Tornier Perform Reversed Glenoid Glenosphere - Reverse shoulder prosthesis head

Intended purpose

A component of the Tornier Perform Reversed Glenoid system intended for replacement of the glenoid part of the scapulohumeral joint as part of a reverse shoulder prosthesis. The system is intended to reduce pain and improve shoulder mobility, in comparison with preoperative status, in patients with a functional deltoid muscle and with a massive and non-repairable rotator cuff-tear.

Functional description

A hemispherical component of the Tornier Perform Reversed Glenoid System intended to be attached to the baseplate to articulate with a congruent reverse shoulder insert. The glenosphere is made of Cobalt Chromium alloy and contains a morse taper connection that mates with a taper on the baseplate components. It also includes assembled subcomponents that make up a captured locking screw used as secondary locking mechanism to lock the glenosphere onto the baseplate in addition to the taper.
