To evaluate the clinical efficacies, indications and application values of posterior fusion plus pedicle screw fixation in the treatment of upper cervical spine instability.
From May 2006 to December 2010, a total of 24 patients with atlantoaxial instability were treated with C1-2 pedicle screws and rod fixation under general anesthesia. There were 18 males and 6 females with a mean age of 49.8 years old (range: 17 - 69).
The postoperative radiographs verified a good position of all screws with satisfactory atlantoaxial reduction. A mean follow-up period of 23 months (range: 3 - 45) showed no injury of spinal cord and vertebral artery or inter fixation failure. Atlantoaxial alignment and stability were restored without instrumentation-related complications.
Posterior atlantoaxial pedicle screw and rod fixation provide immediate three-dimensional rigid fixation of atlantoaxial joint. It is a more effective technique than with previously reported techniques.
评估后路融合联合椎弓根螺钉内固定治疗上颈椎不稳的临床疗效、适应证及应用价值。
2006年5月至2010年12月，对24例寰枢椎不稳患者在全身麻醉下行C1-2椎弓根螺钉及棒系统内固定术。其中男性18例，女性6例，平均年龄49.8岁（范围：17 - 69岁）。
术后X线片证实所有螺钉位置良好，寰枢椎复位满意。平均随访23个月（范围：3 - 45个月），未出现脊髓和椎动脉损伤或内固定失败。寰枢椎对线及稳定性得以恢复，未出现与内固定相关的并发症。
寰枢椎后路椎弓根螺钉及棒系统内固定可即刻提供寰枢关节的三维坚强固定。与先前报道的技术相比，该技术更为有效。
