摘要:
A minimally invasive intervertebral implant includes a circuitous body defining a luminal axis extending longitudinally therethrough. The circuitous body includes proximal and distal ends oppositely disposed along a lateral axis of the circuitous body. Each of the proximal and distal ends includes an aperture disposed therethrough such that the circuitous body includes a first configuration wherein the proximal and distal ends are at a maximum separation and a second configuration wherein the proximal and distal ends are closer together than in the first configuration.

This application relates to a prosthesis 12 and a cover 1 for a residual limb, wherein: the cover 1 comprises a first region 8 that is normally of a greater circumference than an adjacent second region of the cover, said first region being resiliently deformable so as to temporarily reduce the circumference of that region of the cover, and the prosthesis 12 comprises a portion that defines an internal cavity 11 into which a residual limb that is at least partly covered by said cover 1 may be inserted, wherein said cavity 11 is configured to include a first region 13 that has a first cross-sectional area and below said first region in the direction of limb insertion, a second region 15 that has a second cross-sectional area larger than said first, the arrangement being such that said resiliently deformable first region 8 of said cover deforms to reduce the circumference of that region of said cover as the cover 1 moves through said first region 13 of the cavity, and expands in said second region 15 of the cavity to thereby couple the prosthesis 12 to the user's covered residual limb. A cover with a nipple and a prosthesis with a complementary socket are also disclosed.

Instrumentation for implanting an artificial intervertebral disc includes static trials, the static trials including first and second trial baseplates immovably coupled to one another via a trunk extending therebetween, each trial baseplate having an outwardly facing surface approximating a contour of a corresponding outwardly facing surface of an articifial intervertebral disc baseplate, at least one of the trial baseplates having a plurality of engagement holes extending into the at least one of the trial baseplates in a direction substantially perpendicular to each of a plurality of a surgical approach directions used to insert the trial into the intervertebral space, each of the plurality of engagement holes being disposed on the at least one of the trial baseplates to correspond to a respective one of the surgical approach directions such that selection for use of one of the plurality of engagement holes corresponds to selection of the respective surgical approach.
摘要:
An intervertebral spacer having opposing plates seatable against opposing vertebral bones, separated by at least one convex element, preferably a radially slotted convex element having a wide end rigidly fixed to an upper plate and a narrow end rotatably mounted to a lower plate. The lower plate includes a central post extending upwardly from the inner surface of the lower plate, the post including a head that is received in a central opening in the narrow end of the convex element so that the convex element is allowed to rotate with respect to the lower plate so that the plates can rotate relative to one another.
