Summary
Bipolar hip arthroplasty effectively relieved pain and improved function in young patients with ankylosing spondylitis. This surgical approach demonstrated excellent outcomes, enabling patients to resume employment and enhancing hip mobility.
Area of Science:
- Orthopedics
- Rheumatology
Background:
- Ankylosing spondylitis frequently causes severe hip joint damage in young adults.
- Hip involvement significantly impairs mobility, posture, and quality of life.
Purpose of the Study:
- To evaluate the efficacy of bipolar hip arthroplasty in young patients with ankylosing spondylitis.
- To assess functional outcomes, pain relief, and range of motion following the procedure.
Main Methods:
- Nineteen hips in 12 young patients with ankylosing spondylitis underwent bipolar hip arthroplasty.
- A comprehensive postoperative rehabilitation program was implemented.
- Additional procedures like adductor tenotomy and femoral osteotomy were performed as needed.
Main Results:
- All patients experienced significant pain relief and improved posture and function.
- Mean Harris hip score improved from 27.8 to 82.6.
- Average gain in total hip range of motion was 194 degrees; no ectopic ossification occurred.
Conclusions:
- Bipolar hip arthroplasty is a suitable and effective treatment for young patients suffering from ankylosing spondylitis-related hip disease.
- The procedure leads to substantial improvements in function and quality of life, allowing return to employment.
