Placed at the top of the fossa
The roof of the glenoid fossa is often crisper than the condyle inside it. It is the socket, not the head.

Common errors
Each figure is the reviewed reading of Condylion (Co) and a typical miss, on the same ceph, at the distance the mistake usually goes.
Placed at the neck
Where the head is invisible the point falls to the last clear outline, which is the narrower neck below it.
Used in
