A system and method facilitating replacement of comminuted bone fractures or portions thereof adjacent bone joints. The system and method employs a prosthesis to replace at least a portion of the comminuted bone fractures. The prosthesis serves in reproducing the articular surface of the portion or portions of the comminuted bone fractures that are replaced. In doing so, the prosthesis serves in restoring joint viability and corresponding articulation thereof.

Stemless components and fracture stems for joint arthroplasty, such as shoulder arthroplasty, are disclosed. Also, methods and devices are disclosed for the optimization of shoulder arthroplasty component design through the use of medical imaging data, such as computed tomography scan data.

Provided is a method for manufacturing a prosthesis for a fractured long bone of a patient. The method includes: providing data representative of the fractured long bone of the patient, the fractured long bone comprising a diaphyseal fragment comprising a medullary cavity; based on the data provided, designing the prosthesis specifically to the patient, wherein the prosthesis comprising a stem part configured to be inserted into the medullary cavity for securing the stem part to the diaphyseal fragment.

Disclosed herein are an implant with a suture passage and a method of attaching sutures to the same. The implant may include a suture pocket having a first pocket, a second pocket, and a suture hole disposed therebetween. The first pocket may have a first wall segment, the second pocket may have a second wall segment, and the suture hole may have a first sidewall segment extending from a first opening to a second opening. The first wall segment, the second wall segment, and the first sidewall segment may form a contiguous wall. A method of attaching a suture to the implant may include placing a tip of a suture needle on the first wall segment, sliding the suture needle into the first opening and pushing the suture needle through the suture hole.

The invention concerns a method for manufacturing a prosthesis (11) for a fractured long bone of a patient, the method comprising the steps of: A) providing data representative of the fractured long bone, the fractured long bone comprising a diaphyseal fragment (2) comprising a medullary cavity (8); B) based on said data, designing the prosthesis specifically to the patient, the prosthesis comprising a stem part (12) configured to be inserted into the medullary cavity, step B) comprising: a sub-step of choosing, specifically to the patient, a contact zone (40) of the medullary cavity onto which a respective chosen mechanical stress is planned to be applied by the stem part, and a sub-step of designing the stem part so that the stem part may be inserted into the medullary cavity and thus apply the chosen mechanical stress to said contact zone; and C) manufacturing the prosthesis designed at step B).

A method of repairing a fractured bone may include implanting a prosthetic stem into an intramedullary canal of the fractured bone. First and second bone segments of the fractured bone may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the first end of the prosthetic stem. The first and second tuberosities may be machined so that the first and second bone segments 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 first end of the prosthetic stem, and the first interlocking surface interlocks with the second interlocking surface.

An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

A humeral prosthesis for replacing a proximal humerus includes a prosthesis body which includes a lateral surface, a medial surface, an anterior surface, a posterior surface, and a first superior surface. The lateral surface has a spherical curvature. The anterior and posterior surfaces are each planar and each intersect the first superior surface, the lateral surface, and the medial surface. A first bore extends through the first superior surface and into the prosthesis body. The prosthesis body also includes a plurality of suture openings.
