ARTICLE HIGHLIGHTS
Research background
Total hip arthroplasty (THA) with modified lateral approach has been used routinely in our unit for arthritic hips not requiring posterior wall reconstruction. A good exposure of the acetabulum with preservation of the posterior abductors is optimal for hips with flexion deformities.
Research motivation
THA with modified lateral approach is not associated with abductor compromise and results in good functional outcome as seen in individuals coming back for follow-up.
Research objectives
The objective was to have a functional and overall assessment of hips with ankylosing spondylitis at follow-up after THA. Assessment of functional outcome with described tools such as the 36-item and 12-item short form health surveys with the hip scores would provide adequate information.
Research methods
Patients with ankylosing spondylitis were assessed at follow-up after THA. Functional, clinical, and radiological assessment was done at the follow-up.
Research results
The results showed significant improvement in the functional scores in all domains with improvement in range of movement and quality of life.
Research conclusions
Modified lateral approach THA in ankylosing spondylitis improves range of movement, function, and quality of life.
Research perspectives
Long-term follow-up of 5 years to 10 years with comparison to other approaches would provide a better comparison of the efficacy of the lateral approach.
