A shoulder arthroplasty kit includes a humeral head component, a combination sizer and guide device substantially identical to the humeral component but including a including a guide bore, and a guide pin configured to be inserted into the resected surface of the humerus and configured to be guided by the guide bore to a center of the resected surface of the humerus which is covered by the at least one combination sizer and guide device.

A femoral prosthesis system for an orthopaedic hip implant and method of use is disclosed. The prosthesis system includes a femoral stem component that includes a core body and a casing that encases the core body. The casing can be additively manufactured such that the core body defines a predetermined orientation in the core body among a plurality of permissible predetermined orientations. The femoral stem component can further include a neck and a trunnion that extends from the neck. The neck can extend out with respect to the core body at a predetermined angle within a range of permissible predetermined angles.

Guides for guiding a tool into a medullary canal of a bone. The guides can include a base and a guide feature. The base can include a first surface configured to contact the bone and a second surface opposite the first surface. The guide feature can be disposed to guide the tool along a central portion of the medullary canal.

An orthopedic implant manufacturing method. The method includes preparing a pre-operative surgical plan for a specific patient, the surgical plan including a three-dimensional image of a patient's joint indicating at least one resection plane, communicating the surgical plan to a surgeon of the patient, and receiving approval of the surgical plan and the resection plane by the surgeon. The method also includes providing automated osteophyte/protrusion removal control for surgeon manipulation, receiving a modified three-dimensional image of a patient's joint indicating an osteophyte/protrusion removal and a recommendation for a corresponding selected orthopedic implant from the surgeon, and requesting manufacture of the selected orthopedic implant.

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 multi-member prosthesis including first and second elongated members and a central member, said multi-member prosthesis adapted to be advanced into a pilot SI joint opening in said dysfunctional SI joint via a posterior approach, the pilot SI joint opening comprising a sacrum opening and an ilium opening and a sacrum opening. The first elongated member adapted to be press-fit into the sacrum opening and the second elongated member adapted to be press-fit into the ilium opening. The central member including first and second elongated member securing means adapted to secure the first and second elongated members thereto.

Instruments, guides, systems and related methods for total ankle prostheses are disclosed. The instruments, guides, systems and related methods facilitate preparation of a tibia and/or talus of a patient for implantation of a total ankle prosthesis therein. The instruments, guides, systems and related methods also facilitate selection of a particular size of a tibial component, a talus component and/or a tibial insert of the total ankle prosthesis that suits the patient. The instruments, guides, systems and related methods include a tibial trial component, a talar trial component and tibial insert trial component that replicate one or more aspects of the tibial component, the talus component and the tibial insert, respectively, of the total ankle prosthesis. The talar trial component includes an articulation surface that articulates with the tibial insert trial component, and slots that facilitate chamfered resection of the patient's talus for the implantation of the talus component thereon.

A hemi-prosthesis implant comprises a replacement-joint part with an articulation surface for tribological pairing with a joint surface of a natural joint counterpart. The articulation surface is embodied with a coating applied on a substrate. The substrate provides a relief for the adhesion of the coating. The relief may comprise one or more of a plurality of grooves, a plurality of teeth, a ribbing, and a roughened surface. The relief may be embodied entirely or partially outside the articulation surface. The replacement joint part may optionally comprise a ventilation feature, and the articulation surface may be formed by injection molding on the substrate. The hemi-prosthesis implant may be part of an implant set that includes both a hemi-prosthesis implant and a total prosthesis implant, either of which can be chosen intraoperatively.

A tibial, prosthesis, and, particularly, a fixed bearing tibial, prosthesis has a two-pronged securement mechanism. The securement mechanism may or may not be angled. Advantageously, the securement mechanism, working alone or in cooperation with other securement features, minimizes micromotion between the tibial tray and tibial hearing component.

The system and method serves in 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.
