Abstract

Retrospective case series. To study the correction and fusion strategies for adult thoracolumbar or lumbar scoliosis with Chiari malformation and syringomyelia by using posterior pedicle screw instrumentation (PPSI). Surgical intervention for Chiari malformation and syringomyelia before surgical correction of scoliosis has been reported; however, there are no clinical trials for the PPSI-based correction and fusion procedures used in these patients. From 2002 to 2009, 13 adult patients (mean age, 34.9 years) suffering from thoracolumbar or lumbar scoliosis with Chiari malformation and syringomyelia underwent correction and fusion by using PPSI. Preoperative, postoperative, and final follow-up coronary Cobb angle, correction rate, pelvic obliquity (PO), apical vertebral rotation (AVR), apical vertebral translation (AVT), trunk shift (TS), sagittal thoracic kyphosis angle, and lumbar lordosis angle were analyzed on radiographs. The preoperative and postoperative mean coronary Cobb angle was from 46.8° to 9.2°, correction rate was 80.7%, PO from 9.9° to 3.2°, AVR from 1.9° to 0.3°, AVT from 3.6 to 0.8 cm, TS from 16.8 to 1.6 cm, sagittal thoracic kyphosis angle from 18.2° to 23.5°, and lumbar lordosis angle was from 37.4° to 41.8°...Continue Reading
