Abstract

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.

A method for surgical application of a glenoid anchor or a glenoid prosthesis component of a shoulder joint prosthesis, comprising:

making a delto-pectoral incision providing a delto-pectoral access to a shoulder joint, the shoulder joint comprising a humeral head of a humerus facing a glenoid cavity of a shoulder blade;
inserting a machining tool in the delto-pectoral access;
making a trans-deltoid lateral incision providing a trans-deltoid lateral access to the humeral head;
inserting a stem of a machining instrument in the trans-deltoid lateral access;
mounting the machining tool on the stem of the machining instrument;
and
machining, with the machining tool, the glenoid cavity.
