The transverse body has a first side configured to engage scapula bone of a patient, a second side configured to face away from the first side, and a plurality of anchor apertures. The anchor apertures are formed between the first side and the second side. The transverse body also can have an arcuate or circular periphery that has an anterior portion configured to be oriented toward an anterior side of a scapula and a posterior portion that is configured to be oriented toward a posterior side of the scapula. The elongate body is disposed along a longitudinal axis between an end coupled with the first side of the transverse body. The longitudinal axis of the elongate body is off-set from the center of the circular periphery.

Abstract: This set comprises glenoid components that each include a body defining, on two of its opposite faces, respectively, a joint surface, intended to cooperate with a humeral head, and a bearing surface bearing against the socket of a shoulder blade. In this set, the glenoid components are provided in several different sizes, respectively defined by the dimensions of the joint surface of their body. At least two glenoid components of which the bearing surfaces respectively have different dimensional geometries are provided so as to allow the surgeon to improve the durability of the mechanical cooperation between the implanted component and the operated socket.

Abstract: A bone press includes a base; a compression plate located opposite to the base; a housing that extends between the base and the compression plate, the housing extending along a longitudinal axis of the bone press; a pressing zone within the housing and between the base and the compression plate along the longitudinal axis of the bone press; and an actuator to provide relative movement between the compression plate and the base to create compression in the pressing zone.

Abstract: A method of guiding a glenoid prosthesis is disclosed. The method includes pre-operatively determining a position and an orientation of a guide feature of a glenoid guide of the present disclosure based on a scapula of a specific patient, and engaging the glenoid guide with the scapula; and inserting a pin having an axis through the guide feature to or through the scapula.

Abstract: Method and set of surgical instruments for fitting a shoulder prosthesis, and the shoulder prosthesis. The proposed method seeks to interpose a bone graft between the previously prepared glenoid surface (G) of a scapula (S) of a patient's shoulder and the face of a glenoid prosthetic component opposite the articular surface. The set of instruments permit the bone graft to be taken from the upper epiphysis of the humerus (H), either in situ or ex vivo.

Abstract: A patient specific glenoid guide is provided to facilitate properly aligned implantation of a glenoid prosthesis into a patient. The guide shape is designed preoperatively based on the unique configuration of the scapula of the patient. The guide orientation is chosen preoperatively based on one or more of the bone structure of the patient, the wear pattern of the patient's glenoid cavity, the anchoring means of the glenoid prosthesis, or other aspects.

Abstract: Provided is a method of resecting a humerus, including positioning a multi-part guide on the humerus, where the multi-part guide includes a support portion and a positioning jig; advancing at least two mounting pins through the support portion along diverging paths; removing the positioning jig; and resecting the humerus with reference to a cutting surface of the support portion.

Abstract: Embodiments of the present invention include a convertible prosthesis that is capable of conversion from a humeral head replacement to a reverse reconstruction without any removal of parts integrated into the patient's bony anatomy (e.g. implant stems). A desired overall implant inclination angle may be achieved by matching various implant stems with various reverse inserts, thus permitting a resection surface to be matched with an implant stem selection while also permitting a desired overall implant inclination angle to be achieved through the selection of an appropriate insert.

Abstract: Various apparatus and methods for implanting glenoid prostheses are disclosed. In various embodiments, a method for performing shoulder surgery can include guiding a guide pin into the glenoid surface along a reaming axis. A partial reaming guide can be placed in contact with the glenoid surface over the guide pin. A reamer can be guided over the guide pin to ream the glenoid surface. The reamer can be further advanced over the guide pin until the reamer contacts the partial reaming guide, whereby such contact limits reaming to only a portion of the glenoid surface.

Abstract: A glenoid implant for a shoulder prosthesis for implantation in the glenoid of a scapula according to embodiments of the present invention includes a central fixation element; an articular body configured for articulation with a humerus, the articular body comprising a plate, the plate comprising a side configured to be oriented toward the glenoid, the side comprising a central protrusion, wherein the central fixation element comprises a means for mechanically engaging with the central protrusion; a first means for locking rotation of the central fixation element with respect to the glenoid; and a second means for locking rotation of the articular body with respect to the glenoid.

Abstract: A humeral guide is provided that has a first portion or member configured to be positioned on a portion of a proximal humerus. The first portion or member can be configured to rest in a complementary manner on the portion of the proximal humerus. The humeral guide can be configured with apertures defining trajectories through bone, the pin trajectories being diverging in some case and in some cases being selected to enhanced support. A second portion or member and a third portion or member of the humeral guide are configured to be positioned on first and second lateral portions of the humerus distal to a location intended for resection, e.g., between an anatomical neck and a distal end of the humerus. The second and third portions or members or portions are configured to rest in a complementary manner on the first and second lateral portions of the humerus. The humeral guide can be configured to avoid soft tissue between a bone facing side and the humerus. The humeral guide can have a removeable jig portion.
