Résumé
OBJECTIVE: Evaluate the results of the posterior instrumentation for the correction of adolescent idiopathic scoliosis (AIS) in Lerdsin Hospital. MATERIAL AND METHOD: A retrospective study was conducted to determine the effectiveness of surgical treatment of idiopathic scoliosis in Lerdsin Hospital. The pre-operative, immediate post operative, and the most recent follow-up (minimum 2 years) x-ray of 17 patients were evaluated for curve correction and spinal balance. RESULT: The present study found that the curvatures in thoracic King type II and III were corrected by about 58% post operatively. The curve progressed 3 degrees (5%) at the end of 2 years. For lumbar curve in King types I and II, there was the correction of 51% and 59%. After 2 years, the curve progressed around 6 degrees (7%) and 8 degrees (14%). Trunk balance was corrected by 60% in King type III. Degrees of thoracic kyphosis was decreased about 4 degrees. CONCLUSION: Frontal and sagittal thoracic and lumbar curve correction can be satisfactorily obtained by posterior spinal correction with instrumentation.

SUMMARY OF BACKGROUND DATA: The association between the facet tropism and the development of lumbar disc herniation has been studied; however the results remain controversial. OBJECTIVE: To determine the association between the facet tropism and the development of lumbar disc herniation. STUDY DESIGN: A cross-sectional study. MATERIAL AND METHOD: MRI of 34 patients with lumbar disc herniation was evaluated. Two orthopedic surgeons measured facet joint angle and determined the degenerative status of L3-4, L4-5, and L5-SI. Facet tropism was defined as the difference between the angle of the right and left facet more than 5 degrees. RESULTS: The average difference of facet joint angle of HNP group was higher than normal group in the same level. There was no statistically significant correlation between the facet tropism and lumbar disc herniation. CONCLUSION: These results do not indicate any relationship between the facet tropism and lumbar disc herniation.
