For degenerative lumbar instability, various spinal instrumentations have been used to
relieve clinical symptom and to stabilize the spine. Most of them are rigid fixation
which cause a postfusion instability at adjacent segment with high incidence. It creates
a highly susceptible region(neo-hinge) between fixed rigid segment and nonfixed mobile
segment. Eventually acceleration of degenerative change in adjacent segment is resulted
with clinical deterioration. To avoid of postfusion instability after rigid fixation, a
semi-rigid fixation system which has a intermediate transitional zone is developed.
In 98 patients with degenerative lumbar instability, semi- rigid fixation which had a
damper in the middle of plate were performed with CH titanium cage. Angular
instability in lateral dynamic X-ray was improved in all case immediately after
operation. Translational instability also much improved. But no degenerative changes or
instability in adjacent segment(neo-hinge disc) or overlying disc within fusion segment
during follow up period of average 16 months. Excellent and good clinical results were
achieved in 90.8% of patients and the solid bone fusion was occurred in 98.9%
