Clinical Trial Summary

IntraSPINE® is a novel device that, unlike interspinous positioned implants, is unique in being placed more anteriorly in an interlaminar position, closer to the normal center of rotation of the motion segment. Mechanical advantages are thus conferred over more posteriorly positioned devices through the possibility of more physiological 'rocking' type movements in flexion and extension . This enables IntraSPINE® to off-load the facet joints in extension without blocking movement. Having a more anteriorly placed fulcrum also helps control excessive flexion movements by virtue of an improved lever arm in conjunction with an intact posterior tension band.

The underlying hypothesis of this work is that a clinical gain is achieved by adding an IntraSPINE® interlaminar device to discectomy in patients suffering from a lumbar disc herniation. This should result in an improvement in incapacity level and a reduction in pain.
