中文摘要:

目的:探讨后路单节段椎弓根螺钉内固定选择性治疗胸腰椎骨折的临床疗效。

方法:自2005年6月至2008年6月,行后路单节段椎弓根螺钉内固定治疗胸腰椎骨折28例,男17例,女11例;年龄19~60岁,平均36岁。骨折根据AO分型:A1型19例,A2型9例。观察骨折椎的椎弓根螺钉位置及手术前后骨折椎的复位情况。

结果:术后CT示骨折椎56枚椎弓根螺钉均在正常骨性结构内,均未通过骨折线。术后无脊髓损伤、感染等并发症发生。骨折椎体前缘压缩率从术前平均(42.0±5.6)%恢复至(12.4±1.4)%(P<0.05);骨折椎后凸Cobb角从术前平均(25.8±5.1)°恢复至(1.9±1.3)°(P<0.05).28例患者术后均获随访,平均18.3个月(3~36个月),骨折全部获得骨性愈合,骨折椎体高度无明显丢失,无钉棒弯曲、松动或断裂。

结论:只要手术适应证选择正确,后路单节段椎弓根螺钉内固定可用于治疗胸腰椎骨折。

Selective treatment of thoracolumbar fracture with posterior monosegmental pedicle screw fixation
ABSTRACT  

Objective: To explore the clinical effects of posterior monosegmental pedicle screw fixation in selective treatment of thoracolumbar vertebral fractures.

Methods: From June 2005 to June 2008,28 patients(male 17 and female 11,the age was 19-60 years old with an average of 36 years) with thoracolumbar fractures were treated with posterior monosegmental pedicle screw fixation in our department. According to the AO classification,19 patients with type A1 fracture and 9 with type A2. The place of pedicle screw and reduction of injured vertebral body were observed.

Results: Postoperative CT scan showed 56 pedicle screws were all placed in the normal part of injured vertebral body. There was no spinal cord injury and infection after surgery. There were restoration of anterior body compression from mean preoperative(42.0±5.6)% to(12.4±1.4)%(P<0.05),and restoration of Cobb angle from mean preoperative(25.8±5.1)° to postoperative(1.9±1.3)°(P<0.05). All the patients were followed up for 3-36 months(average in 18.3 months). All fractures achieved bone healing,without significant loss of the vertebrae body height and implant failure.

Conclusion: As indication is correctly choosed,posterior monosegmental pedicle screw fixation can be applied to treat thoracolumbar vertebral fractures.
