Abstract
An interlocking interface retains a screw head in a socket to prevent migration of the screw head out of the socket, or to lock the screw head in the socket. The interlocking interface may retain or lock the screw at various polyaxial angles with respect to the socket. The screw head includes external corrugations. The socket includes an internal corrugated structure which interlocks with the external corrugations of the screw head when the screw is at various polyaxial angles with respect to the socket.
Claims19
A locking connection comprising:
- a polygonal socket comprising internal corrugations;
- and
- a head received in the socket, the head comprising external corrugations;
- wherein the external corrugations engage the internal corrugations at any of a plurality of orientations of the head relative to the socket.

A locking connection comprising:
- a polygonal socket comprising alternating internal peaks and valleys;
- and
- a head coupled to the socket, the head comprising alternating external peaks and valleys;
- wherein the external peaks and valleys engage the internal peaks and valleys at any of a plurality of angles of the head relative to the socket.
1 more element
A locking connection comprising:
