摘要

The implant has a plate (1) whose circular edge (1f) retains an insert co-acting with a hemispherical cup fixed in a glenoid cavity. The plate has a hollow anchoring rod (1a) with reduced height ranging about 10 to 20 mm, preferably 15 mm. The plate is engaged on a metaphyseal part of a humeral channel and humerus. The rod comprises peripheral openings (1c) to facilitate bone ingrowth. The circular edge comprises edge arrangements i.e. recessed notches (1f1, 1f2), co-acting with arrangements complementary to the insert to ensure angular indexing of the insert.
