Is the chin-brow vertical angle always a reliable parameter for surgical planning in the correction of thoracolumbar kyphosis secondary to ankylosing spondylitis?

For AS patients with thoracolumbar kyphosis, CBVA is not consistently reliable for determining the OVA necessary for deformity correction, with its reliability closely linked to CROM. When the CROM is extensive (CROM > 20°) in patients with AS, the CBVA is not recommended as a reliable parameter for guiding the design of the OVA.

Abstract

For AS patients with thoracolumbar kyphosis, CBVA is not consistently reliable for determining the OVA necessary for deformity correction, with its reliability closely linked to CROM. When the CROM is extensive (CROM > 20°) in patients with AS, the CBVA is not recommended as a reliable parameter for guiding the design of the OVA.
