Abstract: Introduction The principles of correction of thoracolumbar kyphotic deformity (TKLD) in ankylosing spondylitis (AS) are essentially centred on lordosing osteotomies such as pedicle subtraction closing wedge osteotomy (CWO), polysegmental posterior lumbar wedge osteotomies (PWO) and Smith Peterson's open wedge osteotomy (OWO) of the lumbar spine. There have been no studies that compared the results of the three osteotomies performed by a single surgeon with a long-term follow-up. Materials and Methods A retrosp… Show more

“…Incidence of neurological deficits has been reported to be high after PSO [25]. Neurologic deficits mainly occur from compression due to translation of a vertebral body, excessive dural kink and central canal compromise [11,26]. There were no neurologic complications in our series.…”

“…The base of the wedge includes the pedicle on the convexity with the anterior and posterior vertebral cortex making up the sides of the wedge. While it is reasonably easy to access the posterior vertebral wall, exposure of the anterior vertebral cortex poses greater challenges from posterior [4,12]. The careful dissection of the vertebral cortex with swabs (in our experience mastoid swabs worked best) across the anterior cortex allowed well-visualised resection of the anterior cortex with Kerrison rongeurs.…”
