椎弓根螺钉内固定结合自固化硫酸钙灌注治疗胸腰椎骨折28例

Vertebroplasty with vertebral pedicle screw plus calcium sulfate cement injection treats thoracolumbar vertebrae fractures:report of 28 cases

目的探讨椎弓根钉技术结合硫酸钙灌注椎体成形治疗胸腰椎骨折的临床价值。方法对近2年多收治的28例胸腰椎骨折患者行后路椎弓根螺钉复位固定及硫酸钙人工骨灌注椎体成形手术治疗,其中A型21例,B型3例,C型4例。结果本组平均随访16个月。随访期内无内固定松动及断裂现象,无慢性腰痛,伤椎高度无丢失,注入椎体内的人工骨均在3个月内吸收。结论采用椎弓根螺钉技术复位固定及硫酸钙灌注椎体成形治疗胸腰椎骨折是一种安全、有效,术后能提供早期负重,维持良好椎体高度的较理想方法。

Objective To evaluate the clinical efficacy of vertebroplasty using vertebral pedicle screw technique combined with calcium sulfate cement injection in the treatment of thoracolumbar vertebrae fractures. Methods Twenty-eight patients with thoracolumbar vertebrae fractures admitted in our department in recent 2 years were enrolled in this study, including 21 cases of type A, 3 cases of type B, and 4 cases of type C. All patients were fixed with vertebral pedicle screw, and then verteplasty was performed using calcium sulfate cement injection. Results All patients were followed up for an average time of 16 months. Within the followup, there was no complication noted, such as loosening or breakage of internal fixation, chronical lumbar back pain, and loss of effected vertebral height. Artificial bones injected into vertebrae were absorbed in about 3 months. Conclusion Vertebroplasty using vertebral pedicle screw technique combined with calcium sulfate cement injection is an effective and safe procedure for thoracolumbar vertebrae fractures, which renders it possible to bear weight early and to maintain corrected vertebral height postoperatively.
