ABSTRACT
STUDY DESIGN:
This is a retrospective study of surgical correction of thoracolumbar kyphosis caused by ankylosing spondylitis.OBJECTIVE:
To report the surgical results of thoracolumbar kyphosis deformity corrected with transpedicular wedge osteotomy performed by a single surgeon at a university hospital. SUMMARY OF BACKGROUND DATA There has not been a large series in the literature reporting on results of the Thomasen-type closing wedge osteotomy for correction of kyphosis deformity secondary to ankylosing spondylitis, nor has two-level osteotomy of this type in one patient ever been described.METHODS:
From 1991 through 1998, 92 transpedicular wedge osteotomies were performed in 78 patients with ankylosing spondylitis for correction of fixed flexion deformity of the thoracolumbar spine.RESULTS:
The mean amount of correction for each level of osteotomy was 34.5 degrees (range, 15 degrees -60 degrees ). The largest amount of overall correction for a single patient was 100 degrees. Most of the osteotomies (64 of 92) were done at L2 and L3. Fourteen patients with severe deformity required staged two-level osteotomy. Excellent and good results were obtained in 77 patients (98.7%) at the final follow-up. There was no mortality, nor were there any major neurological complications.CONCLUSIONS:
Transpedicular wedge osteotomy can effectively and safely correct kyphotic deformity of the thoracolumbar spine caused by ankylosing spondylitis, regardless of rigidity of the spinal curves. Two-level osteotomy can provide sufficient correction for severe cases.
