Interbody spinal fusion device

A pair of flat support plates in a spinal fusion implant device contact and rest against the softer, central cancellous bone portion of respective endplates of adjacent vertebrae. Each support plate has a front template that is orthogonal to the plate and is bent to communicate with the anterior surface of the hard cortical endplate the vertebrae. A wedge-shaped support strut in a central channel between the two plates is configured to vary the distance between the support plates such that the height of the device proximate the anterior end is greater than the height of the device at the posterior end to maintain the natural lordosis of the spine. Channels formed on either side of the support strut are filled with bone graft material and contact the endplates of the vertebrae through large openings in the flat support plates to facilitate fusion.

Device for connecting a screw to a support plate

The invention relates to a device which is used for solidly connecting a part such as a plate to an underlying support using at least one fixing element such as a screw. According to the invention, said fixing element takes the form of a threaded rod a screw which passes through a hole housing a ring belonging to the part, such that it is screwed into the support material. The inventive device is characterized in that the above-mentioned ring is a constriction ring comprising a non-circular outer profile which co-operates with the non-circular inner profile of the hole, which is in the part. In this way, when the ring is rotated in the hole and wedged in place therein, it is constricted, thereby blocking the threaded rod against movement with respect to the plate.

Buttress plate system

Systems, devices and methods are provided for assisting in spinal stabilization. A buttress plate system is provided that can include an intervertebral spacer, a buttress plate, a spinal screw, and an insertion instrument. The buttress plate is configured to extend across at least a part of an intervertebral space to block or prevent an intervertebral spacer from backing out of the intervertebral space when the buttress plate is secured to the spine. The buttress plate includes a curved plate body having an aperture therethrough for receiving a spinal screw. The buttress plate also includes a pair of engagement members in the form of spikes to help stabilize the buttress plate relative to the spine prior to securing the buttress plate to the spine. The buttress plate can be coupled to an insertion instrument that is used to guide the buttress plate to a desired position adjacent the spine. Once in a desired position, a spinal screw can be delivered through the insertion instrument and through the aperture of the buttress plate to secure the buttress plate to the spine. The insertion instrument thus helps to properly position the buttress plate adjacent the spine and to deliver a spinal screw toward the aperture of the buttress plate.

Alignable coupling assembly for connecting two prosthetic limb components

An alignable coupling assembly embodiment for coupling distal and proximal prosthetic components includes a pair of parallel circular plates rotatably disposed in the circular receptacle of a support plate. The circular plates are configured such that they can be unpressed or a pressed. The unpressed condition allows rotation of the paired plates and the pressed condition prevents such rotation by way of a first friction lock. The paired circular plates further have a rectangular slot into which a longitudinal connector is slidably disposed, and which is subject to a second friction lock that prevents sliding when the connector is pulled distally. Rotational movement of the plates and sliding movement of the connector in the slot cooperate to allow its positioning at any point within an anterior-posterior / lateral medial grid centered on the longitudinal axis of the proximal prosthetic component. A distal pull on the longitudinal connector engages both first and second friction locks.
