Using a complex of ultrasonic methods, vertebral basilar system hemodynamics has been evaluated in normal state and in case of vertebral basilar insufficiency (VBI). The differential diagnostic criteria of atherosclerotic and vertebrogenic types of VBI development have been obtained that enables to individualize the therapeutic approaches.
A case of a rare combination of two congenital diseases--multiple exostotic chondrodysplasia and Wolf-Parkinson-White syndrome--is reported. The disease ran with episodes of cardiac fibrillation. The patient died suddenly.
The purpose of this study was to reveal the relationship between temporomandibular joint (TMJ) dysfunction and dysplasia of connective tissue (DCT). This investigation included 53 (34 female and 19 male) patients with TMJ internal derangement (ID) and 53 controls; 24 patients with marked and 53 patients with mild dysfunction of this joint. The symptoms of DCT (such as scoliosis, general joint hypermorbility) and TMJ ID were revealed. Results of this study prove that DCT is one of etiological factors of TMJ ID. The relationship between type of ID and severity of DCT was revealed.

Experiments on rabbits compared the X-ray, morphological, and magnetic resonance imaging of compression fractures of the vertebral body. Edema of the bone marrow of the vertebral body was ascertained to be a basic morphological substrate that evokes a modified MR signal. The data on 178 children with suspected compression fracture of the vertebral body were used to consider the potentialities of MRI and X-ray study in this pathology. The MRI semiotics of uncomplicated compression fractures of vertebral bodies is presented. The sensitivities of MRI and spondylography in the diagnosis of compression fractures of vertebral bodies were 100 and 62.5%, respectively.
On the basis of the results of clinicoroentgenological and tensographic investigations of 119 patients after traumas of the crural bones and ankle joint (2-36 yrs. ago) the authors showed the importance of roentgenofunctional investigation of the ankle joint, a patient being in a standing position with maximum flexion and extension of the foot. A specially designed footing was proposed. Of 77 patients after intra-articular fractures of the ankle bones various disorders in articular proportions, undetectable on routine roentgenography, were diagnosed in 29 by functional roentgenography. Articular changes on roentgenofunctional investigation were revealed in one patient only out of 42 patients with extra-articular fractures of the crural bones. Tensography showed disorders of foot biomechanics in all patients with subluxations in the ankle.

Described in the paper is the podographic unit for measuring a foot eversion angle and time- and phase-dependent parameters of foot swing and stance. It may be useful in examinations of sportsmen and young people, in mass population screening for detection of gait defects and their correction, in the course of diagnostic orthopedic studies of the lower limbs.
