METHOD FOR TWO-STAGE SURGICAL MANAGEMENT OF SPINAL DEFORMITY USING AUTO-PRESERVATION OF RESECTED RIB AUTOGRAFT Russian patent published in 2014 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: first stage involves a ventral release at the top of the deformity from a thoracic approach, a sub-periosteal separation of the rib and a resection of a portion thereof by placing into an antiseptic solution. That is followed by a discectomy and resection of arch laminae with interbody spaces filled with a haemostatic sponge. A parietal pleura is closed with a recovery of the air tightness of the pleural cavity and a layered closure of dissected muscles, a fascia. Then, after the drainage is removed from the pleural cavity, and the patient is activated on the 2-3 day after a completion of the first stage, a halo-traction is performed until the second phase. The second stage involves a dorsal spinal correction using metal fixing members and pacing a graft material on the decorticated posterior elements of the spine. A seventh, or eighth, or ninth rib to be approached is resected from the thoracic approach at the top of the deformity. The resected rib is placed into a formed bed in the subcutaneous tissue and fixed to underlying tissues to be used as an autograft later. The resected rib is anchored for a period until the final stage of the dorsal correction is competed. At the stage of the dorsal correction of the spine, the resected rib is removed from the bed, cleaned of soft tissues, and after treated in the antiseptic solution, placed on the decorticated posterior elements of the spine. At the final stage of the dorsal correction, a portion of the rib is placed in the form of milled auto-chips of the decorticated elements. While performing the final dorsal correction of the spine, the fixing elements made of titanium or its alloys are used.

EFFECT: method protects reliably the dural sac and its contents from the injury, provides preparing the full posterior fusion with the repaired configuration of the spinal canal.
