Abstract A surgical wire and a method for the use thereof for interconnecting adjacent portions of bone structures are disclosed. The wire is preferably made of a flexible and malleable corrosion-resistant metal, such as a surgical grade of stainless steel, and it includes a main portion, a tapered portion which extends from the main portion, and a leader portion which extends from the tapered portion and has a substantially reduced diameter with respect to the main portion. The method is carried out by first threading the leader portion around a portion of a bone structure and then further advancing the leader portion to thread the main portion of the wire around the bone structure portion. The main portion of the wire is then secured to an adjacent portion of a bone structure to provide support for one of the two bone structure portions. The method has particular application in spinal surgery for interconnecting adjacent vertebrae to promote fusion of a fractured vertebra. In spinal fusion applications of the method, the leader portion is preferably connected to a curved surgical needle, and the needle is used for threading the leader portion through the spinal foramen of a vertebra along the underside of the lamina thereof so that damage to the spinal cord is avoided.
A surgical wire for interconnecting two or more adjacent portions of bone structures and the like in surgical procedures in order to provide support for one of said bone structure portions comprising an elongated substantially smooth flexible and malleable main portion of substantially circular cross section, a substantially smooth flexible and malleable tapered portion of substantially circular cross section which extends integrally from an end of said main portion, and a substantially smooth flexible and malleable leader portion of substantially circular cross section which has a substantially reduced diameter with respect to said main portion and extends integrally from the reduced end of said tapered portion.
