Locking screw
A screw with a threaded head designed to screw into and lock onto the threaded hole of the plate, rather than simply compressing the plate against the bone.
How it is used
Used with LCP (locking compression plates) and locked anatomic plates, fixed- or variable-angle, to provide angular stability in osteoporotic bone or multifragmentary fractures where conventional plate-to-bone compression is unreliable.
Clinical tip
Unlike a conventional screw, the locking screw fixes to the plate itself to form a fixed-angle construct, so perfect plate-to-bone contact is not required to maintain stability; some locked plates also accept conventional screws in the same holes or in combination holes.
