Abstract: An intervertebral cage includes first and second support surfaces arranged for pivoting about a pivot, and one or more lifting cams and an actuating shaft for actuating the cams. Actuation of the cams causes non-parallel movement of one of the first and second support surfaces with respect to the other support surface.

Abstract: An assembly including a connector element including a receptacle from which extends a neck, a lug element sized to fit in the receptacle of the connector element, ears pivotally connected to the lug element, and a mechanical fastener that fastens the connector element together with the lug element, thereby causing the ears to pivot and grip a connector rod placed between the ears.

Abstract: An expandable bone device including first and second bone support elements, a manipulator positioned between the first and second bone support elements and connected to them by link members, the manipulator adapted to move the first and second bone support elements between a collapsed orientation and an expanded orientation, wherein in the collapsed orientation the first and second bone support elements are drawn towards the manipulator and in the expanded orientation the first and second bone support elements are moved outwards away from a longitudinal axis of the manipulator, and deformable support struts connected between the manipulator and the first and second bone support elements that deform when moved by the manipulator from the collapsed orientation to the expanded orientation and vice versa, wherein in the expanded orientation the deformable support struts form a structure that maintains the first and second bone support elements in the expanded orientation.

Abstract: A bone treatment device comprises a shaft having a tubular wall, a lumen extending within the tubular wall, openings through the tubular wall, and anchoring elements adjacent the openings that can be deployed out of the openings in the presence of an actuating force within the shaft lumen. The bone treatment device may further comprise an actuator configured to be received within the shaft lumen to deploy the anchoring elements out of the openings.

Abstract: An intramedullary device used to stabilize a variety of fractured bones includes a plurality of resilient spine elements. A porous interconnection structure interconnects the spine elements, such as a mesh or a plurality of struts connected between the spine elements. The device expands at one or both ends, and optionally, the shaft of the device can also expand.

The spine elements and/or the interconnection structure are pre-shaped, e.g., composed of a resilient material and pre-shaped, such that the end of the device expands in the absence of an external restraining force. The spine elements and/or interconnection structure can be composed of a shape memory material, such that the expandable end of the device expands when heated to a temperature above a transitional temperature of the shape memory material.
