摘要:
An orthopedic implant includes a first member that defines a longitudinal axis, a first wall and a second wall. The first wall defines at least a portion of a chamber. The second wall defines a first graft containment cavity. The chamber is separate from the first graft containment cavity. A second member defines a first wall disposed for sealed engagement with the first wall of the first member. The first wall of the second member defines at least a portion of the chamber. The second member is configured for movement along the longitudinal axis relative to the first member. Methods of use are disclosed.

A spinal stabilization system includes a first stabilization member and a second stabilization member engaged to one another in end-to-end fashion. A coupling system adjustably secures the stabilization members in axial position relative to one another while allowing the relative axial positioning to be adjusted to accommodate growth or other condition or arrangement.

A spinal stabilization system, apparatus, and method are disclosed which include an interconnection mechanism for engaging stabilization members to one another. In one embodiment, the interconnection mechanism comprises a locking member having first and second threaded segments. An anchor member is provided having an upper segment and a lower segment, wherein the lower segment is structurally configured for engagement with a respective bone segment. A first stabilization member is connected to the upper segment of the anchor member. A locking member is engaged with the anchor member such that the first stabilization member is fixedly secured to the anchor member by a lower portion of the locking member having a first threaded segment. A second stabilization member is connected to an upper portion of the locking member by a cap that is threaded onto a second threaded segment of the locking member.

Connector assemblies are provided to couple an elongate member extending along the spinal column to a bone engaging implant engaged to the spinal column. The connector assembly includes a coupler having an implant coupling portion and an elongate member coupling portion. The positioning and orientation of the coupler relative to the implant and elongate member can be adjusted to facilitate engagement of the connector assembly between the implant and elongate member.
摘要:
A fastener assembly for engaging vertebral elements has a connecting body that includes a receptacle extending between a first opening and a second opening and a fastener with a head movably supported in the receptacle. The fastener includes a vertebral engaging portion extending distally through the second opening. The fastener assembly further includes a post that has an elongated body with a proximal portion extending proximally from the first opening of the connecting body, a distal engagement end in the receptacle, and an adjusting portion extending between the proximal portion and the engagement end. The adjusting portion is movably engaged to the connecting body to position the engagement end relative to the head of the fastener to substantially fix the head in the receptacle and resist movement of the fastener with respect to the post and the connecting body.
