ABSTRACT
OBJECTIVE@#To explore the application value and clinical effect of three-dimensional printing combined with composite plate internal fixation in the treatment of old acetabular posterior wall fracture.@*METHODS@#From May 2010 to October 2016, Mimics 19.0 software was used to plan preoperatively according to a 11 print pelvic 3D model. At the same time, 23 patients with old acetabular posterior wall fractures were treated with combined plate internal fixation, including 15 males and 8 females, aged 20 to 63 (43.0±5.1) years old, and the time from injury to operation was 23 to 101(47.0±10.5) days. According to Letournel-Judet classification, 11 cases were posterior wall fracture, 7 cases were transverse with posterior wall fracture, and 5 cases were posterior column with posterior wall fracture. All patients were treated with single Kocher-Langenbeck approach combined plate internal fixation, and the evaluation indexes were recorded during operation, after operation and during follow-up.@*RESULTS@#The operation time of 23 patients was (113.5±11.5) min, bleeding was (550.0±104.7) ml and fluoroscopy was (12.7±0.8) s. Matta radiographic reduction criteria were used excellent in 14 cases, good in 7 cases and poor in 2 cases; 23 patients were followed up for 10 to 24 (16.0±5.6) months. The hip function was evaluated according to the modified Merle d'Aubingne and Postal scoring system at the last follow-up excellent in 11 cases, good in 8 cases, fair in 3 cases and poor in 1 case. There were 3 cases of traumatic arthritis, 1 case of femoral head necrosis, 2 cases of heterotopic ossification and 5 cases of sciatic nerve irritation.@*CONCLUSIONS@#3D printing technique is an effective and fast method for the treatment of old acetabular posterior wall fractures. In addition, the printing model can provide three-dimensional morphological structure for the operator, combined with preoperative simulation, facilitate intraoperative reduction, and effectively improve the efficiency of surgery.
