Abstract
A spinal construct includes a first endplate that is configured to engage a first vertebral surface. An expandable member is connected with the first endplate and includes a mating element. A second endplate is configured to engage a second vertebral surface and includes an in-situ guide surface engageable with the mating element to connect the member with the second endplate. Systems and methods are disclosed.
Claims20
A spinal construct comprising:
- an expandable member including an outer body and an inner body movably positioned within an axial cavity of the outer body, the inner body comprising spaced apart indentations that each extend perpendicular to a longitudinal axis defined by the axial cavity, the indentations being configured for engagement with a surgical instrument to facilitate axial translation of the inner body relative to the outer body;
- a plating element coupled to the expandable member;
- an endplate engageable with the mating element to connect the expandable member with the endplate;
- and
- a spinal rod attachable with vertebral surfaces and a support connected with the expandable member and the spinal rod.

A spinal construct comprising:
- an expandable member including an outer body and an inner body movably positioned within an axial cavity of the outer body, the inner body comprising spaced apart indentations that each extend perpendicular to a longitudinal axis defined by the axial cavity, the indentations extending into an outer surface of the inner body without extending through an opposite inner surface of the inner body, the indentations extending about only a portion of a circumference of the inner body, the indentations being configured for engagement with a surgical instrument to facilitate axial translation of the inner body relative to the outer body;
- a first mating element coupled to the inner body;
- a second mating element coupled to the outer body;
- a first endplate comprising a socket, a head of the first mating element being positioned within the socket such that the head and the socket define a ball and socket joint;
- a second endplates comprising a socket, a head of the second mating element being positioned within the socket of the second endplate such that the head of the second mating element and the socket of the second endplate define a ball and socket joint;
- and
- a spinal rod attachable with vertebral surfaces and a support connected with the expandable member and the spinal rod.
