RESUMO
OBJECTIVE: To investigate the effectiveness of different instrumentation on idiopathic scoliosis. METHODS: The information before and after the operations of 94 cases of idiopathic scoliosis, which included Harrington, Harrington-Luque (H-L), Cotrel-Dubousset (C-D), and TSRH 3-dimension correction, were collected and analyzed on a long-term basis, and different operative methods were compared for their advantages and disadvantages. RESULTS: Based on 1 to 3 years inquiries following 94 cases, the respective average correcting rates of the above mentioned instrumentations were 36.42%, 45.18%, 55.68%, 63.28%, which proved that H-L, C-D and TSRH were superior to Harrington in the correction rate and that TSRH 3-dimension correction was even more remarkable. CONCLUSION: The effectiveness of 3-dimension correction was superior to those of other instrumentation.
