METHOD FOR TWO-STAGE SURGICAL MANAGEMENT OF SPINAL DEFORMITY WITH USE OF RESECTED AUTOREB PRESERVATION Russian patent published in 2024 - IPC A61B17/70 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgery and vertebrology. And can be used for two-stage surgical treatment of spinal deformity using preservation of resected auto rib. At the first stage, a ventral release is performed at the apex of the deformation from the thoracotomic approach with a subperiosteal separation of the rib and a resection of its part to be placed in the formed bed-pocket in the subcutaneous tissue and performing its fixation to underlying tissues for subsequent use as an autograft. Discectomy and resection of end plates are followed by filling interbody spaces with a haemostatic sponge. Parietal pleura is closed with restoration of pleural cavity tightness and layer-by-layer closure of dissected muscles and fascia. After the first stage of the surgical intervention, the halotraction is performed until the beginning of the second stage of the surgical intervention, dorsal spinal correction. At the second stage, dorsal correction of the spine is performed using metal fixing elements and with placement of the autograft material on the decorticated posterior elements of the operated spine. In the process of performing the ventral release from the thoracotomic approach, the seventh, or eighth, or ninth rib is resected at the apex of the deformation, along which an access is performed in the form of an autograft with length of 10–15 cm, then after performing discectomy and resection of end plates with subsequent filling of interbody spaces with haemostatic sponge, closure of parietal pleura with restoration of pleural cavity tightness and by layer-by-layer closure of the dissected muscles and fascia, the resected autograft rib is placed into the disinfection kit. Resected autograft rib is preserved. At the stage of dorsal spinal correction, the resected autograft rib is removed from the disinfection kit, which is a sealed container, and after treatment in an antiseptic solution is placed on the decorticated posterior elements of the operated spine.

EFFECT: method provides obtaining a complete posterior bone block, reliable biointegration and absence of antigenic properties and infectious complications due to performance and features of conservation.
