A glenoid implant that is 3D-printed or machined from ceramic and/or metal as a substitute for an autograft or allograft in a surgical repair. Structural supports composed of metal are designed in the interior of the implant for support during implantation and post-operation. The remainder of the volume of the implant is composed of a material having optimal pore structure for rapid bone integration and healing.

The utility model provides an artificial bone, comprising bionic bone, supporting pillar and 3D porous scaffold structure; said supporting pillar and said 3D porous scaffold structure are connected to said bionic bone, said 3D porous scaffold structure is set to cover said supporting pillar. Advantageous result of the utility model is: use artificial bone to replace original bone, set supporting pillar and 3D porous scaffold structure in the meantime, supporting pillar gets into coupling end which connected to original bone to work as support and fixing. Set the 3D porous scaffold structure on the periphery of coupling end which connected to original bone, to provide space for the adhesion and growth of bone cells, make the connection between artificial bone and original bone more stable.

An apparatus including a joint spacer for treatment of a joint of a human subject. The joint spacer includes a bioresorbable stent having compressed and expanded configurations and a covering that covers an external surface of the stent. The joint spacer is configured to be inserted into a space of the joint, and is shaped, when the bioresorbable stent is in the expanded configuration, to provide mechanical support to the joint until the bioresorbable stent resorbs into a body of the subject. Treating a joint of a human subject includes inserting a joint spacer into a space of the joint while a bioresorbable stent of the joint spacer is in a compressed configuration, and transitioning the bioresorbable stent to an expanded configuration within the joint, such that the joint spacer provides mechanical support to the joint until the bioresorbable stent resorbs into a body of the subject.

A hip prosthesis head includes: an external element with a convex external surface, and an internal element having a truncated-conical seat; wherein the external element and the internal element are made of different materials; the internal element is coupled in a blind hole of the external element in fit-in coupling mode; the external element has an annular base around the blind hole, and the internal element has a truncated-conical body that is open on the bottom, and an annular base that protrudes radially outwards from a lower edge of the body in order to be in contact with the base of the external element.

The invention discloses a bionic artificial hip joint. The artificial hip joint includes a femoral stem located above corpus femoris, and a convex force-bearing part is provided on the femoral stem. The force-bearing part abuts against the inner side of the cortex on greater trochanter and bears a part of the longitudinal stress; its hollow design is convenient for bone grafting, so that the prosthesis and the greater trochanter can be integrated. Replacement surgery can preserve the hard cortex on the greater trochanter, providing another focus point for the femoral stem and further improving the stability of the connection between the bionic artificial hip joint and corpus femoris.

An arthroplasty system may include a first prosthesis to be fixed to a first bone of a joint, a second prosthesis to be fixed to a second bone of the joint for articulation with the first prosthesis, and one or more adapters to be fixed to the first prosthesis for articulation with the second prosthesis to modify the stability of the second prosthesis relative to the first prosthesis. The system may include one or more articular inserts to be coupled to the second prosthesis for articulation with the first prosthesis and/or the adapter(s). The articular inserts may be fixed or mobile bearing relative to the second prosthesis. Each adapter and corresponding articular insert may modify stability differently.

Embodiments of an implant for use in surgery are disclosed. The implant may include elastic polymer file made from a suitable biologically compatible polymer. The implant may also include a reinforcement element.

A method and system for performing bone fusion and/or securing one or more bones, such as adjacent vertebra, are disclosed. The screws include a threaded tip connected to a main shaft and a threaded outer sleeve that rotates relative to the outer shaft until locked down. Independent rotation of the threaded outer sleeve relative to the threaded distal tip allows compression or distraction to modify the gap between the vertebral bodies. The screws are passed from the inferior to superior vertebra or superior to inferior, for example, through a trans-pedicular route to avoid neurological compromise. At the same time, the path of screw insertion is oriented to reach superior or inferior vertebra. An intervertebral cage of the system is configured for lateral expansion from a nearly straight configuration to form a large footprint in the disc space. The screws and cage may be combined for improved fixation with minimal invasiveness.

A hip implant having two distinct bodies, a neck body and a bone fixation body. The neck body is formed from a solid metal and has an interface for connecting to a femoral ball. The bone fixation body has an elongated shape and is formed as a porous structure that is inserted into an intramedullary canal of a patient.

A bone graft delivery kit includes a hollow tube having a proximal end and a distal end. The hollow tube is configured to convey graft material to a graft receiving area in a patient. The hollow tube can be connected to an implant. The kit further includes a plunger to facilitate moving the graft material through the hollow tube.
