring, the postoperative reduction of the posterior wall fracture was evaluated as excellent in 18 cases and as good in 3, giving an excellent to good rate of 100%. The fracture union time averaged 10 weeks (from 8 to 12 weeks) for this group. By the improved Merle d'Aubigné & Postel evaluation at the last follow-up, the affected hips scored from 12 to 18 points (average, 16 points), yielding 18 excellent, 2 good and one poor cases, giving an excellent to good rate of 95.2%. There was no major hemorrhage, nerve injury or deep vein thrombosis intraoperatively. During the follow-up, mild ectopic ossification occurred in one case, and subluxation of the femoral head and traumatic arthritis were observed in another, but no patient had other complications like avascular necrosis of the femoral head.Conclusion:In the treatment of acetabular fracture with comminuted posterior wall, pelvic reconstruction plate and T-plate elastic fixation through the posterior acetabular Kocher-Langenbeck approach can lead to fine short-term outcomes.
