Abstract
A spinal construct comprises a fastener attached with sacral and/or pelvic tissue of a body. A connector is selectively movable in a coronal plane relative to the body. The connector has a first end connected with the fastener and a second end having a locking surface engageable with an implant. A lock element is engageable with the connector and defines an implant cavity. Systems and methods are disclosed.
Claims20
A spinal construct comprising:
- a fastener configured to be attached with sacral and/or pelvic tissue of a body, the fastener comprising an inner surface defining a connector cavity;
- a connector configured to be selectively movable in a coronal plane relative to the body, the connector having a first end with an even outer surface that engages the inner surface and a second end having a locking surface engageable with an implant, the second end comprising a passageway that extends through the locking surface and an opposite bottom surface of the second end;
- and
- a lock element including a receiver having spaced apart arms that define a portion of an implant cavity, the receiver comprising a raised portion between the arms and a cylindrical shaft that extends from the raised portion, end surfaces of the arms engaging the bottom surface such that the raised portion is nested within the passageway, the shaft comprising a threaded portion and a non-threaded portion that is positioned within the passageway, an inner surface of the non-threaded portion defining a portion of the implant cavity.

A spinal construct comprising:
- a fastener configured to be attached with sacral and/or pelvic tissue of a body, the fastener comprising an inner surface defining a connector cavity;
- a connector having an extension with an even outer surface that engages the inner surface and a disc having a locking surface engageable with an implant that is configured to be attached with vertebrae, the disc comprising a passageway that extends through the locking surface and an opposite bottom surface of the disc;
- and
- a lock element engageable with the connector and including a receiver having spaced arms that define a portion of an implant cavity, the receiver comprising a raised portion between the arms and a cylindrical shaft that extends from the raised portion, end surfaces of the arms engaging the bottom surface such that the raised portion is nested within the passageway, the shaft comprising a threaded portion and a non-threaded portion that is positioned within the passageway, an inner surface of the non-threaded portion defining a portion of the implant cavity,
- wherein the connector is selectively rotatable relative to the implant in a coronal plane for alignment with the fastener.

A spinal construct comprising:
- a fastener comprising a threaded shank and a head having an inner surface defining a connector cavity;
- a connector having an extension with an even outer surface that engages the inner surface and a disc having opposite top and bottom surfaces and a passageway that extends through the top and bottom surfaces, the top and bottom surfaces each comprising a planar portion and a locking portion, the locking portions each comprising splines disposed in an increasing radial orientation about the passageway, the planar portion of the bottom surface being recessed from the locking portion of the bottom surface to define a cavity;
- a lock element including a receiver having spaced arms that define a portion an implant cavity, the receiver comprising a raised portion between the arms and a cylindrical shaft that extends from the raised portion, end surfaces of the arms engaging the bottom surface such that the raised portion is nested within the cavity, the shaft comprising a threaded portion and a non-threaded portion that is positioned within the passageway, an inner surface of the non-threaded portion defining a portion of the implant cavity;
- and
- a nut comprising a body having an end surface that engages the top surface, the body comprising a threaded cavity that extends through the end surface, the threaded portion being disposed in the threaded cavity, the nut comprising a flange that extends from the body, the flange being configured to break off from the body.
