Reverse shoulder prosthesis UNIC®

cementless

The reverse total shoulder (TSR) is indicated when both sides of the shoulder joint are worn out and associated to an extended and irreparable lesion of the rotator cuff. In this indication, the glenoid bone stock must allow the fixation of a prosthetic glenoid base. The UNIC system is characterized by: an orientation of the humeral cup increased by 8° compared to the humeral resection cut a reduced cup diameter to sphere diameter ratio a multiple position fine tuning of the cup on the stem unabling proper arm lateralization and deltoid muscle tension a glenoid base bone anchoring based on an helical non-traumatic blade which is designed to resist sheer stresses
