OBJECTIVE To investigate the application and effectiveness of self-made spring plate in surgical treatment of acetabular posterior wall fracturejavascript:void(0)s. METHODS Between 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. RESULTS All 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. CONCLUSION For 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.

自制弹簧钢板治疗髋臼后壁骨折的应用[J].

目的探讨自制弹簧板在髋臼后壁骨折手术治疗中的应用及效果javascript:void(0)s。方法2013年6月至2017年6月收治38例髋臼后壁骨折患者。其中男27例，女11例；年龄28～68岁，平均53岁。交通事故致伤18例，其中高处坠落伤15例，摔伤5例。单纯后壁骨折4例，后壁骨折合并髋关节后脱位18例，后壁骨折合并后柱骨折10例，后壁骨折合并横行骨折6例。受伤至入院时间1~4天，平均2.5天。受伤至手术时间4~8天，平均5天。采用Kocher-Langenbeck入路（35例）或联合髂腹股沟入路（3例）骨折复位后，用弹簧板压迫后壁骨折，然后将重建板压在弹簧板上并固定在骨折端上。后柱。结果所有切口均Ⅰ期愈合。所有患者均获得随访，随访时间12～36个月，平均28个月。5例外伤后坐骨神经损伤，2例术中牵引造成坐骨神经损伤，术后3个月完全康复。影像学检查显示骨折全部愈合。骨折愈合时间10～16周，平均12周。随访期间未出现内固定断裂或失效的情况。末次随访出现股骨头坏死2例、创伤性关节炎1例、骨肌炎1例。术后12个月Harris评分，髋关节功能优27例，良5例，可2例，差4例。结论对于髋臼后壁骨折，先用弹簧板固定后壁骨折，最后用重建钢板加压弹簧板固定后柱，具有使用方便、固定可靠的优点。
