Although there have been several reports describing the radiologic and clinical outcomes of pedicle subtraction osteotomy (PSO) in ankylosing spondylitis (AS) with spinal kyphotic deformity, little is known about the digestive function improvement in AS kyphosis after PSO. ⋯ The single-level or two-level PSO is an effective and safe technique to correct AS kyphosis. And the conditions of extrusion of viscera by trunk flexion decreased volume of the abdominal cavity, and abnormal visceral positions were improved by the osteotomy, followed with digestive function improvement.

Little is known about the incidence of spinal cord injury (SCI) in polytrauma patients. ⋯ Spinal cord injury with a neurologic deficit could be found in every 13th patient with polytrauma. Over half of the patients with SCI suffer from complete cord lesion. In polytrauma patients, SCI only has a limited influence on the mortality, with exception of AIS 6 lesions. Complications such as multiorgan failure or sepsis and extended hospital length of stay are more frequent in SCI.

Although stand-alone cages were advocated to be superior to plate-cage construct (PCC) because of comparable clinical outcomes and fewer plate-related complications, cage dislocation and subsidence were frequently mentioned in multilevel fusion. There are some concerns about whether these issues can be effectively prevented in multilevel anterior cervical discectomy and fusion (ACDF) by stand-alone anchored spacer (SAAS). ⋯ In the surgical treatment of three-level CSM, PCC is superior to SAAS in correction and maintenance of SA and avoiding cage subsidence, although the technique of ACDF with SAAS yielded encouraging clinical outcomes and high fusion rate.

Pedicle subtraction osteotomy (PSO) is the most commonly recommended technique for the correction of local post-traumatic thoracolumbar deformity; however, the surgical results are not always satisfactory because the possibly damaged upper disc is preserved, and all the posterior elements are resected. ⋯ The modified PSO provides an alternative method with which to correct kyphotic deformity in patients with post-traumatic thoracolumbar kyphosis.
