[The specific features of surgical spinal stabilization in children with tuberculous spondylitis complicated by severe kyphosis].

Procedures for anterior spine fusion and posterior instrumental spinal fixation have been developed for the surgical treatment of childhood tuberculous spondylitis complicated by severe kyphotic deformity. The optimum method of the instrumental fixation is the use of multisupport constructions with the heterodirectional action of corrective efforts (in 15 children). Anterior osteoplastic stabilization of the vertebral column, by applying brace cortical grafts with saddle-shaped hollows on the tips of its ventral projection, was applied in 6 children. A significant and steady-state correction of kyphosis was achieved in all the cases; there were no complications of anterior spine fusion and posterior instrumental fixation.

[Clinical classification of extrapulmonary tuberculosis].

The authors propose a clinical classification of extrapulmonary tuberculosis, which is based on the standard reporting signs. They give the definitions of classification criteria established in any locations of tuberculous infection: etiology (tuberculosis, BCG infection, tuberculoallergic lesions), the extent and activity of a process with regard to clinical and morphological stages; bacterial isolation with consideration of the drug resistance of Mycobacteria; the nature of complications and sequels, etc. The characterization of local lesion includes the determination of organ-dependent clinical forms of tuberculosis; the type and form of complication; residual and sequels.

[Osteoarticular tuberculosis in children: data extrapolation of a specialized clinic to the situation in the Russian Federation].

Analyzing the activities of the Surgery Department for Osteoarticular Tuberculosis (OAT), Saint Petersburg Research Institute of Phthisiopulmonology, in children in 1990-2002 suggests that there is no system for comprehensive registration of OAT and in most cases its treatment is performed without taking into account the current surgical requirements. New organizational, methodological, therapeutic approaches recommended to ascertain the true OAT situation in children and to improve the results of its diagnosis and treatment, are presented.

[BCG osteitis in children (algorithms of diagnosis and treatment)].

In 156 children with osseous complications due BCG vaccination, the clinical features of disease, radiation and laboratory changes were studied. An algorithm of diagnosis of BCG ostitis and a system of organizational measures whose implementation make it possible to objective the statistical registration of BGC ostitis in Russia are proposed.

[Tuberculosis of respiratory organs concomitant with tuberculosis of bones and joints in young children].

Specific features of thoracic tuberculosis were studied in children with various forms of tuberculosis of bones and joints, i.e. tuberculous spondylitis, arthritis and osteitis. Peculiarities of the clinical course and of complications of thoracic tuberculosis were detected in children with the mentioned clinical forms, which are mostly pronounced in spinal tuberculosis and tuberculosis of joints. A complicated course of thoracic process predetermines the duration of treatment and affects the choice of time for surgical intervention.

[Instrumental correction of severe kyphosis in tuberculous spondylitis in young children (new technology)].

A new mode has been proposed to correct deformities in tuberculous spondylitis complicated by more than 50 degrees kyphotic deformity. The mode involves extended repair of the vertebral column, supplemented by the use of Luque-modified posterior multisupport hooked contractors. The mode ensures correction deformity to 47 degrees. The procedures of a surgical intervention are described.

Neurological complications of spinal tuberculosis in children.

Neurological complications of thoracic and lumbar spinal tuberculosis were studied in 32 patients under the age of 16 years. The majority had lesions involving three or more vertebral bodies. Paraplegia occurred in 8 patients and was always associated with bladder and bowel dysfunction. Lesions located at T4/5 were most commonly accompanied by paraplegia. Deterioration of the neurological status was related to the degree of spinal stenosis, whereas the degree of kyphosis was of less importance. Radiculopathy is rare in children with Pott's disease.

[Correction of kyphosis in tuberculous spondylitis in children].

Various modifications of radical reparative surgery were made in 145 children with tuberculous spondylitis were comparatively analyzed. Greatest correction of kyphosis was achieved by combining anterior spinal repair with posterior plunged contractors, in additional resection of the apical vertebral arch in particular. There is a direct correlation between the degree of compression of the dural sac and the severity of neurological disorders. Anterior decompression of the spinal cord is an obligatory surgical component in tuberculous spondylitis, eliminates central stenosis of the spinal canal; however, it is insufficient to eliminate neurological disorders caused by myelic ischemia.

[Stepwise motor rehabilitation of children with neurologic complications of tuberculous spondylitis].

The proposed protocol for postoperative motor rehabilitation of children with tuberculous spondylitis complicated by severe neurological disorders is based on the procedures developed by the authors to induce spinal locomotor activity. The developed algorithm of motor rehabilitation of spinal patients involves separate restoration of gait components (rhythmic stereotypic walking (spinal locomotion), maintenance of a standing posture and voluntary control over the movements ensuring gait. The stages of motor rehabilitation were defined by taking into account these factors and a child's neurological status. The use of the algorithm in the treatment of 11 children with tuberculosis and 13 children with other spinal diseases resulted in the restoration of normal compensatory gait or in its formation in the vast majority of patients.

[Treatment policy for children with complicated osteoarticular tuberculosis].

Experience in treating 97 children aged 1 to 14 years who had complicated tuberculosis of the spine (n = 74) and large joints (n = 23) in a specialized surgical clinical setting is presented. The developed treatment policy involves early radical reparative or reconstructive surgical intervention and intensive long-term therapy. The treatment allows one to cure 96.3% of children, yielding good functional results in 82.5% of them.

[Tuberculous osteitis in infants].

Clinical and diagnostic aspects, surgical outcomes, bacteriological findings were investigated for 72 infants under 3 years old operated for tuberculous ostitis. Tuberculin and seroimmunodiagnosis revealed infection allergy in 1/3 of the cases. The treatment comprises radical surgical reconstruction, drug and functional therapy. Tuberculous ostitis may arise due to vaccinal strain of M. tuberculosis.

[Current achievements in surgery of osteoarticular tuberculosis in children].

The paper covers the past 10 years' experience in the surgical treatment of children with various osteoarticular tuberculosis types. A total of 456 children aged 10 months to 16 years were studied. The author used a system of radical corrective and reconstructive osteoplastic operations in restrictive and disseminated diseases, which had been developed with regards for age-specific features of the abnormality. In addition to radical removal of inflammatory foci, the system provides for obligatory restoration of reconstruction of the diseased joint or spine, which has a favourable influence on the further development of a child's skeleton. Successful therapy and good functional results were achieved in 100% of children with focal bone lesions, in 98.5% of those with tuberculous spondylitis, and in 84.6% with large joint tuberculosis.

[Magnetic resonance tomography in the diagnosis of tuberculous spondylitis in children].

The experience of using magnetic++-resonance tomography to diagnose tuberculous spondylitis in 15 children admitted to a hospital for surgical treatment is described. The method proved to be highly effective for evaluating the condition of the spine and spinal medulla and for establishment of early diagnosis of the attendant neurotrophic changes in healthy vertebrae. The examination findings serve to determine the volume of surgical intervention, character of postoperative restorative management and allow the prognosis of treatment outcome. In this respect, magnetic++-resonance tomography is a valuable supplementary diagnostic method.
