[Intravenous spondylo-infusion in the treatment of lumbar osteochondrosis].

Using the intraosseous infusion technique, 87 patients with neurological symptoms of osteochondritis of lumbosacral intervertebral disks (study group) were treated. Sixty-six patients were treated by traditional drugs (control group). The study and control groups have been matched by age (mean 45 years) and symptoms--reflex-muscular, spondilosis radicular, Charcot's syndrome. An estimation of treatment efficiency was carried out by registration of somatosensory evoked potentials and ultrasonic dopplerography of the inferior vein cava and its branches as well as by measuring of intraosseous pressure in an acantha before and after infusion of a solution. The diskogenic neurological frustrations regressed more promptly and completely in the patients, to whom the intraosseous infusion technique has been applied. The positive correlation between clinical recovery and a decrease of a latency of somatosensory evoked potentials peaks is revealed. The intraosseous pressure in an acantha after a course intraosseous infusion was reduced. The directions for applying intraosseous infusion technique are developed.

[Microbial flora in spinal hematogenous osteomyelitis].

The analysis of microbic flora of the pus and granulations of 155 patients, operated on hematogenic osteomyelitis of vertebral column. The microbic agents were detected in 81.2% of the patients in subacute stage of the disease, in 48.5% of the patients with chronic stage and duration of the disease less than one year, and in 74.3% of the patients with the duration of the disease exceeding one year. In all cases monoculture was detected with the domination of Staphilococcus (69.2%-83.0%). A comparative analyses of the rate of penetration of the infective agents into the spongeous bone of a damaged vertebra. In case of resection of one third of the height of a vertebra the frequency of detection of an infective agent in subacute stage of a disease decreases 2 times, and in chronic stage-in 4 times. These data provides an opportunity of verification of indications for the surgery.

[Immunological studies and the problems of the pathogenesis of osteoarticular tuberculosis (tuberculous spondylitis, tuberculous synovitis)].

Tests of levels 1-2 were employed to study immune status of 102 patients with tuberculous lesions of the spine and knee joint. Investigations of humoral local response in these patients provided evidence for comparison with systemic response, advanced diagnosis of tuberculous spondylitis and synovitis. It was found that high level of antituberculous antibodies in the synovial fluid is typical for specific allergic synovitis where synovial membrane represents the organ of immunogenesis. The appearance of even minimal number of antituberculous antibodies in the liquor indicates disorder of immune and hematoencephalic barriers of the brain in tuberculous spondylitis complicated with spinal meningitis.

[Indicators of systemic and local immunity in patients with spinal tuberculosis].

The examination of 33 patients with tuberculous spondylitis and its sequelae revealed inhibition of T-cell immunity in 40% of the examinees, antituberculous antibodies in the blood of 73% of patients. An enzyme immunoassay detected antituberculous antibodies in cerebrospinal fluid of 70% seropositive sufferers with spinal tuberculosis. Positive results of this test serve a direct indication to spinal decompression and intensive pre- and postoperative antituberculosis treatment.

[Pathologic changes in vertebral osteomyelitis].

Osteomyelitis of the vertebral column (VC) was considered in the past as a form of sepsis. The disease developed after purulent infection provoked by staphylococcus, enterobacteria and other infectious agents, rapidly progressed and terminated not infrequently, by a patient death. Wide spread destructive process due to the purulent lysis of the bone and cartilage was observed in VC. This disease acquired some new features at present. Although its etiology remained the same, osteomyelitis of VC is now chronic inflammatory process with recurrences and formation of purulent foci in VC with the spread to the paravertebral tissues and adjacent organs. The number of grave complications is reduced and lethal cases are practically absent.

[Osteoplasty in limited forms of tubercular spondylitis].

The developed variants of free and non-free vertebral autoplasty are considered to be optimal in the surgical management of tuberculous spondylitis. Their application is associated with the damage to vertebral bodies, the degree of their destruction, the extent of intervertebral diastasis, and the process site. Proper repair of the vertebral defects, not exceeding 5 cm, is achieved by free autografts having the maximum area of supporting ends. With extensive intervertebral diastasis, it is recommended to use non-free grafts taken from a rib or the upper flaring portion of the ilium and to overlap the plasty area with the rib periosteum on a feeding pedicle. In terms of significance order, the prognostic criteria for plasty outcomes are congruence of the graft ends with the grooves formed in the vertebral bodies; the extension of a suppurative process in the adjoining transplant tissues, adequate correction of intervertebral diastasis; and the length of transplants.

[Tactics in surgical treatment of combined and complicated forms of active tuberculosis of the spine and lung].

Questions related to surgical treatment of combined forms of active spinal and pulmonary tuberculosis are discussed. The results of conservative and surgical treatment of 14 patients with this pathology were analysed. Tactics of treatment of such patients was established. It was shown that emergency surgery on the spine because of the developing complications can be performed together with intensive antituberculous therapy.

[Surgical treatment of hematogenic osteomyelitis of the spine].

The article presents principles of the surgical treatment of hematogenic osteomyelitis of the vertebral column and its complications developed on the basis of studying and analysis of results of operative interventions performed in 145 patients. A system of operative procedures is proposed which showed high effectiveness in treatment of both purulent infections and complications of the disease, spinal disorders in particular.
