METHOD OF ANTERIOR SPONDYLODESIS IN CASE OF NON-SPECIFIC SPINE SPONDYLODISCITIS (VERSIONS) Russian patent published in 2013 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to vertebrology. Intervertebral discs are ablated, adjacent with disc parts of neighbouring vertebra are resected via anterior mini-access. Step-like cavities with rectangular slot from anterior side of spine are formed in vertebrae bodies with partial preservation of lateral masses of vertebrae bodies and preservation of periosteum of posterior edge of vertebra body. Slot height and depth constitute Ѕ of height and depth of vertebra. T-shaped transplant with rectangular dorsal projection in the central part is formed from iliac bone and installed into inter-body space in such a way that its base enters slots in vertebrae bodies with its ends and cranial and caudal edges of protrusion contact respective surfaces of resected neighbouring vertebra. In accordance with the second version method includes paraumbilical mini-access from the left with indent from navel - for L4-L5 segment, or paraumbilical access from the left with indent from navel to the left and downward for L5-S1 segment. After that, intermuscular access with preservation of vasculo-nervous bundles is performed by means of retroperitoneoscope. Peritoneum is separated medially to anterior surface of operated vertebrae bodies. In zone of operation cavity is formed, after which mobilisation of ureter vessels and ligation of segmental vessels at the level of target intervertebral disc are carried out. Anterior longitudinal ligament is excised, paravertebral abscesses are opened and intervertebral disc is ablated. Bed preparation and transplant insertion are performed as in the first version.

EFFECT: method makes it possible to reduce treatment terms and risk of development of post-operative complications.
