see buttress thread bone screw.
buttress thread bone screw
the thread is not a simple V as in the standard thread but has one side of the groove at right angles to the direction of the screw and the other side at a 45° angle. Called also AISF, Howmett compression, Richards-Bechtol.

has a coarse thread; threaded to only the first third of the length of the screw.

Howmett compression bone screw
see buttress thread bone screw.
lag bone screw
used as a compressing unit between two fragments with the first half of the screw near the point threaded, with the diameter of the ridges greater than that of the unthreaded half near the head. As the ridged part of the screw bites in the walls of the drill hole in the distal fragment, the unthreaded part is free to move within the drill hole in the proximal fragment, thus compressing the two pieces of bone together.
Richards-Bechtol bone screw
see buttress thread bone screw (above).
standard bone screw
with a V thread the full length of the screw, with a single slot, cruciate or Phillips head.
transfixation screw
orthopedic screw used to reattach bone fragments to a solid skeletal part. The proximal part near the head is not threaded and needs to be of a smaller diameter than the threaded portion nearer the tip.
