A method of repairing a fractured humerus may include implanting a prosthetic humeral stem into a humeral canal of the fractured humerus. First and second tuberosities of the fractured humerus may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the proximal end of the prosthetic humeral stem. The first and second tuberosities may be machined so that the first and second tuberosities have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the proximal end of the prosthetic humeral stem, and the first interlocking surface interlocks with the second interlocking surface.

Shoulder arthroplasty systems and configurations for components thereof are described. For example, implant systems for a total should arthroplasty (TSA), hemi shoulder arthroplasty, and reverse should arthroplasty (RSA) are described. In addition, exemplary configurations for baseplates, glenoid components, glenosphere components, humeral components, humeral head components, humerosocket components, connectors, and adaptors, are described.

An implantable medical device is disclosed comprising a thermoplastic composite body having anterior, first lateral, second lateral, posterior, superior, and inferior surfaces, and at least one dense portion and at least one porous portion which are integrally formed. The at least one dense portion is formed of a first thermoplastic polymer matrix that is essentially non-porous, and which is continuous through a thickness dimension from the superior surface to the inferior surface. The at least one porous portion is formed of a porous thermoplastic polymer scaffold having a second thermoplastic polymer matrix which is continuous through the thickness dimension. A method for forming the thermoplastic composite body is disclosed comprising disposing a first powder mixture in a first portion of a mold, disposing a second powder mixture in a second portion of the mold, simultaneously molding the first powder mixture and the second powder mixture, and leaching porogen.

The invention features a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

A revision implant component comprising a body having a plurality of screw holes and a tapered head configured to engage a talar dome component of a multi-component ankle prosthesis. A surgical method is disclosed which includes creating an incision in a patient, exposing a multi-component ankle prosthesis implanted in a patient, disassembling at least one component of the multi-component ankle prosthesis, affixing a revision implant component to non-damaged bone using screws, and coupling the revision implant component to a talar dome of the multi-component ankle prosthesis.

Implantable drug-eluting device (1) comprising a microporous structure (2) having regularly arranged pores (4, 5) in at least two different uniform sizes, and manufacturing method. The pores are configured for receiving a drug (9) and are being connected by interconnections (6, 7). Interconnections (6) originating from pores (4) of a first size have a first elution area and interconnections (7) originating from pores (5) of a second size have a second elution area. The interconnections convey the drug (9) to a surface of the device for elution to surrounding tissue. The ratio between the first and the second elution areas is predefined and selectable. The differently sized elution areas provide for different outflow rates. This allows for simple but reliable dispensing of drugs at positively controlled and well determined rates. Particularly, this enables a single implantable device to dispense drugs over preselectable durations of time, like short-term or long-term.

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.

The present disclosure provides a bone-implantable device and methods of use. The bone-implantable device comprises a body having an exterior surface, wherein a portion of the exterior surface includes a cured osteostimulative material comprising MgO.

An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

In the present disclosure, an artificial joint stem includes a base including one or more grooves disposed on a surface of the base, and a coating film containing a calcium phosphate-based material and an antimicrobial material disposed on a part of the surface of the base. When among the one or more grooves, the groove located in a region where the coating film is disposed is defined as a first groove, and the groove located in a region where the surface of the base is exposed is defined as a second groove, a total length of the first groove is smaller than a total length of the second groove.
