Surgical treatment for severe circumferentially fixed cervical kyphosis has been challenging. Both anterior and posterior releases are necessary to provide the cervical mobility necessary for fusion in a corrected position.
In two case reports, we describe the circumferential osteotomy of anterior-posterior-anterior surgical sequence, and the efficacy of this technique when cervical pedicle screw fixation for severe fixed cervical kyphosis is used.
Etiology of fixed cervical kyphosis was unknown in one patient and neurofibromatosis in one patient. Both patients had severe fixed cervical kyphosis as determined by cervical radiographs and underwent circumferential osteotomy and fixation via an anterior-posterior-anterior surgical sequence and correction of kyphosis by pedicle screw fixation.
Severe fixed cervical kyphosis was treated successfully by the use of circumferential osteotomy and pedicle screw fixation. The surgical sequence described in this report is a reasonable approach for severe circumferentially fixed cervical kyphosis and short segment fixation can be achieved using pedicle screws.
严重环状固定性颈椎后凸的手术治疗一直具有挑战性。为了在矫正位置实现融合所必需的颈椎活动度，需要进行前后释放。
在两例病例报告中，我们描述了前后前手术序列的环状截骨术，以及在使用严重固定性颈椎后凸的颈椎椎弓根螺钉固定时，该技术的疗效。
一名患者的固定性颈椎后凸病因不明，另一名患者为神经纤维瘤病。两名患者的颈椎 X 线片均显示严重的固定性颈椎后凸，均接受了前后前手术序列的环状截骨和固定，并通过椎弓根螺钉固定矫正后凸。
使用环状截骨和椎弓根螺钉固定成功治疗了严重的固定性颈椎后凸。本报告中描述的手术序列是治疗严重环状固定性颈椎后凸的合理方法，并且可以使用椎弓根螺钉实现短节段固定。
