Core Tip

Core Tip: Ankylosing spondylitis is characterized by significant hip stiffness with mobility restriction and decreased quality of life. Range of movement is reduced with coexistent flexion deformity. Total hip arthroplasty improves mobility by enhancing the quality of life. The modified Hardinge approach leaves the posterior two-thirds of the abductors intact. This approach is helpful in these hips with flexion deformity with good clinical and functional outcomes. Range of movement, Harris hip score, and quality of life indicated by the 36-item short form health survey score have shown promising results.
