[Effect of Coflex interspinous stabilization and vertebral arch pedicle screw implantation on the stability of three-dimensional motions of the lumbar spine].

OBJECTIVE To evaluate the effect of Coflex interspinous stabilization and vertebral arch pedicle screw implant on the stability and motion of the lumbar spine. METHODS The range of motion (ROM) of 6 fresh adult human cadaver lumbar spine specimens (L(1) approximately S(1)) was biomechanically tested in forward flexion/extension stretch, left/right lateral… CONTINUE READING
