Summary
Bilateral total hip replacement (THR) effectively treats ankylosed hip joints in late ankylosing spondylitis (AS) patients. This surgery improves joint function and relieves pain, but requires careful pre- and postoperative management.
Area of Science:
- Orthopedic Surgery
- Rheumatology
- Medical Engineering
Background:
- Ankylosing spondylitis (AS) can lead to severe hip joint ankylosis.
- Hip joint fusion significantly impairs mobility and quality of life.
- Late-stage AS often necessitates surgical intervention for functional restoration.
Purpose of the Study:
- To evaluate the efficacy of bilateral total hip replacement (THR) in patients with AS-induced hip ankylosis.
- To analyze functional outcomes and pain relief following simultaneous bilateral THR.
- To identify and discuss critical pre- and postoperative considerations for this patient cohort.
Main Methods:
- Retrospective review of 12 patients (24 hips) with AS-related hip ankylosis undergoing simultaneous bilateral THR.
- Assessment of postoperative joint pain, range of motion (ROM), and Harris Hip Score (HHS).
- Data analysis focused on functional improvement and complication avoidance.
Main Results:
- Significant improvement in hip joint function and correction of flexion deformity observed post-THR.
- Average flexion ROM improved to 84.4° (75-105°), with extension averaging 18.7° (10-20°).
- Harris Hip Score improved from a mean of 15.21 preoperatively to 86.25 postoperatively; all patients reported pain relief.
Conclusions:
- Bilateral THR is a highly effective surgical option for managing ankylosed hip joints in late AS.
- The procedure leads to substantial improvements in joint function, mobility, and pain reduction.
- Careful attention to pre- and postoperative management is crucial for optimal outcomes in AS patients undergoing bilateral THR.
