The structure and functioning of Dynastab DK - K fixator (knee joint) and its usefullness in clinical use.

The autor describes following stages of research on external fixator Dynastab DK - K (knee joint) with in - built artificial joint enabling physiological range of movement of the knee and the use of the device in functional treatment of articular fractures of the knee. The final clinical prototype of the device was developed according to the results of the experiments with anatomical preparations of knee joints in which the trajectory of the physiological movement of the knee was stated. These observations were used to construct mechanical joint with the range of movement adequate to this of the healthy knee.

[External fixation of fractures using Dysnastab-S stabilizers for massive ankle fractures of tibial bone epiphyseal articulations ].

Massive ankle fractures lead to joint stiffness and resulting decrease in range of motion. This can be avoided by functional treatment. In cases where severe soft tissue trauma coexists with bone fractures surgical treatment is limited and external fixation is the method of choice.

[The issue of fracture healing of pathologic femoral shaft fracture in disuse osteoporosis].

The result of treatment for pathologic femoral shaft fracture in case of disuse osteoporosis is presented. The patient is 15 years old male, paraplegic since the age of 2 due to traumatic lesion of the cervical spine. Femoral fracture has been reduced operatively and fixed with 2 Rush pins.

[The structure of distracting-compressing stabilizers Dynastab DK intended for functional treatment of articular fractures].

The structure of the distracting-compressing stabilizers Dynastab DK intended for functional treatment of transarticular fractures is described. The stabilizers realize the idea of functional treatment of fractures outside the hospital bed making possible free moving around of the patient during the treatment. This has been made possible owing to building-in of a mechanical articulation imitating the physiological movement in the injured joint.

[New outlook on the problem of an anatomic barrier in the lymphatics of the laryngeal mucous membrane].

The authors describe the lymphatic net of the larynx mucosa membrane. The communications of the lymphatic vessels of the larynx and neighbouring organs are analyzed in hypertrophy and atrophy of the mucosa. The experiment performed by means of injections proved that the subglottic area is not a barrier between the two areas of laryngeal mucosa lymphatic system.
