  • Patent number: 5147367
    Abstract: A drill pin guide and method is disclosed for the fixation of bone fractures. A surgeon first inserts a small orthopedic pin through a bone fragment into the underlying bone mass to stabilize the fracture. Next a drill guide is placed over a portion of the pin protruding from the bone and is used to position a drill bit for drilling a small hole parallel to the inserted pin. After removing the drill pin guide a surgical screw is inserted into the drilled hole. By properly adjusting the distance between pin and screw, the surgeon may create an interference fit between the two thus preventing either from unintentionally loosening.
