The invention relates to a modular interim joint prosthesis that can be inserted into a long bone, for replacing an explanted joint endoprosthesis, wherein the interim joint prosthesis has a main body having a main-body coupling segment and has a shaft having a shaft coupling segment and the shaft coupling segment can be detachably coupled to the main-body coupling segment.

A method for separating an implant from a bone, includes interfacing a tool with an implant including a flange, the flange including a proximal surface and a distal surface, the distal surface bearing on or facing the bone, the flange including an aperture defined through the flange; inserting an elongate element through the aperture from the proximal surface to the distal surface and into the bone; and partially separating a bonding interface between the implant and the bone using the elongate element.

An intervertebral implant has a hollow space formed within the implant and accessible through an elongate opening extending through a recessed portion of the side wall, and the hollow space is shaped to receive an engagement portion of a drive shaft of an insertion tool; and the intervertebral implant includes at least two guiding surfaces facing each other and being configured for sliding engagement by a portion of a sleeve of the insertion tool movably holding the drive shaft.

A surgical tool, enabling extraction of a prosthesis from a bony implantation site of that prosthesis, defines a proximo-distal axis and includes a distal end head adapted both to cut at least partially the bonding interface between the prosthesis and the bony material of the implantation site and to fix itself to the prosthesis by rotation centered on the proximo-distal axis, according to embodiments of the present invention.

An intervertebral implant has a hollow space formed within the implant and accessible through an elongate opening extending through a recessed portion of the side wall, and the hollow space is shaped to receive an engagement portion of a drive shaft of an insertion tool; and the intervertebral implant includes at least two guiding surfaces facing each other and being configured for sliding engagement by a portion of a sleeve of the insertion tool movably holding the drive shaft.

An intervertebral implant includes a body having a first face, a second face connected to and opposite the first face, a width and a length at least as long as the width that extend around the first and second faces, and first and second connection portions for connecting the implant to a separate holding member. The first and second connection portions each includes a hollow space accessible from outside the body through an opening formed between the first and second faces. The openings are elongate and extend away from one another around the implant from a same first side that defines the length of the body to respective second and third sides opposite to one another that define the width of the body, and are arranged such that the first and second connection portions are simultaneously engageable by the holding member.

An intervertebral spacer assembly may include a first intervertebral spacer with a superior surface configured to engage a superior vertebral body, an inferior surface configured to engage an inferior vertebral body, and a proximal surface with a first fastener channel. The assembly may further include a first fastener and a locking member with a first anti-backout member. The first intervertebral spacer or the locking member may have a locking member channel. The other may have a compressible collet insertable into the locking member channel to couple the locking member to the first intervertebral spacer such that the locking member is rotatable relative to the first intervertebral spacer between an unlocked position in which the first anti-backout member does not obstruct the first fastener channel, and a locked position in which the first anti-backout member obstructs the first fastener channel to retain the first fastener in the first fastener channel.

An intervertebral cage implant may include a first deployable keel, and a second deployable keel. A first portion of the first keel is configured to deploy from the cage in a generally superior direction and a second portion of the second keel is configured to deploy from the cage in a generally inferior direction to. The first keel is configured to deploy at a first angle less than 90° relative to a superior surface of the cage and the second keel is configured to deploy at a second angle less than 90° relative to an inferior surface of the cage. The first angle is substantially the same as the second angle, such that the first edge of the first blade is substantially parallel to the first edge of the second blade.

A spinal implant system is provided for bridging an intervertebral space between vertebral bodies bordering the intervertebral space. The spinal implant system includes at least one adjustable end cap and a spinal implant. The end cap can be used with additional end caps and/or the spinal implant. Multiple end caps can be stacked on top of one another, and one end cap can be attached to a first end of the spinal implant, and another end cap can be attached to a second end of the spinal implant. Thus, one or more of the end caps can be attached to either end of the spinal implant.

A prosthetic component (2) adapted to be mounted to a bone as part of a knee prosthesis comprises a spacing element for compensating resected bone. The prosthetic component (2) further comprises a main body (6) with a contact surface (7) configured to abut the spacing element and a fixation mechanism (9) for fixing the spacing element between the contact surface (7) and the bone.

The fixation mechanism (9) comprises a receiving portion (10) located at the contact surface (7). The fixation mechanism (9) further comprises an insert (11) for insertion into the receiving portion (10) and a fastening element adapted to engage with the insert (11). The receiving portion (10) is adapted to fix the insert (11) via a bayonet joint connection such that the fastening element, extending through the spacing element and engaging with the insert (11), fixes the spacing element to the contact surface (7).
