About

Scapular notch can be reduced by using bigger glenospheres but in some patients it cannot be implanted because of small size. If small size of glenosphere is used then scapular notch may increase. To improve that situation, eccentricity has been added to some glenospheres to increase glenoid overhanging. The objective is to assess if eccentricity can avoid scapular notch as effectively as bigger glenospheres.
