Multiple osteotomies and segmental instrumentation for revision surgery in scoliosis

ABSTRACT

In this study, 20 patients who had previous surgeries performed to correct their spinal deformities were revised. The age at surgery had an average of 18 years. The dorsal curves ranged from 38-98 degrees with an average of 59.6 degrees. The lumbar curves ranged from 26-70 degrees with an average of 39.7 degrees. These patients had a double staged procedure. All patients had an anterior release performed as a first stage. On a second stage, the old implants were removed and correction was achieved by performing multiple level osteotomies in the fusion mass. The patients were re-instrumented and fusion was performed. Postoperatively, the curves were corrected to an average of 31.3 and 23.1 degrees, respectively. The patients were followed up for an average of three years. There was no postoperative neurological deficit and the complications were minimal
