[Alloplasty in combination with internal osteosynthesis in the treatment of partial defects of articular ends of the tibia].

In the article are presented the modern possibilities of surgical treatment of posttraumatic inveterate defects of articular ends of tibia on the basis of alloplasty and perosseous osteosynthesis application. There are described indications for operation, its, peculiarities due to accompanying injuries, methods of postoperative rehabilitation, complications. There has been stated that the application of perosseous apparatus, allowing for early joint functioning, ensures reduction of the patient treatment terms by 2 times under the conditions of unloading of the osteochondrous allotransplant.

[X-ray diagnosis of aseptic necrosis of the femur head in adults at the preclinical stage].

The time course of an x-ray picture from the normal bone structure up to the appearance of positive x-ray signs of aseptic necrosis of the head of the femur (ANHF) was followed-up. The former, appearing long before the development of clinical signs of disease, were foci of the rarefaction of a round or oval shape in the upper, central parts of the head of the femur, and along its periphery in somewhat dense or normal structure of the head of the femur.

[Early diagnosis of aseptic necrosis of the femur head in adults].

Having analysed the case histories of 121 patients with unilateral aseptic necrosis of the femoral head the authors revealed early roentgenologic symptoms of aseptic necrosis in the other hip which was normal on admission in 19 patients with absence of the clinical signs of the disease. In other 13 patients at different terms after the exposure of the roentgenologic changes (up to 9 years) a clinical picture of aseptic necrosis of this previously normal joint developed. A picture that is characteristic both of the preclinical stage and of other stages of aseptic necrosis of the femoral head may be revealed in the roentgenograms during the initial examination of the patient, which is connected with some peculiarities of the course of the disease.
