The effect of different methods of preparation of glenoid bone on
displacement and deformation of a glenoid component under eccentric loading
was investigated in a series of scapulae of cadavera. Handburring of the
osseous surface was associated with less displacement and deformation than
simple removal of cartilage with a curet. Reaming resulted in the least
displacement and deformation. Substantial posterior deficiency of the bone
of the reamed glenoid was not associated with significant increases of
displacement and deformation.
