A modular reverse shoulder prosthesis, comprising: a stem () comprising a tapered body () and a first annular housing (); a tray () comprising a dome element () for insertion into the first annular housing (), and further comprising a second annular housing (); a liner () comprising an engaging element () for at least partial insertion into the dome element (), and further comprising a joint concave element () configured for coupling with the second annular housing (). The second annular housing () of the tray () comprises a raised edge () configured to support the joint concave element () and which defines an overall outline having a different development in height at least in diametrically opposite portions () of the tray ().

Modular reverse shoulder prosthesis

The present invention relates to a shoulder prosthesis comprising:—a metaglene element () or baseplate;—a pin () projecting from said metaglene element ();—a through-hole () in the centre of said metaglene element ();—at least one through-hole () formed in a periphery of the metaglene element () with respect to said central through-hole ();—a glenosphere element () opposite said pin () with respect to said metaglene element ();—a central compression screw () housed in said through-hole () in the centre of said metaglene element () and having a head abutting onto the bottom of said hole (); and—wherein the central through-hole () has an opening (A) that is threaded in a stretch to receive the end of a safety screw () passing through the glenosphere element ();—a connector element () between the metaglene element () and the glenosphere element (), the metaglene element () providing a seat () for housing the connector element () projecting around the central through-hole ().

Shoulder prosthesis

The present invention relates to an improved glenoid adapter for shoulder prostheses, in particular for the conversion of an anatomic resurfacing prosthesis to a reverse shoulder prosthesis, comprising: &#x2022;&#x2014;at least one fixing projection () having an own axis (X) and being arranged to be fixed to the glenoid cavity () of the scapula () &#x2022;&#x2014;a flange () integral with said fixing projection (); &#x2022;&#x2014;an attachment portion () integral with the flange () and extended in the direction opposite said fixing projection (), as well as arranged to be coupled with an articular component () of reverse prosthesis provided with a convex articular surface (), said attachment portion () having an own longitudinal axis (Y); both the fixing projection () and the attachment portion () have truncated-cone shape and that the axis of the attachment portion (Y) is misaligned with respect to the fixing projection axis (X); said flange () has a glenoid surface () from which said fixing attachment () rises.

Glenoid adapter for shoulder joint prosthesis

Prosthesis element

The invention relates to a method for surgical application of a glenoid anchor of a shoulder joint prosthesis and instruments advantageously used in the method. The method includes making a delto-pectoral incision providing a delto-pectoral access to a shoulder joint; with the delto-pectoral access being suitable for inserting at least one machining tool; and making a trans-deltoid incision providing a trans-deltoid access to the humeral head; with the trans-deltoid access being suitable for inserting a stem of a machining instrument to be mounted on the machining tool for machining the glenoid cavity.

Method for surgical application of a glenoid prosthesis component of a shoulder joint prosthesis and relating surgical instruments

The present invention relates to an improved glenoid anchor for a shoulder joint prosthesis, in particular a convertible prosthesis, of the type intended to be fixed to the glenoid cavity of the shoulder blade and comprising: &#x2014;a pin () with an internally hollow and essentially thimble-like conical sleeve (), which has a tapered distal end () and an open proximal end (); &#x2014;an annular recess () formed inside the cavity () of the pin () in the vicinity of said open proximal end (), for receiving by means of snap-engagement an edge () of a lug () of a prosthesis component (); &#x2014;at least one pair of oppositely arranged anti-rotation notches () in the proximity of said annular groove () for receiving by means of snap fit oppositely arranged teeth () of the same lug () intended to be snap-engaged together with said pin ().

Apparatus and methods for total elbow replacement are provided to allow a surgeon to intraoperatively select a linked or unlinked constraint by utilizing a connection located on the body of the ulnar and/or humeral stem. Additional modularity also allows the selection of a cemented or cementless stem as described herein. The modularity and adjustability provides a number of advantages.
