Abstract
- In cases of unstable thoracolumbar burst fractures, recently the operative 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.
The results were as followed:
1. There was no relationship between canal compromise and Frankel grade. Incomplete neurologlc 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, correction angle 13.4, and sorrection 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.
