"The non-spherical prosthetic head
replicated the native head shape
more accurately than the spherical
prosthetic head."

An Inlay Glenoid is
10 times more stable
than an onlay glenoid.
"The study suggests that the humeral head is not a
perfect segment of a sphere and an osteotomy
along the anterior cartilage-metaphyseal inter-
face does not remove only the proximal humeral
articular surface. Even with a fully adaptable
prosthetic implant, replacement arthroplasty
is not able to restore original head geometry.
Alterations to head geometry with the osteotomy
described may alter the line of force through the
prosthetic joint, producing eccentric loading at
the glenoid, and contribute to early failure."
