Study Design: This retrospective study was designed to evaluate treatment options for spinal stenosis with degenerative scoliosis.
Purpose: To evaluate the clinical outcomes based on the degree of spinal deformity for selective pedicle screw fixation with a long fusion for spinal stenosis with degenerative scoliosis.
Materials and Methods: We reviewed 54 cases performed from March 1996 to March 2006, and divided them into three groups based on osteophyte formation, pedicular rotation, and lateral transition. The three groups were analyzed for degree of correction of scoliotic and lordotic angle and bone fusion rate, as well as radiographically and clinically using the Kirkaldy-Willis questionnaire.
Results: Mild or moderate deformities (49 cases) were improved an average of 3 degrees of scoliotic angle, grade 1 of pedicular rotation, and 1 mm of lateral transition and were satisfied clinically. Severe deformities (5 cases) improved an average of 8 degrees of scoliotic angle, grade 2 of pedicular rotation, and 3 mm of lateral transition, but were clinically unsatisfactory. There was insignificant correction of the lordotic angle in all deformities and a fusion rate of 81.5% in mild-to-moderate deformities and 40% in severe deformities.
Conclusion: Selective pedicle screw fixation with a long fusion for spinal stenosis with degenerative scoliosis is a treatment option for mild to moderate deformities.
