The invention relates to a modular humeral prosthesis for an inverse shoulder prosthesis, comprising an anatomical shaft () and a separable epiphyseal head () which may be angularly orientated by rotation about the longitudinal axis (XX) of the anatomical shaft. The anatomical shaft and the epiphyseal head comprise complementary angular indexing means () for relative rotational fixation.

Modular humeral prosthesis for an inverted shoulder prosthesis

A humeral component of a reverse shoulder prosthesis includes a stem part configured for location within the intramedullary cavity of the humerus, the stem part having a stem axis, an epiphyseal part connected to the elongate stem part and having a concave bearing surface defining an epiphyseal axis, and wherein the epiphyseal axis is offset posteriorly relative to the stem axis.

Humeral component of a shoulder joint prosthesis

A method of installing a prosthesis assembly includes installing a base component in a prepared glenoid vault, axially aligning a plurality of slots in one of a stretched glenoid bearing component and a base component with a plurality of ridges in the other of the glenoid bearing component and the base component, each of the plurality of slots having a maximum length which is greater than a maximum length of a respective one of the plurality of ridges, engaging each of the plurality of ridges with the respective one of the plurality of grooves thereby rotatably coupling the glenoid bearing component and the base component and limiting axial movement of the glenoid bearing component relative to the base component, and placing the bearing surface into articulating contact with a humeral head.

This technology relates to a one-piece sleeve which envelops a chamber with a baffle in a firearm suppressor body. The one-piece sleeve has an elongate opening, or slot, extending longitudinally along all, or part of, the length of the sleeve. The slot may be straight or curved. Also, there may be a plurality of slots. This way, because of the slot(s), the sleeve has increased flexibility and may be easily slightly opened up, and more easily removed from the elongate suppressor body for cleaning.

A method for retraction useable in joint arthroplasty. The method includes using a joint retractor having a first arm and a second arm. The first arm has a first portion and a second portion and the second arm having a first portion and a second portion. The retractor is inserted into a surgical opening of a patient's shoulder joint. The second portion of the first arm is placed against the coracoid process and the second portion of the second arm is placed against the resected humerus. The first portions of the first and second arms are hung over the resected tissue to allow exposure of the glenoid.

Spreading retractor

A prosthesis assembly configured for use with a scapula in one embodiment includes a spherical humeral component, an elongated glenoid bearing including a first bearing surface with (i) a first spherical end portion with a first radius of curvature, (ii) a second spherical end portion with a second radius of curvature, and (iii) a central portion located between the first spherical end portion and the second spherical end portion, and a first coupling portion extending from a second bearing surface opposite the bearing surface, and a base configured to rotatably support the elongated glenoid bearing, wherein the first radius of curvature is substantially equal to the second radius of curvature and the central portion does not have a radius of curvature that is substantially equal to the second radius of curvature.

A one-piece sleeve which envelops a chamber with a baffle in a firearm suppressor body is disclosed. The one-piece sleeve has an elongate opening, or slot, extending longitudinally along all, or part of, the length of the sleeve. This way, because of the slot, the sleeve has increased flexibility and may be easily slightly opened up, and more easily removed from the elongate suppressor body for cleaning.

One-piece sleeve for firearm noise suppressor

A spreadable retractor for use in joint arthroplasty. The retractor includes a first arm having a first portion and a second portion that is movably coupled to the first portion. The second portion is also coupled to a first retaining member that is sized and shaped to retain a portion of a coracoid process. A second arm is also included in the retractor and is movably coupled to the first arm. The second arm has a first portion and a second portion that is movably coupled to the first portion. Also, the second portion is coupled to a second retaining member that is sized and shaped to couple to a resected humerus.

A medical procedure includes providing a prosthesis which includes (i) a body portion having a rear surface and a bearing surface, and (ii) an anchor peg including a shaft extending from the rear surface of the body portion, wherein the anchor peg includes a plurality of outwardly extending fins secured to the shaft, and further wherein the plurality of outwardly extending fins each possesses a first diameter. The medical procedure further includes creating an anchor hole in a natural bone, the anchor hole possessing a second diameter which is less than the first diameter. In addition, the method procedure includes positioning the anchor peg within the anchor hole so that each of the plurality of outwardly extending fins deforms so as to possess (i) a concave side which faces an open end of the anchor hole, and (ii) a convex side that faces a closed end of the anchor hole.

Method for securing a glenoid component to a scapula

A glenoid component for securement to a glenoid surface of a scapula so as to provide a bearing surface for a head portion of a humerus includes a body portion having a first surface configured to contact the glenoid surface of the scapula and a second surface configured to receive the head portion of the humerus. The glenoid component also includes an anchor peg extending from the first surface of the body portion for penetrating the glenoid surface of the scapula so as to secure the body portion to the glenoid surface of the scapula. The anchor peg has a first end portion and a second end portion with the first end portion of the anchor peg being secured to the first surface of the body portion, and the second end portion of the anchor peg having a number of fins secured thereto. The glenoid component also includes a first stabilizing peg extending from the first surface of the body portion for penetrating the glenoid surface of the scapula so as to prevent movement of the body portion relative to the glenoid surface of the scapula. A method of securing a glenoid component to a glenoid surface of a scapula so as to provide a bearing surface for a head portion of a humerus is also disclosed.
