摘要：
A reverse shoulder joint prosthesis (1) for location between a humerus and a scapula comprised a ball (5) to be fixed to the scapula and a humeral stem 6 to be fixed to the humerus. The prosthesis comprises a first cup (2), a second cup (3) and a plate (4) retained between said cups. The first cup is free to move about the ball. The plate has a trunion (16) adapted to connect to the humeral stem through an aperture in the second cup. The plate is free to move between the cups. The prosthesis has a first phase of movement in which the plate moves between the cups and a distinct second phase of movement in which the first cup moves on the ball. The shoulder joint prosthesis provides an extended range of movement through the provision of two motion phases while minimising wear, scapula infringement and instability.
