Single stage osteotomy for congenital lumbar spine deformities

ABSTRACT

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
