Scapular anchor for fixing a glenoid component of a shoulder joint prosthesis to a scapula with compromised anatomy

A scapular anchor for fixing a glenoid component of a shoulder joint prosthesis to a patient's scapula with compromised anatomy, comprising:

• a glenoid support defined by a pin for fixing said glenoid component to said scapular anchor and by a flange integral with said pin, said flange having a distal surface adapted to be at least partially in contact with a glenoid cavity of a scapula and a proximal surface opposite said distal surface;
• wherein said scapular anchor comprises at least one customized portion specifically shaped with respect to a bone morphology of the scapula of a single patient with compromised anatomy;
• wherein said at least one customized portion comprises at least one customized coracoid support projection arranged to abut at a coracoid process of said scapula and having a substantially tubular shape having a proximal end adjacent to said glenoid support and a distal end adapted to abut to said coracoid process of said scapula;
• wherein said at least one customized coracoid support projection is made in one piece with said glenoid support;
• wherein a through-hole extends between said proximal end and said distal end of said at least one customized coracoid support projection, for inserting a stabilization bone screw into said coracoid process of said scapula.
