Core Tip
Core Tip: Progressive spine stiffness associated with stiff hips in ankylosing spondylitis (AS) results in mobility restriction and reduces the quality of life in young individuals. Preoperative planning for total hip arthroplasty (THA) in AS requires spinopelvic mobility assessment. Sacral slope change is reduced (< 10 degrees) with a predominant stuck sitting pattern and posterior pelvic tilt. Care needs to be exercised to reduce acetabular anteversion preventing posterior impingement and anterior dislocation. Risks at THA in AS include intraoperative fractures, postop dislocation (1.9%), heterotopic ossification, among others, with revision-free survivorship of 82% at 20 years. Significant functional and mobility improvement justifies THA in AS with stiff hips and spine.
