Abstract:
Objective To evaluate the stability and compressive mechanical functions of the lumbar spine following insertion of a new self-made allograft interbody fusion cage.Methods Anti-bending intensity with three points test,anti-rotation intensity and compressive stiffness were measured at L4-L5 lumbar spine on five adult human fresh cadaveric specimens following insertion of a new self-made allograft interbody fusion cage and compared with that of before and after nucleus pulposus removal.Results The anti-bending intensity of flexion and extension of lumbar spine after inserting a new allograft interbody fusion cage was increased significantly(P
