Degenerative diseases of the lumbar spine against a background of osteoporosis are frequently accompanied by pain, neurological disorders, disorders of the pelvic organs, changes in the locomotor function of the spine affecting the quality of life of the patients. Surgery for this pathology uses various devices for introduction of the bone cement, which have both advantages and disadvantages. The authors analyze the results of surgical treatment of the patients with various types of spine pathology (degenerative lumbar scoliosis, spondylolistesis, spinal canal stenosis, uncomplicated compression fractures of the vertebral bodies against osteoporosis and aggressive hemangiomas using a universal device for introduction of bone cement and cannulated screws produced by Vostok−N (Kharkiv). In spite of a small instrument kit, this device allows to perform two types of surgical operations: transpedicular stabilization and vertebroplasty both separately and in combination. The use of cannulated screws with bone cement in diseases of the spine against a background of osteoporosis promoted stabilizing tranpedicular constructions, prevented resorption zones development near the screws and created favorable conditions for spondylodesis. The state of the patients was assessed 3, 6, 9 months after the surgery using visual analog scale and Oswestry index of stabilization. Positive dynamics of the neurological state (regression of the pain syndrome, transitory neurological deficiency, disappearing of sensitive and reflectory disorders) was observed.
