[Calculation of the main parameters of spokes for intramedullary reinforcement of tubular bones].

The goal of this work was to determine the optimal geometric parameters of plastically deformed spokes inserted into the medullary canal during intramedullary reinforcement performed as a part of perosseous distraction osteosynthesis. The results of clinical application of the suggested technique are described.

[Biomechanical analysis of the load on the intercondylar surface of the knee joint in frontal projection].

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.

[A method for determining the impulsive force range in experimental simulation of various long bone fractures].

The dependence of the bone fracture characteristics on the impulsive force parameters was studied. An original method for quantitative assessment of the traumatic impulsive force was suggested. Preliminary experimental studies in osseous specimens from dogs revealed the range of the impulsive force parameters to be used in experimental simulation of long bone fractures.

[Use of hinge joints in devices for treatment of human locomotor system].

An analytical review of hinge joints used in external osteosynthesis apparatuses is presented. The goal of this review was to help to optimize the construction of new external osteosynthesis apparatuses based on hinge joints and to improve the procedure of their installation. Several variants of hinge joint construction are considered. The review points out the specific properties of these joints that have to be taken into account in development of medical equipment.
