A novel pre-contoured V-shaped rod in one-level pedicle subtraction osteotomy for the treatment of rigid lumbar kyphosis caused by ankylosing spondylitis: technical note and case series
One-level PSO with pre-contoured V-shaped rods at middle lumbar spine is a novel treatment option for the correction of AS-induced lumbar kyphosis and restoration of lumbar lordosis. This alternative technique obtains satisfactory radiographic and clinical outcomes for AS patients without necessitating additional surgery or elevating the risk of complications such as sagittal translation.
