Eligibility

Inclusion criteria

Inclusion criteria: 1. All Patients with bilateral fused hips (complete loss of movement and, x-rays showing complete loss of joint space and trabeculae passing from the acetabulum to the head of the femur due to Ankylosing Spondylitis requiring Total Hip Arthroplasty 2. Patients giving consent for the study

Exclusion criteria

Exclusion criteria: 1. Unilateral fused hip 2. Surgically arthrodesed hips 3. Fused hips due to heterotrophic ossification 4. Previous history of any surgery to the hips 5. One fused hip and hip replacement prosthesis in the other 6. Refusal to participate in the study

Design outcomes

Primary

MeasureTime frame
To compare the clinicoradiological outcomes in patients with Ankylosing Spondylitis with fused hips and spinopelvic deformity undergoing total hip arthroplasty using a novel computer assisted design (CAD) model based protocol vs. conventional techniqueTimepoint: 3 months—

Secondary

MeasureTime frame
1.To evaluate the spinopelvic deformity in patients with bilateral fused hips in Ankylosing Spondylitis 2.To evaluate the possible impact of hip arthroplasty on pelvifemoral parameters once the patient is upright and mobile with still persistent pelvifemoral deformity 3.To evaluate the possible impact of spinopelvic deformity on the spatial orientation of the components of Total Hip Arthroplasty.Timepoint: 2 years—
