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.
