Scapular anchor for fixing a glenoid component of a shoulder joint prosthesis to a scapula with compromised anatomy and related method for manufacturing said scapular anchor

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, said glenoid support being 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;
• 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, said at least one customized coracoid support projection being made in one piece with said glenoid support;
• a through-hole extending between said proximal end and said distal end for inserting a stabilization bone screw into said coracoid process of said scapula;
• at least one customized acromial support projection arranged to abut at an acromion process of said scapula, wherein said at least one customized acromial support projection has a substantially tubular shape having a proximal end adjacent to said glenoid support and a distal end adapted to abut to said acromion process of said scapula, wherein a through-hole extends between said proximal end and said distal end for inserting a stabilization bone screw into said acromion process of said scapula, wherein said at least one customized acromial support projection is made in one piece with said glenoid support;
• at least the distal surface of said flange being a customized distal surface of said flange, said customized distal surface being complementary shaped with respect to the glenoid cavity of said scapula.
