Abstract
A spinal implant includes a first member defining an implant cavity. A second member is movable relative to the first member and penetrable with tissue. A first crown is engageable with the first member, and a second crown is engageable with the second member. The second crown being movable relative to the first crown to fix the first member relative to the second member in a selected orientation. In some embodiments, systems, spinal constructs and methods are disclosed.
Claims11
A spinal implant comprising:
- a first member defining an implant cavity;
- a second member movable relative to the first member and penetrable with tissue;
- a first crown engageable with the first member;
- and
- a second crown engageable with the second member, the second crown being movable relative to the first crown to fix the first member relative to the second member in a selected orientation;
- wherein the second crown includes an outer threaded surface engageable with an inner threaded surface of the first crown;
- wherein the second crown includes a distal surface engageable with a head of the second member, the distal surface comprising a plurality of deformable ribs circumferentially disposed about an approximate center of the second crown;
- and
- wherein each one of the plurality of deformable ribs is disposed in a spaced apart relation to one another and extend radially outward between an interior perimeter and an exterior perimeter of the second crown.
A spinal implant comprising:
- a receiver defining an implant cavity and one or more grooves;
- a shaft movable relative to the receiver;
- one or more bands configured for disposal within the one or more grooves and engageable with a head of the shaft to connect the receiver and the shaft such that the receiver is movable relative to the shaft;
- a first crown engageable with the receiver;
- and
- a second crown engageable with the shaft and movable relative to the first crown between a non locking orientation such that the receiver and the shaft include multi axial relative movement and a locking orientation such that the receiver is fixed relative to the shaft in a selected orientation;
- wherein the second crown includes an outer threaded surface engageable with an inner threaded surface of the first crown;
- wherein the second crown includes an inner socket and a distal surface engageable with a head of the shaft, the distal surface including a plurality of deformable ribs circumferentially disposed on the inner socket about an approximate center of the second crown;
- wherein each one of the plurality of deformable ribs is disposed in a spaced apart relation to one another and extends radially outward between an interior perimeter and an exterior perimeter of the second crown;
- and
- wherein a proximal end of a flange defines a proximal end of the first crown.
