Anterior lnterbody Fusion using KANEDA Instrument in Tuberculous Spondylitis: Case Report

We reported 2 cases of tuberculous spondylitis and its treatment was improved with anterior interbody fusion by a KANEDA instrument. The patients were early ambulation without any complications and sequalaes.

Experience of Management of Unstable Thoraco-Lumbar Spine Using V.S.P(Variable Screw Placement) Plate

Fourteen consecutive patients underwent application of V.S.P(Variable Screw Placement) spinal plate between January 1989 and July 1989. Operative indications were spondylolisthesis, spinal stenosis, segmental instability, herniated disc with instability, pseudoarthrosis. unstable fracture, and failed surgery syndrome. Our patients consist of 8 cases of spondylolisthesis, 4 cases of fracture-dislocation, one case of spondylolysis with instability, one case of herniated disc(L1- 2 interspace). Overall results showed 36% excellent, 50% good, 7% fair, 7% poor. Two deep wound infections were observed. Screw alignment and the angular relationship of each screw to the spinal plate is considered as important technical factors in minimizing screw failure.
