Abstract
A compression hip screw for repairing a bone fracture includes a non-absorbable plate and a non-absorbable barrel section connected to the plate adapted to be inserted into a hole formed in the hip bone. A non-absorbable lag screw with a longitudinal opening therein and with internal and external threads is adapted to be inserted through the longitudinal opening in the barrel and into the portion of the bone on one side of a fracture. A compressing screw with threads adapted to cooperate with the internal threads of the lag screw and a head adapted to abut the outer portion of the barrel adjacent to the longitudinal opening can be inserted into the opening in the barrel for compressing the portions of the bone on both sides of the fracture. The compressing screw has at least a head portion formed of a material that absorbs on contact with body fluids.
