Title: IMPLANT FIXATION
Abstract:
A spinal implant system with a spinal anchor implant (20) having a head portion forming the proximal end. Further, the system comprises a support plate (30) being shaped to be placed against the posterior or lateral side of the vertebra and having an anchor receiving structure, wherein the anchor implant extends through the anchor receiving structure into the bone tissue when the anchor implant is anchored in the bone tissue with the support plate between the head portion and the bone tissue. The system also comprises a thermoplastic material (41) in a solid state, the thermoplastic material being shaped and equipped to be placed relative to the anchored anchor implant and the support plate and to be made flowable by the impact of impinging energy so as to bridge and at least partially fill a gap between the anchor implant and the support plate. After re-solidification of the thermoplastic material, the support plate supports the anchored anchor implant in a force transmitting manner via the thermoplastic material.
