Posterior spondylodesis method for treating vertebral column injuries and disease cases

FIELD: medicine.

SUBSTANCE: method involves exposing spinous processes over arcuation arch, cutting them near the base and turning aside together with soft tissues. Distortion being corrected, bone bed is formed on vertebral arches with cortical layer being removed on convex side. The spinous processes are laid on the prepared bone bed so that one process overlaps two adjacent vertebrae.

EFFECT: high vertebral column stability under maximum possible correction condition.

The invention relates to medicine, namely to traumatology and orthopedics.

There is a method of surgical treatment of scoliosis Halstead-Vreden (Iasconsole. Operative Orthopaedics. Moscow: Medicine, 1994, str), including rear access throughout the arc of curvature of the spine with the exposure of the spinous processes on the one hand, osteotomy them together with soft tissues turn in the other direction. Rigid autograft is placed in a formed on the bases of the spinous processes of deepening and press previously turned spinous processes.

Considered the method allows for stabilization of spinal deformity, but the use of rigid autograft entails the execution of a separate surgical intervention on the fence rigid autograft, which increases the injury and the operation as a whole.

The objective of the invention is to increase the stability of the spine at the maximum possible correction and reducing injuries and time of surgical intervention.

therapeutic result of the task is achieved by the fact that way back fusion of the spine in the treatment of scoliosis, including rear access throughout the arc of curvature of the spine with the exposure of the spinous processes with the convex side of the curvature, the PE escoude spinous processes at the base and together with the soft tissues turn concave side, after the execution of the main phase correction of the spine metal construction making the formation of the bone bed on the arches of the vertebrae with the removal of the cortical layer on the convex side of the deformity, spinous processes to turn into the prepared bone bed, so that one process overlaps the two adjacent vertebrae. Top stitched the muscle layer, pressing spinous processes to the rear sections of the vertebrae.

In the drawing 1A shows a General view of part of the spine on the apex of deformity: POS.1 - spinous process, pos.2 - transverse process, 3 - arc vertebra, pos.4 - paravertebral muscles. In the drawing 1B - stage operation (cutting off the spinous process): item 1 - spinous process. In the drawing 1B is a view of the spine on the stage of the operation: 3 - formation of the bone bed, pos.6 - designated osteotomy of the spinous process. In the drawing 1G - POS.1 - spinous processes, pos.7 - metal andconnector.

The proposed method is as follows: is the rear access throughout the arc of curvature of the spine with the exposure of the spinous processes with the convex side of the curvature, cross spinous processes at the base and together with soft tissue turns concave side, after performing the main stage of correction of the spine metal design productivity is by forming a bone bed on the arches of the vertebrae with the removal of the cortical layer on the convex side of the deformity, spinous processes are wrapped on the prepared bone bed, so that one process overlaps the two adjacent vertebrae. Top stitched the muscle layer, pressing spinous processes to the rear sections of the vertebrae.

Way back spinal fusion in the treatment of injuries and diseases of the spine, including rear access throughout the arc of curvature with the exposure of the spinous processes, their intersection at the base and together with the soft tissues turn them aside, characterized in that after the correction of the spine metal structure forming a bone bed on the arches of the vertebrae with the removal of the cortical layer on the convex side of the deformity, the spinous processes are placed on the prepared bed so that one process overlaps the two adjacent vertebrae.

SUBSTANCE: method involves making longitudinal incision in tibia projection. Pathologically changed tissues are withdrawn. Two cutaneofascioperiosteal flaps produced by separating longitudinal surgical wound edges from bone are used for filling. Threads are conducted through bone. The cutaneofascioperiosteal flap ends are sutured and drawn close with the frontal thread ends. The rear thread ends are brought to posteroexterior shank surface and fixed on support members. Filling tissues are adapted to bone wound walls by progressively increasing tension in threads conducted through bone.
