Summary
Total hip arthroplasty effectively relieved pain and improved walking in ankylosing spondylitis patients. Range of motion gains were limited by myositis ossificans and contractures.
Area of Science:
- Orthopedic Surgery
- Rheumatology
- Arthroplasty
Background:
- Ankylosing spondylitis frequently causes hip joint damage.
- Total hip arthroplasty is a treatment option for severe hip involvement.
Purpose of the Study:
- To evaluate the outcomes of total hip arthroplasty in patients with ankylosing spondylitis.
- To identify factors affecting range of motion post-surgery.
Main Methods:
- Retrospective analysis of 29 total hip arthroplasties in 19 ankylosing spondylitis patients.
- Average follow-up of over four years.
Main Results:
- 97% of patients achieved complete pain relief.
- Significant improvements in ambulatory capacity were observed.
- Average range of motion improvement was 75 degrees.
Conclusions:
- Total hip arthroplasty provides substantial pain relief and functional improvement for ankylosing spondylitis.
- Myositis ossificans (23% incidence) and contractures limit range of motion gains.
