Abstract: Trials for a reverse shoulder system are described. The trials generally include an insert housed within a humeral cup. The insert has a proximal end and a distal end, the proximal end having a concave recess therein adapted to receive a glenosphere prosthesis. The distal end of the insert includes a shaft, the shaft is substantially housed within the confines of the humeral cup. A distal end of the humeral cup is inserted in a humeral stem.

Abstract: A bone screw apparatus is provided for threaded engagement with a bone and, optionally, a medical device such as a bone plate. The bone screw has a shaft having a first end, a second end, and a first thread having a first pitch. The screw further includes a head having a proximal end, a distal end adjacent the shaft first end, and a second thread having a second pitch. The second thread has a variable pitch that increases in a proximal direction, but never exceeds the magnitude of any portion of the first pitch. Upon threaded engagement of the head with bone or a medical device, a compression force is generated which continuously decreases as the screw is further inserted.
