    摘要： A modular knee prosthesis system comprises a distal femoral articulation component, a distal augment, a posterior augment and a first connector for securing at least one of the augments to the distal femoral articulation component through a bore in the augment and an opening in the distal femoral articulation component. The distal femoral articulation component has a distal bone-facing surface, a posterior bone-facing surface and an opening. The openings into the bores of the augments are in the medial or lateral side surface of the augment. Both augments can be mounted and removed from the distal femoral articulation component from either the medial or lateral side.

    摘要： Instruments and methods are provided for re-positioning and extracting spinal implants in a space between vertebrae. The instruments can include rotater instruments, hook instruments, and extractor instruments engageable to the implant. The extractor instruments can include a shaft assembly, an actuator assembly at a proximal end of said shaft assembly, and an engaging assembly at a distal end of the shaft assembly. The engaging assembly includes a support member fixedly coupled with and extending distally from the shaft assembly and a clamping member coupled with at least one of the shaft assembly and the support member. The actuator assembly is operably linked to the clamping member with the shaft assembly to move the clamping member toward the support member with the actuator assembly.

    摘要： Systems, devices and methods relating to a spinal implant for placement in a disc space of a spine are described. A spinal implant (1) can include a plurality of wedge members including a leading wedge (22), a trailing wedge (28), and one or more intermediary wedges (26) therebetween. The spinal implant (1) can be configured to have a first linear configuration in which the plurality of wedge members are in a linearly expanded form and a second circular configuration in which the plurality of wedge members are positioned circumferentially relative to a center axis. In its first configuration, the spinal implant (1) can be delivered to a disc space, whereby it can assume its second configuration within the disc space, thereby forming a replacement nucleus. The spinal implant (1) can be kept in its first configuration by a rod member (41) received as through the plurality of wedge members. The wedge members can be slidably removed off of the rod member (41) and can assume the second configuration.

    摘要： A method of removing an intervertebral disc prosthesis from an intervertebral disc space includes the steps of: a) providing a surgical extractor with two legs; b) individually inserting the legs, while the legs are completely detached from each other, into the intervertebral disc space; c) rotating the legs so that they take up a locking position in which a pulling force can be applied by the legs to the intervertebral disc prosthesis; d) connecting the legs to an extraction element; and e) pulling at the extraction element so that the legs apply a pulling force to the intervertebral disc prosthesis.
