Severe cervical kyphosis treated by anterior and posterior approach: case report and literature review / 中华骨科杂志

ABSTRACT

For the moment, the surgical treatment of severe rigid cervical kyphosis is still one of the difficulties in the treatment of spinal deformity. There were not consistent in the stage of correction, choice of osteotomy method, osteotomy scope and approach. In this paper, It was expected to get further understanding by sharing one case of severe cervical kyphosis treated by anterior and posterior approach, and reviewing literature. The patient was a 23-year-old female who had functional limitation due to cervical deformity for 3 years. It showed that the cervical kyphosis vertex was C 3, 4 segment, the Cobb angle was 86°, the flexibility was 8.1%, and the atlantoaxial vertebra was dislocated and unstable by the examination of X-ray, MRI, CT and CTA examination. The cervical segmental, sequence, morphological characteristics of pedicle and lateral mass, and running of the vertebral artery were also evaluated. The deformity was corrected by a one-stage operation combined anterior and posterior approaches for intervertebral and atlantoaxial release, osteotomy of the posterior lamina articular process and fusion with bone grafting. The cervical lordosis angle was recovered to 6.7°. The patients were followed up for 4 years. There were no operative and perioperative complications and we obtained satisfied surgical result.
