Pedicle Subtraction Osteotomy for the Correction of Post-tubercular Kyphotic Deformity in the Thoraco-lumbar Region: A Clinical Outcome Study
Abstract
Background: Post-tubercular kyphosis results from vertebral
collapse, instability, and canal compromise, leading to
progressive pain and neurological risk. Pedicle subtraction
osteotomy (PSO) enables single-stage correction through
wedge resection of the posterior column and pedicles with
an anterior cortical hinge.
