Degenerative involution of the causes destruction of spinal stabilizer which consist of
bone, ligament, joint capsule. and disc which substantially leads to hypermobility and
instability of the spine.
Generally the hard fixation system has used for the treatment of lumber instability.
However, it has many complications. including screw loosening. screw fracture, and
instability on. above, and below the fusion segment. These complications of the hard
fixation system has brought to the invention of a more physiologic fixation device. the
soft fixation system.
We have used the Graf soft fixation system as an instrument for degenerative lumbar
disease 106 cases were operated between August. 1993 and March, 1996. The clinical
assessments. radiologic findings, and operative results were analyzed.
The height of disc space significantly increased from 8.84§® to 9.84§® on L3/4 9.28§®
to 10.13§® on L4/5, -2.09¡Æto 10.81¡Æ on L5/Sl, translation instability was corrected from
16.8% to 14.9% on L3/4 19.9% to 12.4% on L4/5 27.1% to 20.l% on L5/S1 after Graf
soft fixation.
The clinical results were as follows : excellent in 56%, 27% good. 9% fair and 8%
poor.
These results suggest that Graf soft fixation system for degenerative lumbar disease
would not only be useful and effective, but also be safer in terms of unwanted
complications of the hard fixation system.
