摘要

#CMT# #/CMT# The surgical equipment has bone anchor (2) which is anchored in a treated vertebrae (100). Two rigid walls (3) connected to the bone anchor, are arranged on each side of spinous process (101) of treated vertebrae and sized to extend over the height of spinous process, to limit pivot movements of vertebrae about an axis perpendicular to the intervertebral disk. #CMT#USE : #/CMT# For use in treatment of lumbar vertebrae affected by facet arthropathies, rotational spondylolisthesis, arthrodesis, post-disk arthroplasty lumbago. #CMT#ADVANTAGE : #/CMT# Limits pivot movements of vertebrae about an axis perpendicular to the intervertebral disk. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a schematic view of the surgical equipment. 1 : Surgical equipment 2 : Bone anchor 3 : Rigid wall 100 : Vertebrae 101 : Spinous process.
