ABSTRACT

The articular cartilage was studied under conditions of experimental osteoarthrosis with tunnelization of the subchondral zone and injection of autologous bone marrow into the channels. Histomorphological studies showed that tunnelization of the subchondral zone with injection of autologous bone marrow into the channels stimulated reparative regeneration of the chondral tissue by inhibiting destruction of the joints.

ABSTRACT

The article is intended for experts on biomechanics, traumatologists, and orthopedists working in the field of the large joint pathology treatment. The method for analysis of the load on the knee joint presented in this article makes it possible to predict development of local necrosis of the joint surface caused by abnormal biomechanical axis of the lower extremity. The method also allows the necrosis center location to be determined with sufficient accuracy. Besides, the article provides a theoretical basis for preoperative design in the case of operative correction of the biomechanical axis of the leg intended to optimize the intense-deformed condition of the knee joint.

ABSTRACT

Roentgenoradiological control of a reparative process after diaphysial comminuted shoulder fractures was exercised at all stages of the treatment after G. A. Ilizarov's method. Osteoscanning permitted the assessment of the viability of bone splinters on the first days after trauma and quantitative assessment of the activity of osteogenesis. A study of the optical density of radiograms provided an opportunity for evaluation of mineral content in regenerating bones, their structure only at late stages of treatment when it was rather high.
