Ankylosing spondylitis with unusual spinal deformity: a case report
The Journal of Rheumatology
|November 1, 1980
Summary
Ankylosing spondylitis can lead to fixed lumbar kyphosis, a severe spinal deformity. Prolonged cycling during active inflammation may cause this posture in patients.
Area of Science:
- Rheumatology
- Spinal Disorders
- Sports Medicine
Background:
- Ankylosing spondylitis is a chronic inflammatory disease primarily affecting the spine.
- Lumbar kyphosis is an excessive outward curvature of the spine.
- Inflammatory conditions can predispose joints to deformity.
Observation:
- A case study of a 26-year-old male with ankylosing spondylitis is presented.
- The patient developed a fixed lumbar kyphosis.
- The deformity is linked to prolonged spinal flexion during bicycle riding.
Findings:
- The patient's fixed lumbar kyphosis is presumed to be caused by prolonged spinal flexion.
- This posture was adopted during a period of active inflammation in the lumbar apophyseal joints.
- Bicycle riding is identified as the activity potentially leading to the deformity.
Implications:
- Highlights a potential risk factor for spinal deformity in ankylosing spondylitis patients.
- Suggests the importance of posture and activity modification during inflammatory flares.
- Informs clinical management and patient education regarding physical activity in ankylosing spondylitis.
