摘要:
An interbody fusion device for fusion of vertebrae, and methods thereof. The device includes a first piece made of titanium having upper and lower surfaces configured to engage the endplates of two opposing vertebrae. The upper and lower surfaces include a plurality of barbed teeth configured to engage an endplate. The first piece includes an inner void area configured to receive a second piece. The second piece is configured to engage the first piece to slide over inner surfaces of the first piece become seated and mated in the first piece. The first and second pieces mate to form an assembled interbody fusion device that fits between two vertebrae.
摘要:
A method and apparatus is provided for use in spinal fusion procedures. An interbody fusion device has a first piece that is a load bearing device designed to bear the axial loading from the end plates of adjacent vertebrae. A second piece of the interbody fusion device is a retention device whose function is to prevent migration of the load bearing device. One or more fasteners secure the retention device to the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion. The second piece can be configured to include lips that abut the apothyseal rings during, with the plate including bores angled such that fasteners penetrate the apothyseal rings.
摘要:
A distraction pin for aspiration of a bone fluid and marrow. The pin includes an elongate metallic shaft of generally uniform diameter having a proximate end. The proximate end of the shaft includes an adaptor (attachment means) and a longitudinal bore extending from the distal end to the proximate end. The distal end of the shaft includes threading adapted for screwing the shaft into bone. The distal end also includes at least two fenestrations transverse to the longitudinal bore.
