The present disclosure provides a hipbone prosthesis, comprising: a prosthesis main body (10), the prosthesis main body (10) being of an arched structure, the prosthesis main body including a first end portion (11) and a second end portion, and the first end portion (11) being contacted and matched with a sacrum (1); and an acetabular cup (20) and a connecting device (30), the acetabular cup (20) being connected with the second end portion in a position adjustable manner via the connecting device (30). According to the technical solutions of the present disclosure, the problems of unreliable supporting and easy fatigue break of a screw-rod system in the related technology are effectively solved.

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.

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.

The present invention relates to an expandable implant for engagement between vertebrae generally comprising an inner member, outer member, and gear member positioned coaxial with respect to each other such that the inner and outer members are moveable relative to each other along an axis. The gear member is axially fixed to the outer member and freely rotatable with respect to the outer member and the gear member threadedly engages a threaded portion of the inner member to translate inner member along the axis. The implant is configured to engage the vertebrae in a predetermined alignment and the gear member includes gear teeth exposed to the exterior and configured to be accessible by a tool member at a plurality of angular positions around the perimeter of the implant device.

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.

Provided is an elbow joint prosthetic implant (100) comprising: a humeral component (50) comprising a humeral stem portion (60) configured for placement within the humeral intramedullary canal of a subject, an ulnar component (110) comprising an ulnar stem portion (120) configured for placement within the ulnar intramedullary canal of the subject, wherein the humeral component (50) and ulnar component (110) are connected by an implant elbow joint (130), wherein the ulnar component (110) further comprises an angulation joint (140) that is separate from the implant elbow joint (130), wherein the angulation joint (140) and has at least one degree of freedom of rotational movement configured to adjust and fix a varus-valgus direction of the ulnar stem portion (120).

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.
