Purpose
This study was a retrospective analysis of early and mid-term clinical effects and perioperative management of cementless bilateral synchronous total hip arthroplasty (THA) in patients with ankylosing spondylitis (AS) with bilateral hip ankylosis.
Methods
Fifteen AS patients (30 hips) with bilateral hip ankylosis were managed with cementless bilateral synchronous THA. Surgical outcome was evaluated using the visual analogue scale (VAS), the range of motion and the Harris score.
Results
The mean follow-up period was 29.3 months. At the last follow-up visit, the VAS score decreased from 7.53 ± 0.99 before the operation to 2.40 ± 0.91. The Harris score increased from 24.8 ± 7.42 before the operation to 83.8 ± 4.61. The total range of motion increased from 78.73 ± 14.53 before the operation to 209.73 ± 16.19 after the operation. After the operation, there was one case of early hip dislocation, one case of femoral nerve stretch injury and one case of superficial incision infection. There were no cases of deep venous thrombosis. X-ray examinations did not show prosthetic loosening or displacement.
Conclusion
AS patients with bilateral hip ankylosis can be treated with cementless bilateral synchronous THA, which could greatly improve hip joint function without significant complications. The clinical effects proved to be satisfactory.
