spinal fixation in spondylolisthesis, reducing the height of the intervertebral disc - fusion bone allograft or autografts - it neurosurgical operations carried out to create a stillness between adjacent vertebrae after failure of conservative treatment of degenerative intervertebral disc disease, instability of the spinal segment, spinal deformities, spondylolisthesis.

Intervertebral disc serves as a "depreciation" movements.At its removal violated biomechanics of the spine, there is the risk of instability and pain.If the mobility in the segment more than the permissible value by 5 - 7% - this segment is unstable and could provoke infringement of nerve and muscle structures, increase the pressure on the joints, leading to degeneration and Osteoarthritis - pain syndrome. Spondylolisthesis - ¬ęslippage" body displacement of the overlying vertebra.

Spinal fusion

Spinal fusion stabilizes the vertebrae and discs by creating connections - fusion of adjacent vertebrae.This excludes any movement bet

ween the fixed vertebrae.When fusion at one segment of the patient does not feel limited mobility.
developed different techniques and methods of surgical techniques such operations at different levels of the spine.
Preparation for surgery - the standard - General clinical tests, physical examination, X-ray examination of the spine - rentgennogrammy with functional tests, computer and magnetic resonance tomography, discography.
Posterior spinal fusion is performed under spinal deformity - scoliosis, kyphosis, spondylolisthesis.

Keiji PEEK-ceramics for the thoracic and lumbar spine

transforaminal lumbar interkorporalny spinal fusion is performed through a posterior approach, in the vertebrae screwed special screws, performed removal of the intervertebral disc, is introduced in its place a spacer to the implant (possiblytaken from a patient's pelvic bone), further into the side grooves of the vertebral bone implants are installed.Fasten the screws to the terminals and the wound sutured.Over time, the bone implant "take root" and there is fusion of the vertebrae - still fusion.

Hospital stay - individually - 3-5 days.Later korsetirovanie recommended load limit, rehabilitation - an average of 6 weeks.

For operations in degenerative changes of intervertebral discs in combination with spondylolisthesis at the levels of the lumbar - L2-S1, with long-term pain and inefficiency of conservative therapy is possible to use the implant B-Twin.This operation can be performed by open - through the front or rear access or through the posterolateral access percutaneously.

As a result of examination the doctor chooses the method of operation and access selected implant size.Held discectomy, intervertebral space to set the implant in the folded and moved apart.

Contraindications to the use of the implant is quite extensive and the possibility of its application solves neurosurgeon.Metabolic bone disease, neurofibromatosis, osteoporosis, tuberculosis, immunodeficiency, malignancies - not the whole list of contraindications.The doctor must be notified of an illness prior to treatment (for any reason), the duration of reception of hormones, calcitonin, vitamin D ... available drug allergies and allergies to metals.

Complications - Complications of anesthesia - allergic reactions, nerve damage structures, infectious complications, neudovletaoritelnoe fusion of the vertebrae, the need for re-operation, continuing pain.

Reconstructive Vertex Select system is used during operations on the cervical spine for fixation of the vertebrae and the occipital bone.

alternative to fixed fusion of vertebral bodies developed technique of artificial intervertebral disc.When such an operation is restored movement between the vertebrae.The operation is performed via transabdominal access the contents of the abdominal cavity is moved to the side, remove the affected disc, instead set two plates and between the plastic "backup", which ensures the mobility of the vertebrae.

intradiscal electrothermal therapy (IDET) - This disc electrocautery method, to strengthen it, "stitching".The damaged disc catheter with an electrode, electric current is applied.

operative treatment achieved a stable fixation of the spine structures, decompression of neural structures, restoration of spinal biomechanics, prevention of irreversible changes in the affected segment, early activation, shortening of terms of hospitalization and rehabilitation.
