STEMLESS REVERSE HUMERAL IMPLANT SYSTEMS
A humeral component of a prosthetic assembly that is used in repairing or reconstructing a joint between a humerus and a scapula that includes a stemless portion and a liner portion. The liner portion is attached to the stemless portion and adapted to receive a ball portion of a cooperating “reverse” type glenoid component.
1 . A humeral component of a prosthetic assembly for use in repairing or reconstructing a joint between a humerus and a scapula by cooperating with a ball portion of a glenoid component that is adapted for attachment to the scapula, said humeral component comprising:
a stemless portion having a proximal end and a distal end, said distal end of said stemless portion being adapted for insertion into the humerus;
a liner portion that is adapted to receive the ball portion of the glenoid component, said liner portion being attached to the proximal end of the stemless portion;
an insert portion having a proximal end and a distal end, said proximal end adapted to accept a fastener and said proximal end adapted for insertion into distal end of stemless portion;
a fastener portion having a proximal end and a distal end, said distal end adapted for insertion through proximal end of stemless portion.
