Abstract
A spinal construct comprises a fastener including a head. A member includes an inner surface defining a cavity configured for disposal of the head and a groove configured for disposal of a band that is engageable with the head to connect the fastener and the member. The member includes a transverse rod. A coupling member is engageable with the inner surface. Implants, systems, instruments and methods are disclosed.
Claims20
A spinal construct comprising:
- a fastener comprising a head and a shaft connected to the head, the fastener including a monolithic base, the head being disposed in the base such that the base extends 360 degrees about the head, the base including a groove;
- a member including a body having opposite top and bottom walls and a side wall extending from the top wall to the bottom wall, the member defining a circular bore extending through the top wall, an opening extending through the bottom wall, a cavity configured for disposal of the head, and a groove configured for disposal of a band, the member further including a transverse rod extending outwardly from the side wall;
- a crown disposed in the cavity;
- and
- a part disposable with the cavity and comprising a groove,
- wherein the base is configured to move relative to the member to move the spinal construct from a first orientation in which the band is disposed in the groove of the part and the groove of the member to a second orientation in which the band is disposed in the groove of the base and the groove of the member to connect the member and the fastener, the crown being stationary relative to the member as the spinal construct moves from the first orientation to the second orientation;
- wherein the part directly engages the crown when the spinal construct is in the first orientation and the second orientation.

A spinal construct comprising:
- a bone screw comprising a head and a shaft connected to the head, the bone screw including a monolithic base, the head being disposed in the base such that the base extends 360 degrees about the head, the base including a groove;
- a receiver comprising a body having opposite top and bottom walls and a side wall extending from the top wall to the bottom wall, the receiver defining a circular bore extending through the top wall, the body including an inner surface defining an opening extending through the bottom wall, a cavity for disposal of the head and a groove;
- an expandable ring being disposable with the groove of the receiver;
- a transverse rod extending from the side wall such that the rod is permanently fixed to the body;
- a crown disposable in the cavity;
- and
- a sleeve positioned within the cavity and including a groove,
- wherein the base is configured to move relative to the receiver to move the spinal construct from a first orientation in which the ring is disposed in the groove of the sleeve and the groove of the receiver to a second orientation in which the ring is disposed in the groove of the base and the groove of the receiver to connect the receiver and the bone screw, the crown being stationary relative to the receiver as the spinal construct moves from the first orientation to the second orientation;
- wherein the sleeve directly engages the crown when the spinal construct is in the first orientation and the second orientation.

A spinal construct comprising:
- a fastener comprising a head and a shaft connected to the head, the fastener including a monolithic base, the head being disposed in the base such that the base extends 360 degrees about the head, the base including a groove;
- a receiver comprising a body having opposite top and bottom walls and a side wall extending from the top wall to the bottom wall, the receiver defining a threaded circular bore extending through the top wall, the body defining a beveled opening extending through the bottom wall, a cavity configured for disposal of the head and a groove configured for disposal of a band, the receiver further including a transverse rod extending from the side wall, the rod being monolithically formed with the body;
- and
- a part disposed with the cavity and comprising a groove
- the base being configured to move relative to the receiver to move the spinal construct from a first orientation in which the band is disposed in the groove of the part and the groove of the receiver to a second orientation in which the band is disposed in the groove of the base and the groove of the receiver to connect the receiver and the fastener, the crown being stationary relative to the receiver as the spinal construct moves from the first orientation to the second orientation;
- wherein the part directly engages the crown when the spinal construct is in the first orientation and the second orientation.
