Scoliotic posture as the initial symptom in adolescents with XXXX : its curve pattern and natural history after lumbar discectomy.

@entity1 @entity1635 @entity890
BACKGROUND: There have been few studies focusing on the curve pattern of @entity1635 caused by @entity890 ( @entity890 ) in adolescents and the natural history of @entity1635 after discectomy. The current study was carried out to identify the curve pattern of @entity1635 and investigate the effect of posterior discectomy on the curve improvement in adolescents with @entity890 . METHODS: This review focused on a group of 26 adolescents with @entity890 who initially presented to our clinic for evaluation of @entity1635 , followed by posterior discectomy between 2000 and 2009. Radiographic measurements included curve pattern, specific curve features, trunk shift, and sagittal profile. The correlation between the side of disc herniation and the direction of lumbosacral curve and the trunk shift was evaluated. RESULTS: A typical curve pattern was initially identified in all of the @entity1 as a short lumbosacral curve accompanied with a long thoracic or thoracolumbar curve toward the opposite side. 23 of 26 @entity1 (88.5%) had a trunk shift more than 2.0 cm away from the midline, showing a poor coronal balance. A relatively straight sagittal profile was noted in all the @entity1 . 84.6% (22/26) @entity1 had a disc herniation at the convex side of lumbosacral curve. Similarly, 73.1% (19/26) @entity1 showed a trunk shift toward the opposite side of disc herniation. All of the @entity1 had an marked curve improvement immediately after discectomy. In the 17 @entity1 with a more than 2-year follow-up, only two had a residual lumbosacral curve greater than or equal to 20 degrees. The mean ODI improved from 21.4% before surgery to 7.3% at the final follow-up. CONCLUSIONS: A short lumbosacral curve accompanied with a long thoracic or thoracolumbar curve toward the opposite side, and a relatively straight sagittal profile have been noted in all the @entity1 . The direction of lumbosacral curve and trunk shift was related to the side of disc herniation. A majority of @entity1 have a small curve size while assosiated with a significant coronal imbalance. Earlier decompression can provide a greater opportunity for spontaneous correction of @entity1635 .
