Abstract: [Objective] To introduce the surgical technique and preliminary clinical results of non-parietal osteotomy for the correction of angular kyphosis of old spinal tuberculosis. [Method] Fourteen patients with old tuberculous angular kyphosis of the spine were treated with non-parietal vertebrae osteotomy. Posterior approach was used to fully expose the fixed segments and selected the vertebrae below the parietal vertebrae and close to the anatomically normal vertebrae for VCR osteotomy. Oxygen pillow was aerated to the position of bilateral thighs higher than the body, and the left vertebral pedicle titanium rod was installed, and the right temporary fixed titanium rod was released. For partial orthotic kyphosis, the right titanium rod is prebent and attached, the left titanium rod is released and the lordosis is enlarged, and this is repeated until the orthosis is satisfactory. [Results] All the 14 patients successfully completed the operation without serious complications. Follow-up was 12 months. At the last follow-up, VAS score was significantly decreased and ODI index had no significant change compared with that before surgery. The cobb Angle of sagittal plane decreased significantly after operation, and the parameters of spine and pelvis improved significantly after operation. [Conclusion] The correction of angular kyphosis of old spinal tuberculosis by non-vertebral osteotomy can significantly reduce the complications associated with surgery, shorten the operation time, reduce intraoperative bleeding, and reduce postoperative pain, and have a good orthopedic effect on kyphosis.
