Three dimensional correction of adolescent idiopathic scoliosis

One hundred patients with adolescent idiopathic scoliosis had a single staged surgical procedure for correction of their deformity. The age at surgery had an average of 18y. + 5m. The dorsal curves ranged from 28° to 80° with an average of 58.1°. The lumbar curves ranged from 30° to 77° with an average of 46.7°. All patients had posterior correction, instrumentation and fusion. Postoperatively, the curves were corrected to an average of 20.3° and 18.1° respectively. Patients were followed up for an average of 3.5 years with an average loss of correction of 3.7° and 2.9° respectively. Overall, there was no postoperative neurological deficit and no metal failure. Thus, this procedure seems to be effective for correcting the deformity in all three planes

Surgical management of traumatic spondylolisthesis of the axis

Twelve patients with fractures of the neural arch of the axis [Hangman's fracture] were treated surgically by internal fixation. All patients were neurologically free preoperatively and no patient suffered from any neural deficit postoperatively. The complications were acceptable. Patients were placed in a Philadelphia Collar for 2 months and then gradually weaned of it. All patients regained a stable cervical spine

Two staged surgical correction of Scheuermann's disease

Twelve patients with Scheuermann's disease had a two-staged surgical procedure for the correction of their deformity. The age at surgery averaged 18 years + 5 months. The deformity measured an average of 86 degrees. All patients had an anterior release and fusion followed one week later by posterior correction, instrumentation and fusion. The average curve immediately after surgery was 43 degrees. The patients were followed up for an average of 3.5 years, with an average loss of correction of 4 degrees. Generally, there was no postoperative neurological deficit and no metal failure

Single stage osteotomy for congenital lumbar spine deformities

This study included 15 patients who had congenital spinal deformities due to hemi-vertebrae in the lumbar spine. The average age at surgery was 15 years. The mean preoperative Cobb angle for scoliosis was 57.7 degrees [ranged from 15-90 degrees] and that for kyphosis was 53.2 degrees [ranged from 9-118 degrees]. These patients had a single staged spinal osteotomy with posterior excision of the hemi-vertebra. The patients were instrumented and fused. Postoperatively, the index angle was 25.3 degrees, resulting in an average correction of 56% and the kyphosis was corrected to an angle of 27.9 degrees [ranged from 9-63 degrees]. The patients were followed up for an average of 28 months. There were no neurological complications and the complications were acceptable

Multiple osteotomies and segmental instrumentation for revision surgery in scoliosis

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
