[Structure and solidity of new bone in a cortical gliding hole by implanted leg screw (author's transl)].
Leg screws were implanted in 30 tibia diaphysis. 112 days later in the gliding hole there was new lamellar bone round of the screw head, neck of screw and into the both first screw threads. After screw explantation we measured in 8 cases the solidity of the new bone. Under conditions of tension measurement, we use 341 N per millimeter cortical thread surfaces to put out all new bone from the gliding hole. The results of these tension measurements were cylindric fragments. The remodelling into the gliding hole seems to be the results of static stress and dynamic compensation for reaching a defect in living cortical bone.
