Implant module and method for repairing avulsion fracture

A method for repairing an avulsion fracture, for dragging a bone fragment toward where the bone fragment tears from a bone, the method comprising:

• forming a first through hole in the bone fragment, and forming a second through hole in the bone, wherein the second through hole penetrates the bone and is connected to where the bone fragment tears from the bone;
• screwing a screw to the bone fragment from a side adjacent to where the bone fragment tears from the bone, wherein a first section of the screw is fixed to the bone fragment;
• and
• screwing a stud to the bone from a side far away from where the bone fragment tears from the bone, wherein the stud with a second external thread on an outer surface thereof is screwed with the second through hole of the bone, and an end of the stud has a screw hole screwed with a first external thread on a second section of the screw, to drag the bone fragment toward where the bone fragment tears from the bone.
