Abstract
Objective: To assess early results with the KASS system for scoliosis correction. To assess lateral curvature, rotational correction and complications.
Design: The first 22 patients requiring anterior correction of scoliotic curves were retrospectively reviewed. Pre- and post-operative curve measurements were made with a Cobbometer. Topographical assessment (ISIS) scan was used to assess rotation and correction of the rib hump. The notes were reviewed to determine complications and time to discharge.
Subjects: Twenty-two patients: 18 idiopathic scoliosis (4 others); average age 15.4 years; 5 King One, 10 King Two, 6 King Three and one non-definable; 5 thoracic curves
Results: Average pre-op scoliosis 54.85 degrees
Average post-op scoliosis 19.4 degrees. Average correction 65%. One patient required second operation for long screws. Four self limiting rninor complications. Average time to discharge eight days
Conclusion: KASS instrurnentation is a safe, effective and reliable method to correct scoliotic curves including rotational deformities. It was not possible to correct the Cobb angle of purely thoracic curves as much as thoracolumbar curves. Cosmetic correction however has been excellent as demonstrated with ISIS. Long term review will be necessary to confirm that correction is maintained.
