SYSTEM AND METHOD FOR SPINE STABILISATION USING WIRED PEDICLE SCREW Russian patent published in 2014 - IPC A61B17/70 A61B17/88 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine. A bone stabilisation system comprises a first screw with a first screw head, a second screw with a second screw head, a spinal fastener, at least a first guide element and at least a second guide element. The spinal fastener is provided to be kept in the first and second screw heads. At least the first guide element extends from the first screw and can pass through a skin hole through which it has been introduced. At least the second guide element extends from the second screw and can pass through the skin hole. The first and second guide elements can overlap, and if overlapped, guide the spinal fastener until it contacts the first and second screw heads at an angle formed by the guide elements, including an angle non-parallel with the long axis of the both guide elements. The above screw used for the bone stabilisation comprises a screw column, a screw head with a support and at least one wire. The above support limits a canal receiving the spinal fastener. at least one wire extends from the screw head and is configured so that to direct the spinal fastener into the canal of the screw head support.

EFFECT: group of inventions provides a simple method of placing two or more pedicle screws using a small hole, better cosmetic and functional results using only a single small skin incision (about one to two cm long) irrespective of the number of the used screw, and a possibility to insert, place and manipulate a rod and a locking mechanism through the same small incision for the purpose of locking the rod inside the screws.
