  • APPLICATION OF ACETABULAR TRIDIMENSIONAL MEMORY ALLOY-FIXATION SYSTEM IN TREATMENT OF OLD ACETABULAR POSTERIOR WALL FRACTURE WITH BONE DEFECT

    Objective To investigate the effectiveness of acetabular tridimensional memory alloy-fixation system (ATMFS) combined with autologous il iac bone in the treatment of old acetabular posterior wall fracture with bone defect. Methods Between January 2002 and February 2009, 17 patients with old acetabular posterior wall fracture and bone defect were treated, including 11 males and 6 females with an average age of 41.7 years (range,20-60 years). The time from fracture to admission was 14-180 days (mean, 63 days). The displacement of the acetabular articular surface was more than or equal to 3 mm. According to the America Association of Orthopedic Surgeon (AAOS) acetabular fracture and defectclassification standard, there were 4 cases of type I, 6 cases of type II, 5 cases of type III, and 2 cases of type IV. After the residual fracture fragments of the acetabular posterior wall and soft tissue hyperplasia were removed, the femoral head was reducted, and posterior wall defect was repaired with autologous il iac bone graft; ATMFS was used to fix acetabular posterior wall and artificial capsular l igament to reconstruct the hip so as to prevent re-dislocation of the femoral head. Results According to Matta imaging assessment standard, the results were excellent in 8 cases, good in 6 cases, fair in 2 cases, and poor in 1 case with an excellent and good rate of 82.3%. All incisions healed by first intention, and no sciatic nerve injury occurred. All patients were followed up 1-8 years (mean, 3.9 years). The mean time of fracture union was 3.6 months (range, 2-6 months). Avascular necrosis of femoral head occurred in 1 case, heterotopic ossification around the acetabulum in 1 case. According to Merle d’ Aubigné-Postel scoring system evaluation, the cl inical results were excellent in 9 cases, good in 6 cases, fair in 1 case, and poor in 1 case with an excellent and good rate of 88.2%. Conclusion ATMFS combined with autologous il iac bone graft and artificial l igament reconstruction of the hip joint capsule is a good choice for the treatment of old acetabular posterior wall fractures with bone defect, which can resume the posterior hip joint stabil ity and prevent re-dislocation of the femoral head.

  • Application of self-made spring plate for treatment of acetabular posterior wall fractures

    ObjectiveTo investigate the application and effectiveness of self-made spring plate in surgical treatment of acetabular posterior wall fracturejavascript:void(0)s.MethodsBetween June 2013 and June 2017, 38 patients with acetabular posterior wall fractures were treated. There were 27 males and 11 females with an average age of 53 years (range, 28-68 years). The injury caused by traffic accident in 18 cases, falling from height in 15 cases, and tumble in 5 cases. There were 4 cases of simple posterior wall fracture, 18 cases of posterior wall fracture with posterior dislocation of hip joint, 10 cases of posterior wall fracture with posterior column fracture, and 6 cases of posterior wall fracture with transverse fracture. The time from injury to admission was 1-4 days (mean, 2.5 days). The time from injury to operation was 4-8 days (mean, 5 days). After fracture reduction via the Kocher-Langenbeck approach (35 cases) or the combined ilioinguinal approach (3 cases), the spring plate was used to press the posterior wall fracture, and then the reconstruction plate was pressed against the spring plate and fixed to the posterior column.ResultsAll the incisions healed by first intention. All patients were followed up 12-36 months (mean, 28 months). Five cases of post-traumatic sciatic nerve injury and 2 cases of sciatic nerve injury caused by traction during operation were fully recovered at 3 months after operation. The imaging examination showed that all the fractures healed. The fracture healing time was 10-16 weeks (mean, 12 weeks). There was no ruptures or failures of internal fixation during the follow-up period. There were 2 cases of femoral head necrosis, 1 case of traumatic arthritis, and 1 case of osteomyositis at last follow-up. The hip joint function was rated as excellent in 27 cases, good in 5 cases, fair in 2 cases, and poor in 4 cases according to the Harris scores at 12 months after operation.ConclusionFor the acetabular posterior wall fracture, it has the advantages of easy to use and reliable fixation that the posterior wall fracture is fixed with spring plate firstly, and the spring plate is pressed to fix the posterior column with the reconstruction plate finally.

  • Application of new H-shaped anatomical titanium plate for posterior wall/posterior column acetabular fractures

    ObjectiveTo explore the effectiveness of a new H-shaped anatomical titanium plate in treatment of posterior wall/posterior column acetabular fractures.MethodsBetween March 2012 and April 2019, 46 patients with acetabular fractures involving posterior wall/posterior column were treated with the new H-shaped anatomical titanium plates. There were 28 males and 18 females. The age ranged from 20 to 70 years, with an average of 45.5 years. Among the patients, 34 cases were injured by traffic accidents and 12 cases by falling from height. The time from injury to operation ranged from 2 to 14 days, with an average of 7 days. According to Letournel-Judet classification, there were 12 cases of posterior wall fractures, 1 case of posterior column fracture, 3 cases of transverse fractures, 9 cases of transverse fractures involving posterior walls, 8 cases of posterior column and posterior wall fractures, 2 cases of anterior column and posterior semi-transverse fractures, 3 cases of T-shaped fractures, and 8 cases of double column fractures. Matta reduction standard was used to evaluate fracture reduction and Merle d’Aubign-Postel score was used to evaluate hip joint function.ResultsAll operations were successfully completed. The time of posterior operation was 60-120 minutes, with an average of 80 minutes. The amount of intraoperative blood loss ranged from 200 to 600 mL, with an average of 300 mL. All the incisions healed by first intention and no infection, deep vein thrombosis, or sciatic nerve injury occurred. All 46 patients were followed up 6-72 months, with an average of 37 months. According to Matta reduction standard, 40 cases obtained anatomic reduction, 4 cases satisfactory reduction, 2 cases unsatisfactory reduction, and the satisfaction rate was 95.7% (44/46). All fractures healed, and the healing time was 3-6 months, with an average of 4.3 months. No internal fixation failure occurred during the follow-up. At last follow-up, the Merle d’Aubign-Postel score ranged from 6 to 18 (mean, 15.5), including 38 cases of excellent, 4 cases of good, 2 cases of fair, and 2 cases of poor, with an excellent and good rate of 91.3% (42/46). Heterotopic ossification occurred in 4 cases, traumatic arthritis in 4 cases, and osteonecrosis of femoral head in 2 cases after operation.ConclusionFor acetabular fractures involving posterior wall/posterior column, the new H-shaped anatomical titanium plate can provide stable fixation, satisfactory reduction, and good recovery of hip function.
