Introduction And Importance:
Ankylosed hips pose significant challenges due to severe joint stiffness and deformities. Total hip arthroplasty (THA) is a critical intervention that offers pain relief and improved function, despite the technical difficulties associated with altered biomechanics and preoperative deformities. This abstract highlights the complexities of THA in Ankylosing Spondylitis (AS) patients, emphasizing the need for specialized surgical approaches to optimize outcomes and mitigate the higher risk of complications.
Case Presentation:
A 20-year-old male presented with pain and severely restricted movement in the right leg, which began after a traumatic incident six years prior. Imaging studies, including plain radiographs, scanogram, and MSCT of the pelvis, revealed right hip osteoarthritis and ankylosis. The patient underwent a THA and was monitored for six months post-surgery.
Clinical Discussion:
In AS, hip involvement can lead to significant complications, including synovitis, enthesitis, avascular necrosis, and secondary osteoarthritis. Bony ankylosis, a common outcome, often results in stiffness and limited mobility rather than pain. THA is primarily indicated to address stiffness or ankylosis rather than pain in these patients. Successful THA in AS patients significantly improves quality of life but requires careful management of both intraoperative and postoperative complications.
Conclusion:
Total hip arthroplasty, whether unilateral or bilateral, offers substantial benefits for patients with AS and severe hip ankylosis. However, careful management throughout the surgical process is essential to achieve successful outcomes and improve patient quality of life.
