The present invention relates to a method of inserting an implant comprising providing an expandable vertebral implant. The method further may comprise providing an angling inserter tool. The angling inserter tool comprises a handle portion, a base portion, and a tip assembly, the base portion being disposed between the handle portion and the tip assembly. The method further may comprise distally advancing a central shaft of the tip assembly with rotation into an opening in the expandable vertebral implant to secure the angling inserter tool to the expandable vertebral implant. The method further may comprise positioning the expandable vertebral implant in a patient's spine. The method further may comprise for causing the tip assembly to angulate with respect to a longitudinal axis of the angling inserter tool, wherein the internal shaft is coaxial with an outer cylinder of the base portion.

The invention relates to an ankle prosthesis (1) comprising a talar implant (2) designed to be implanted in or on the talus (3), a tibial implant (4) designed to be implanted in or on the tibia (5), and an intermediate implant (6) designed to be interposed between the tibial implant and the talar implant, said intermediate implant (6) being designed to be mounted to move relative to said talar implant (2) at a contact interface (7) in order to allow the ankle to move, said ankle prosthesis (1) being characterised in that it is provided with configurable coupling means (10) designed to enable the intermediate implant (6) to be arranged relative to the tibial implant (4) in a specific configuration chosen from among a plurality of possible configurations.

An artificial hip joint stem is used to replace the damaged femoral head or acetabulum and includes a stem body having a head fixing part, which fixes a head, and an operating space horizontally opened at the upper side thereof. A head insertion hole connects to the operating space. A screw part is inserted into the head insertion hole. An operation converting part is inserted into the operating space to vertically move by the screw part when the operation converting part is connected to the screw part. A fixing bracket is inserted into the operating space such that the screw part is fixed to rotate without changing the depth thereof. A variable operating part is inserted into a supporting surface of the stem body to adjust a horizontal width by means of the operation converting part. A movable pin fixes the variable operating part to the operation converting part.

Spinal cage devices, systems, and methods of assembly and implanting the devices and systems are disclosed. The cage system includes a cage and at least one locking screw assembly configured to couple to the cage. The spinal cage system includes a cage with a body portion, an external plate, and a rod. The body portion includes at least one opening positioned between the first and second ends, a center opening in the first end, and at least one hole adjacent the center opening. The external plate includes an opening and at least two holes on opposite sides of the opening. The rod extends through the center opening in the cage, the first end configured to couple to the external plate, and the second end positioned in the at least one opening. Methods for assembling a spinal cage system and for implanting a cage system are also disclosed.

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).

An adjustable spinal fusion intervertebral implant including upper and lower body portions each having proximal and distal surfaces at proximal and distal ends thereof. The implant can include a proximal wedge member disposed at the proximal ends of the respective ones of the upper and lower body portions, and a distal wedge member disposed at the distal ends of the respective ones of the upper and lower body portions. First and second linkages can connect the upper and lower body portions. Rotation of an actuator shaft can cause the distal and proximal wedge members to be drawn together such that longitudinal movement of the distal wedge member against the distal surfaces and the longitudinal movement of the proximal wedge member against the proximal surfaces causes separation of the upper and lower body portions.

An implant stabilizes two adjacent bones of a joint, while enabling a natural kinematic relative movement of the bones. Support components are connected to each bone of the joint, and a flexible core is interposed between them. The core and at least one of the support components are provided with a smooth sliding surface upon which the core and support component may slide relative to each other, enabling a corresponding movement of the bones. The surfaces may have a mating curvature, to mimic a natural movement of the joint. The core is resilient, and may bend or compress, enabling the bones to move towards each other, and or to bend relative to each other.

An acetabular hip implant includes a plurality of rings secured to an acetabular shell component. A method of fabricating a customized, patient-specific version of such an implant is also disclosed.
