The most challenging
aspects of performing a
shoulder replacement
involves accessing and
viewing the glenoid,
according to Dr.
Horneff. Pneumatic or

rotation with abduction to help the humerus fall [away from the field],"
comments Dr. Horneff. "Arm positioning aids make that so much easier to
do."
