[Vascular disturbances in craniovertebral pathology in children and adolescents].

The peculiarities of craniovertebral abnormalities and dysplasias in children and adolescents have been studied. Different diagnostic methods (dopplerography of spinal arteries, ultrasonography, remote infrared thermography, laser doppler flowmetry, etc) were compared. The outlines for treatment the patients with cervical dysplasias are described.

[Atlanto-axial instability in injuries of the ligament system in children and adolescents].

There has been carried out an experiment with 6 craniovertebral blocks with contrasting of the vertebral arteries and studying of the influence of different damages of ligamentous apparatus on blood flow in vertebral arteries. In all cases there has been discovered significant vertebrogenic influence. Experimental data have been corroborated with clinical material. There have been examined 31 patient with different damages of ligamentous apparatus of craniovertebral segment, with 21 of them has been detected significant vertebrogenic influence at ultrasound dopplerography of vertebral arteries.

[Clinical aspects, diagnosis and surgical treatment of developmental anomalies of the cervical spine].

The examination of 20 patients with abnormal cervical spine has identified Klippel-Feil disease in 12 of them, isolated vertebral synostoses of the cervical spine in 8. In 2 patients with Klippel-Feil anomaly neurovascular syndrome was reported which resulted from compression of the neurovascular bundle by extra cervical ribs. Indications to surgical treatment in Klippel-Feil disease are specified. The authors performed operations to correct the cosmetic defect and relieve compression of the neurovascular bundle in neurovascular syndrome.

[The pathogenesis of elevated intracranial pressure in children and adolescents with craniovertebral pathology].

The paper deals with intracranial hypertension in children and adolescents. Thirty-six patients with the upper cervical dysplasia and identified associated intracranial hypertension were examined. Magnetic resonance imaging and functional tests were used. Some patients were diagnosed as having a thickened ligamentous apparatus at the level of craniovertebral junction, which was a cause of spinal fluid dynamic disorders and led to elevated intracranial pressure.

[Halo-traction efficacy in surgery on the cervical spine].

The paper deals with the use of a halo-apparatus in lesions and diseases of the cervical vertebra. The halo-apparatus was used in 70 patients. It was most commonly employed in lesions of the upper cervical vertebra, such as fractures of the odontoid process and C2 vertebral arches. Analyzing the clinical findings showed halo-traction to be highly effective.

[Diagnosis and treatment of paretic forms of lumbar osteochondrosis].

This study was based on the analysis of the results of examination and treatment of 85 patients with lumbar osteochondrosis with paretic disturbances. The degrees of neurological disorders were analyzed by distributing these patients into three groups including patients with monoradicular, polyradicular motor disorders and circulatory disturbances in the caudal portions of the spinal cord. The informative value of the performed techniques (X-ray study, MRI, myelography, myelography with computed tomography, electroneuromyography) and the necessity of their combination for increasing the quality of diagnosis were determined. Criteria for choosing this or that treatment were defined. Indications for surgery, the time of its performance, and its efficiency were investigated. Surgical outcomes were analyzed by the groups of patients. The paper shows it necessary to use metallic fixing devices in some cases in order to stabilize an altered segment degeneratively, which allows improve the outcome of a surgical intervention. Postoperative rehabilitative treatment is also outlined.

[Tactics of surgical treatment for an inflammatory process of C0-C(I)-C(II) segments in the craniovertebral joint instability].

Pathological processes of C0-C(I)-C(II) segments, such as the clivus, atlas arch, dens, and body of the C, vertebra pose major problems for diagnosis and treatment. On removal of a sizable pathological focus, there may be instability of the craniovertebral segment, secondary displacement, and spinal compression syndrome. Therefore these patients frequently need stabilization of the craniovertebral transition. Patients with initial instability of the craniovertebral junction and subluxation of C(I)-C(II) segments are an intricate problem. The authors describe a rare case of an inflammatory process of C0-C(I)-C(II) segments with craniovertebtal junction instability. A differential diagnosis was made between chordoma, osteoblastoma, and an inflammatory focus at the above site. The following tactics was undertaken: the first stage was occipitospondylosynthesis with "Vertex" system with osteoplasty under Halo-traction; the second stage included transoral removal of a pathological removal of the dens and body of the C(II) vertebra, left lateral mass of the CI vertebra, and lower clivus. After removal of the pathological focus, there were portions of the abnormally changed bone with rarefaction without tumor tissue. Histologic studies revealed the signs of a chronic inflammatory process. A five-month follow-up showed that neurological symptoms and craniovertebral junction instability regressed. The control computed tomography made 5 months after surgery demonstrated the radical elimination of the pathology and the absence of C, vertebral subluxation. Thus, there is evidence for the tactics of successive operations (a stabilizing operation--posterior occipitospondylosynthesis (desirably under Halo-traction), followed by removal of a pathological focus via transoral access) in pathological processes of the craniovertebral C0-C(I)-C(II) in cases of initial craniovertebral junction instability.
