Short Segment Bone-on-Bone Surgical Treatment of Adolescent Idiopathic Scoliosis

· (c – DePuy AcroMed)

METHODS: The short segment bone-on-bone KASS technique was performed in ten consecutive patients with adolescent idiopathic thoracic or thoracolumbar scoliosis. The mean age was 14.4 years and the average follow up was 44 months (34 - 61 months).

RESULTS: Preoperatively, the major curve averaged 48o; this corrected to 11o postoperatively. Preoperative compensatory curves measured 34o; these spontaneously corrected to 13o postoperatively. The tilt angle correction was 70%. There was no loss of correction, no implant problems or non-unions. The average number of vertebra fused using our technique was five.
