REVERSE SHOULDER SYSTEMS AND METHODS

摘要

Reversed glenoid implants, and related kits and methods, are described that include an anchor member having a proximal head and a baseplate having a distal end with a first aperture sized to accept the proximal head of the anchor member. The proximal head is inserted along an un-threaded length thereof from the distal end into the first aperture, and the anchor member is restrained against axial translation with respect to the baseplate but is permitted to rotate with respect to the baseplate.

主权项

1. A glenoid implant for a shoulder prosthesis comprising:
an anchor member comprising a longitudinal portion configured to be secured to a bone and a proximal head comprising an external threaded surface; a baseplate comprising a proximal end and a distal end, wherein the distal end comprises a first aperture sized to accept the proximal head of the anchor member, the first aperture comprising an internal threaded surface and a space disposed proximal of the internal threaded surface; wherein when the external threaded surface of the proximal head is disposed proximal of the internal threaded surface of the first aperture the anchor member is restrained against axial translation with respect to the baseplate but is rotatable with respect to the anchor member.
