Kim BJ, Cho SM, Hur JW, et al. - A retrospective study was performed to evaluate the risk factors for kyphosis following laminoplasty. Researchers included 53 patients diagnosed with cervical spondylotic myelopathy or ossification of the posterior longitudinal ligament who had undergone laminoplasty between May 2011 and October 2018. They obtained radiological imaging data from simple neutral and flexion-extension radiographs at baseline and at 2-year follow-up. It has been reported that kyphotic changes in the cervical spine following laminoplasty were related to preoperative radiological parameters. According to the results, the greater the preoperative extension capacity, the lower was the decrease in lordosis, and the greater the T1 slope, the greater was the decrease in lordosis.
