目的:探讨伴骨质疏松的胸腰椎骨折脱位患者椎弓根螺钉置入技巧。方法:从2000年1月～2008年10月共收治伴骨质疏松的胸腰椎骨折脱位22例并行胸腰椎椎弓根螺钉置入内固定治疗。结果:22例患者全部置入AF钉,全部一次置钉成功,术后随访8～48个月,疗效满意。结论:椎弓根螺钉一次置钉成功是提高螺钉稳定性及治疗伴骨质疏松的胸腰椎骨折脱位成功的关键。
Objective: To explore the pedicle screw placement technique in patients with osteoporosis thoracolumbar fracture and dislocation. Methods: From January 2000 to October 2008, 22 cases of thoracolumbar fractures and dislocations with osteoporosis were treated with pedicle screw fixation of thoracolumbar spine. Results: All the 22 patients were treated with AF nail. All the patients were successfully treated with one nail. The follow-up was 8 to 48 months after operation. The curative effect was satisfactory. Conclusion: The successful pedicle screw fixation is the key to the success of screw stabilization and treatment of thoracolumbar fractures and dislocations with osteoporosis.
