METHOD FOR TWO-STAGE SURGICAL TREATMENT OF SPINAL DEFORMITY WITH USING AUTOPRESERVED RESECTED AUTORIB AND DRY VERTICAL HALOTRACTION Russian patent published in 2014 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: ventral release is performed at an apex of deformity from a thoracotomic approach. That is followed by a discectomy and resection of arch laminae with interbody spaces filled with a haemostatic sponge. A seventh, or an eight, or a ninth rib for an autograft are resected. The autograft is placed in subcutaneous fat and fixed to the underlying tissues. A pleura, muscles and fascias are closed. On the 2^nd-3^rd day following the completion of the first stage, a dry halotraction is performed till the stage of a dorsal spinal. A sterile halo-ring is placed on a patient's head; the ring comprises threaded holes created in its body perpendicular to its axis; the threaded holes comprise mounted threaded metal screws that are halotraction rods with pointed ends. The halotraction rods are moved in the halo-ring holes, brought to skull bones and screwed into a cortical layer of the bone to a layer of an internal cortical plate. A pre-set halotraction session is performed. The autograft is removed through an incision in the postoperative scar from a pocket, cleaned from soft tissues and processed in an antiseptic solution. That is followed by a dorsal spinal correction with using metal fixing elements with the autograft placed on the decorticated posterior elements of the spine. An autograft portion is placed in the form of autochips on the decorticated posterior elements. The halotraction procedure involves the metal halo-ring made of titanium or its alloys, the halotraction rods and fixing elements.

EFFECT: preparing the adequate posterior spondylosyndesis with recovered configuration of the spinal canal.
