ABSTRACT
STUDY DESIGN:
A retrospective study.OBJECTIVES:
To analyze the correlation between clinical results and sagittal vertical axis, clinical results and total lumbar lordosis in degenerative lumbar scoliosis with spinal stenosis. SUMMARY OF LITERATURE REVIEW There has been no report about the relation between sagittal spinal alignment and surgical outcome of degenerative lumbar scoliosis. MATERIALS ANDMETHODS:
We reviewed 38 surgical cases of degenerative lumbar scoliosis from February 1997 to February 2001 with an average follow-up of 35 months. In whole spine standing AP and lateral radiographs, scoliotic angle(Cobb method), total lumbar lordosis(L1-S1) and the sagittal vertical axis(C7 plumb line) were measured. In lumbar flexion-extension and standing side bending views, the lateral translation was measured and instability was determined. Clinical results were evaluated based on the Kirkaldy-Willis criteria.RESULTS:
The scoliotic angles at preoperative, postoperative and follow-up were 15.0+/-4.9, 5.3+/-3.1 and 7.1+/-3.7 degrees retro-spectively. Total lumbar lordosis were 28.7+/-6.1, 40.6+/-7.3 and 35.1+/-10.2 degrees retrospectively. Sagittal vertical axis at preoperative and the last follow-up were 3.3+/-3.2 and 0.1 +/-3.3 cm retrospectively. According to Kirkaldy-Willis criteria, 6 cases were excellent, 24 cases good, 7 cases fair and 1 case poor. There was no statistical correlation between total lumbar lordosis and the clinical results (r=-0.061, p=0.717). Sagittal vertical axis was significantly correlated with the clinical results (r=0.519, p=0.001).CONCLUSIONS:
For improvement of surgical outcome of degenerative lumbar scoliosis, the sagittal vertical axis should be used as a parameter of sagittal alignment rather than the total lumbar lordosis.
