From Looking at the Floor to Looking Forward: A Case of Hyperkyphotic Spine in an Ankylosing Spondylitis Patient.

Ankylosing spondylitis (AS) is a chronic inflammatory disorder characterized by progressive spinal stiffness and deformity, primarily affecting the sacroiliac joints, spine, and pelvis. In advanced cases, untreated AS can lead to severe kyphosis, resulting in debilitating functional impairment and a significantly reduced quality of life. We present a case of a patient with a fixed thoracolumbar kyphotic deformity that severely affected his daily function.
