A stemless humeral head replacement system including a base plate and a humeral head implant. The base plate includes a bone facing side, an implant side opposite the bone facing side, a curvate perimeter, at least one fin protruding from the bone facing side a first distance and extending linearly a length along the bone facing side, and an implant engagement structure on the implant side. The humeral head implant includes a curvate implant surface and a base plate engagement structure opposite the curvate implant surface, the base plate engagement structure configured to couple to the implant engagement structure of the base plate.

A ceramic monobloc femoral component (10) is provided for a total hip replacement prosthesis. The ceramic monobloc femoral component (10) has a ceramic femoral stem (14) and a ceramic head (12) which defines a part-spherical articular surface receivable by an acetabular cup (56). The ceramic femoral stem (14) and the ceramic head (12) are integrally formed as one-piece.

A method of implanting a glenoid assembly, includes forming a first bore in a glenoid region of a scapula and inserting a first peg of a glenoid component into the first bore. The method includes plastically deforming a first passageway within the first peg, while the first peg is inserted into the first bore, by inserting a first stiffening pin into the first passageway.

Disclosed is a central augment. The central augment can include a body and a protrusion. The body can include a first curved surface shaped to interface with a central portion of a bone and a second surface opposite the first curved surface and defining a recess sized to receive a portion of a prosthetic component. The protrusion can extend from the second surface within the recess.

Hard-tissue implants are provided that include a bulk implant, a face, pillars, slots, and at least one support member. The pillars are for contacting a hard tissue. The slots are to be occupied by the hard tissue. The at least one support member is for contacting the hard tissue. The hard-tissue implant has a Young's modulus of elasticity of at least 3 GPa, and has a ratio of the sum of (i) the volumes of the slots to (ii) the sum of the volumes of the pillars and the volumes of the slots of 0.40:1 to 0.90:1. Methods of making and using hard-tissue implants are also provided.

An apparatus includes a body extending from a first end to a second end. The first end is a leading end, and the second end includes a first coupling element configured to couple the body to a first other component. The body includes an external fixation element extending along a length of the first component. The external fixation element is configured to engage bone. Systems and methods are also disclosed.

Disclosed herein is an implant. The implant can include a body and a plurality of fixation members. The body can define an articular surface and a bone engaging surface opposite the articular surface. The bone engaging surface can define a groove that separates a first section of the bone engaging surface from a second section of the bone engaging surface. The plurality of fixation members can extend from the bone engaging surface.

A system and method for improving upon an ability of a surgeon to repair traumatic bone injury using new materials, components, and structures. A structure may be used as an implant or a component of an external fixator for a fractured long bone with that structure having anisotropic and viscoelastic properties, such as through additive manufacturing techniques.

Disclosed herein is an implant. The implant can include a body and a plurality of fixation members. The body can define an articular surface and a bone engaging surface opposite the articular surface. The bone engaging surface can define a groove that separates a first section of the bone engaging surface from a second section of the bone engaging surface. The plurality of fixation members can extend from the bone engaging surface.

A tool for locating the insertion point of a radial component of a wrist prosthesis on a human distal radius bone, the guide comprising a handle; a guide face attached to the handle, the guide face being of a shape configured to engage an articular surface of the distal radius bone; the guide face comprising three visual cues respectively adapted to align with a palmar corner of a radio-ulnar joint located on the distal radius, a dorsal corner of a radio-ulnar joint located on the distal radius, and a tip of a radial styloid located on the distal radius; the guide face further comprising an opening designating the insertion point, the opening being at a designated location on the guide face relative to the visual cues; and the opening adapted to facilitate the marking of the insertion point on the articular surface of the distal radius bone.
