Abstract: An external fixation system for treatment of bones includes first and second clamps for locking pins that are inserted into bones. At least one clamp includes a socket having a recess. An attachment post includes a distal portion configured to be inserted into the socket recess. A tightening nut is rotationally coupled to a shaft of the attachment post and has an internal threading adapted to be threaded to the external threading of the socket. When the tightening nut is rotated to cause the distal portion of the post to be further inserted into the recess, the sides of the distal portion of the post create an interference fit with the sides of the socket recess to lock the post to the first clamp.

Abstract: A bone plate includes at least one variable angle locking hole that is configured to threadedly mate with a variable angle locking screw oriented so as to define any angle among a range of angles with respect to a central axis of the VA locking hole at which a threaded head of the locking screw is configured to threadedly purchase with the bone plate in the variable angle locking hole.
