摘要:
A kit for implanting a glenoid component includes a retroversion glenoid component having a generally flat glenoid bone contacting surface defining a first plane. The component has a first offset peg extending away from the glenoid bone contacting surface, a concave articulating surface, an upper surface extending about the concave articulating surface and generally opposite to the glenoid bone contacting surface. The upper surface defines a second plane which is angled with respect to the first plane. The glenoid bone contacting surface defines a circular periphery with the centre peg centred within the circular periphery, and the nadir of the concave articulating surface located on the centre peg axis. A drill guide is configured to guide a drill in forming a bore in a scapula to receive the first offset peg.

An intervertebral implant (100) includes an insertion end (110), an opposing engagement end (115), and first and second opposed main surfaces (120,125) configured to contact respective adjacent vertebral endplates. Each of the first and second main surfaces has an anterior edge, a posterior edge, and extends between the insertion and engagement ends. Anterior and posterior walls (130) are formed between the first and second main surfaces and along the respective anterior and posterior edges and converge at the insertion and engagement ends. A slot (135) is formed at the engagement end and extends continuously between and at least partially along the anterior and posterior walls. A post (180) is positioned within the slot, spaced from at least one of the anterior and posterior walls and extending at least partially between the first and second main surfaces. The post includes a plurality of exposed facets and is configured for engagement with a pivotable insertion instrument.
摘要:
An intervertebral implant is provided. The intervertebral implant comprises a first component comprising an outer tissue engaging surface and an inner surface. A second component is connected to the first component, and is relatively moveable thereform. The second component comprises an outer tissue engaging surface and an inner surface. The second component includes an actuator. A third component is disposed for engagement and is movable relative to the first and second components. The third component comprises at least a first ramp and a second ramp axially spaced apart from the first ramp. The actuator is engageable with the third component to effect axial translation of the wedge such that the ramps engage the inner surface of at least one of the first component and the second component to move the components between a first, collapsed configuration and a second, expanded configuration. Methods of use are disclosed.
摘要:
An interbody spinal implant (1) including a body having a top surface (10), a bottom surface (20), opposing lateral sides (30), opposing anterior and posterior portions (40,50), and a substantially hollow center in communication with a vertical aperture (60), which are filled with a bone graft material. The dimensions, shape, and position of the vertical aperture (60) facilitate contact between the bone graft material and vertebral endplate bone to support and enhance bone growth.
