Abstract: A ceramic implant having a rough surface texture and a method for forming the same. The method includes forming a green body of a first ceramic composition. The green body is reduced to smaller pieces thereby forming ceramic fragments. A mold is filled with a second ceramic composition to form a ceramic base. Ceramic fragments are added to the mold and an outer layer is formed over at least a portion of the ceramic base. Pressure is applied to the mold to compress the outer layer onto the ceramic base and to form a green assembly. The green assembly is sintered to form a ceramic implant having a rough surface texture.

The guiding element has a preoperatively configured orientation and location relative to the patient-specific portion for preparing a bore in the bone of the patient to direct a bone screw at the preoperatively configured orientation and location for sacroiliac fixation.

Abstract: A method for preparing an implant having a porous metal component. A loose powder mixture including a biocompatible metal powder and a spacing agent is prepared and compressed onto a metal base. After being compressed, the spacing agent is removed, thereby forming a compact including a porous metal structure pressed on the metal base. The compact is sintered, forming a subassembly, which is aligned with a metal substrate portion of an implant. A metallurgical bonding process, such as diffusion bonding, is performed at the interface of the subassembly and the metal substrate to form an implant having a porous metal component.

Abstract: A prosthetic wrist having at least one of a radial insert, which is configured to be fixed to a radius of a patient, a carpal implant or a wrist bearing component. The carpal implant can include a body and a pair of flanges, each of which being skewed to the axis of the body in a manner that permits them to abut the ulnar side of the hamate bone and the radial side of the distal portion of the carpal bone complex, respectively. The radial insert may be provided with a plurality of modular portions to allow for selection and customization of an implant. Also the various portions can allow for a hemi- or total, or revision wrist arthroplasty. The modular portions can allow for intraopertative customization.

Abstract: The joint implant manufacturer obtains and compiles surgeon-specific surgical and supply preference information in relation to a supplied joint implant prior to surgery. The manufacturer designates and trains at least one surgical team member using the surgeon-specific preference information and then supplies the service of the surgical team member(s) together with the supplied joint implant and supplies. The surgical team member(s) perform surgical procedures on the patient to assist the surgeon in removing a defective joint and replacing it with the supplied implant in accordance with the surgeon's surgical preferences.

Abstract: A pelvic implant includes a first surface including a recess configured for receiving a portion of a flange of an acetabular cage and a patient-specific second surface opposite to the first surface. The patient-specific second surface is preoperatively configured from a three-dimensional digital image of a pelvis of a patient to mate and closely conform to a corresponding surface of the pelvis under the flange in only one position.

Abstract: A system and method of implanting a distal wrist implant relative to a host bone is presented. A distal radial component having a body including a first connection portion couplable to a stem is coupled to a second prosthetic coupled to a medial surface of the body. The second prosthetic replaces at least a portion of the sigmoid notch.

Abstract: A modular prosthesis system for replacement of a head portion of a proximal radius includes a monolithic stem component, a head component, and a locking mechanism formed by the stem and head components. The stem component defines a stem anchoring portion having a longitudinal axis and configured to couple to the proximal radius, and a dovetail-shaped first mounting portion on a first end face that extends in a first direction transverse to the longitudinal axis. The head component has a dovetail-shaped second mounting portion on a second end face opposite the first end face slidably engaged with the first mounting portion along the first direction. One of the first and second mounting portions intersects the longitudinal axis. The locking mechanism is formed at an interface between the stem and head components and is engaged through relative translational movement between the stem and head components. A related method is provided.

The implant sleeve includes a proximal end, a distal end, an annular sidewall, a mesh portion of the annular sidewall, and an interior area. The annular sidewall is between the proximal end and the distal end. The mesh portion defines a plurality of openings in the annular sidewall. The interior area is defined by the annular sidewall and is configured to receive a stem of the implant. A longitudinal axis of the implant sleeve extends along an axial center of the interior area. In response to force applied to the implant sleeve, the implant sleeve compresses and the mesh portion expands outward from the longitudinal axis.

Abstract: A method for preparing a backup kit for a plurality of patient-specific arthroplasty procedures scheduled at the same medical facility includes providing a database with data from completed arthroplasty procedures using patient-specific arthroplasty kits. The database includes comparisons between preoperatively planned implant size and intraoperatively implanted implant size. The method includes determining a statistically expected implant size deviation from a planned implant size for each implant included in a plurality of patient-specific arthroplasty kits prepared for a shipment to the medical facility using the database. A backup kit of backup implants is assembled for the shipment. The number and size of the backup implants is determined from the statistically expected implant size deviations.
