Abstract
Articulating implant connectors and related methods are disclosed herein. Exemplary connectors can include first and second bodies that are rotatable relative to one another about a rotation axis and selectively lockable to resist or prevent such rotation. Each of the bodies can be configured to couple to a rod or other fixation component, and the connector can be used to lock first and second rods together even when the rods are obliquely angled with respect to one another.
Claims27
A connector, comprising:
- a first body that defines a first rod-receiving recess, the first body having proximal and distal ends that define a proximal-distal axis extending therebetween;
- a second body that defines a second rod-receiving recess, the second body having proximal and distal ends that define a proximal-distal axis extending therebetween;
- a hinge pin that couples the first body to the second body, a central longitudinal axis of the hinge pin defining a rotation axis about which the first and second bodies rotate relative to one another;
- and
- a fastener movable with respect to at least one of the first and second bodies to urge the first and second bodies towards one another along the rotation axis and thereby lock relative rotation of the first and second bodies about the rotation axis.
2 more elements
A connector, comprising:
- a first body that defines a first rod-receiving recess;
- a hinge pin formed integrally with the first body and extending laterally therefrom to a free end;
- a second body that defines a second rod-receiving recess, the second body having a cavity in which the free end of the hinge pin is received to couple the second body to the first body such that the first and second bodies rotate relative to one another about a rotation axis;
- a first fastener configured to secure a first rod within the first rod-receiving recess;
- and
- a second fastener configured to secure a second rod within the second rod-receiving recess and to urge the first and second bodies towards one another along the rotation axis to lock relative rotation of the first and second bodies about the rotation axis.
3 more elements
A surgical method, comprising:
- inserting a first rod into a first rod-receiving recess of a first body of a connector;
- inserting a second rod into a second rod-receiving recess of a second body of the connector, the second body being coupled to the first body by a hinge pin;
- rotating the first body relative to the second body about a rotation axis defined by the hinge pin;
- moving a fastener with respect to at least one of the first and second bodies to urge the first and second bodies towards one another along the rotation axis and thereby lock relative rotation of the first and second bodies about the rotation axis;
- and
- securing the first and second rods to an anatomy of a patient.
