Patent number: 7137983Abstract: A set of surgical instruments for the fusion of vertebrae contains supporting elements that have a threaded stem that can be screwed into the vertebra and a head part positioned at the outer end of the threaded stem. A connection unit is fitted between the supporting elements and a fixating device serving to brace together the supporting elements and the connection unit, and the head part of the supporting element has an accepting opening suitable for joining the connecting unit. The accepting opening is formed by the unification of an introductory cleft running from the outer surface of the head part and penetrating into the head part, and a lead-through seat that forms the continuation of the introductory cleft, is worked into the head part and bells out from there. The head part has a fusion opening that has a first connection piece and ends in the lead-through seat, and the fixating device has a tightening body that is positioned in the fusion opening so that it may move.Type: GrantFiled: November 16, 2001Date of Patent: November 21, 2006Assignee: Sanatmetal KFTInventors: József Farkas, Péter Pál Varga

Patent number: 6852127Abstract: An intervertebral spacer adapted for implanting between adjacent vertebral bodies of a human spine as a load-bearing replacement for a spinal disc. The spacing member includes an external, non-porous, concavo-convex contour with respect to one dimension of the spacing member. The spacing member is preferably constructed from a rigid, non-resilient load-bearing material that is incapable of elastic deformation. The spacing member is inserted with the aid of a sheathed trocar device that is releasably attached to the spacer, to enable implantation and selective positioning of the spacer by the surgeon from the posterior side of the spine, without the need to retract the dural nerve or the posterior longitudinal ligament.Type: GrantFiled: January 22, 2002Date of Patent: February 8, 2005Assignee: Ortho Development CorporationInventors: Peter Pal Varga, James A. Ogilvie
