IMPLANT DEVICE USED IN MINIMALLY INVASIVE FACET JOINT HEMI-ARTHROPLASTY

摘要

metal implants inverted 'L' shape of the present invention, once the cervical spine (C1) and lumbar 5 time (L5) or within the confines of a facet joint which is located between the back of the head 1 sacrum (S1) is to graft to the lower phase between the facet joint. The metal implant is provided with inner surface parts having an outer surface portion and the texture and polished. Further, without using the screws into cement or for fixing, taking the sheath to contract between the facet joint uses a mechanical means to secure. By having a rough inner surface portion of the porous surface of the implant, resulting in a permanent fixation via the inside according to the invasive growth of bone. The implant is no worse or chronic pain in the joint surfaces of the facet joint, gently, and using the method according to the semi-arthroplasty to be implanted, does not require major surgery or rehabilitation, is the risk for the patient is significantly reduced.
