Functional outcome after lumbar closing wedge osteotomy in ankylosing spondylitis.
This study entails a prospective evaluation of lumbar closing wedge osteotomy for correction of thoracolumbar kyphotic deformity in ankylosing spondylitis. Twenty patients with a median age of 52 years (range, 26-70) underwent follow-up at one year. The lumbar closing wedge osteomtomy was stabilised by metallic rods fixed by transpedicular screws. Outcome measures were quality of life (EuroQol), occiput-to-wall distance, pain, fatigue, complications, technical and radiological evaluation. The technical result was good in 16 and fair in four patients; two had neuropraxia. The deformity was reduced an average of 17 degrees (95% confidence interval 15-25 degrees) at one-year follow-up. Pain during activity, pain at night, and fatigue were significantly reduced. EuroQol improved from 0.42 to 0.69 (p = 0.002) and occiput-to-wall distance from 26 to 18 cm (p = 0.005). Functional outcome was improved after lumbar closing wedge osteotomy in ankylosing spondylitis.
