In cases of unstable thoracolumbar burst fractures, recently the opertive treatments such as posterior stabilization and fusion, anterior decompression and fusion, and combined method have been used and choice of procedures is determined by
neurologic
deficit, instability, and interval between injury and operation.
Kaneda instrumentation is rigid anterior spinal device that provides sufficient stability for anterior decompression through partial or total corpectomy and adequate correction of kyphosis as one stage operation by instrumentation.
We have experienced 12 cases of Kaneda instrumentation via anterior approach for thoracolumbar fracture, from Aug. 1989 to Jun. 1991. Among them, 7 cases have been followed for more than 12 months and reviewed.
@ES The results were as followed:
@EN 1.There was no relationship between canal compromise and Frankel grade. Incomplete neurologic deficit improved by 1.4 Frankel grade but complete neurologic deficit did not improve.
2. The mean preoperative kyphotic angulation was 26.1°, postoperative angulation 12.7。, mean correction angle 13.4。, and correction rate was 51.4%
3. Anterior spinal approach for the unstable thoracolumbar fractures using Kaneda instrumentation provided 1) sufficient anterior spinal decompression and fusion 2) adequate correction of kyphotic deformity and 3) stability to enable
early
ambulation.
