A bone fixation screw system and method of utilization thereof is provided for a bone having first and second sections with a fracture interface there between. A preferred embodiment of the bone fixation screw system includes a side plate having a first part for placement adjacent the bone second section and a second part angled from the first part providing a barrel. The barrel is adapted for insertion into a transsectionally extending bore into the bone in at least the second section of the bone. A lag screw is also provided for positional retention of the first section of the bone with respect to the second section of the bone. The lag screw also has a first part of a resorbable material for threaded connection of the lag screw within the bore of the bone in at least the first section of the bone, the lag screw having a second part connected with the first part made from a stronger nonresorbable material. The present invention also provides a bone screw having a resorbable material for a threaded first part. The bone screw first part is connected to a nonresorbable bone screw second part.
[ What is claimed is:] [1.] A bone screw comprising:a first part of a resorbable material for threaded connection of the bone screw within a bone, said first part having a first mating surface; anda second part made from a stronger non-resorbable material, said second part having a second mating sur
[ What is claimed is:] [1.] A bone screw comprising:a first part of a resorbable material for threaded connection of the bone screw within a bone, said first part having a first mating surface; anda second part made from a stronger non-resorbable material, said second part having a second mating surface, said first mating surface and said second mating surface each having mating contoured surfaces, said first mating surface is torsionally locked with said second mating surface and said first mating surface is axially locked with said second mating surface in a first axial direction and a second axial direction, whereby torsional and axial movement of said first part relative said second part is inhibited.
