ANALYSIS OF THE EFFECT OF 3 KINDS INSTRUMENTATION IN TREATMENT OF SCOLIOSIS

Objective To analyse the result of three instrument (Harrington,Luque and C-D) during correction of scoliosis. To evaluate the cause of the complications and dicuss how to prevent and manage them. Methods Sixty-eight cases of scoliosis were corrected at an average of 15.5 years from February 1992 to October1998.The average preoperative Cobb angle was 62°(range 45°～120°).20 patients were treated with the Harrington instrumeatation, 32 patients were treated with the Luque instrumentation, 16 patients were treated with the C-D system. Results The average rate of correction was 62%,meanwhile complications were found in 16 cases.There were intraoperative laminar or pedicle fractures in 4, neurological injury in 1, pneumonia in 1,loosening in 3,rod breakage in 2,pseudojoint in 1,bulge of C-D rods in 3,and infection in 1. Conclusion The 3 kinds instrumentation should be used base on the degree of the scoliosis, it is very important to balance the ratio of the correction and the safety to decrease the complications.
