Biological osteosynthesis as the treatment mode for multifragmental extra-articular fractures of lower limb long bones.

The concept of stable-rigid osteosynthesis developed by AO ASIF was subjected to basical changes recently, with regard to the treatment strategy of multifragmental extra-articular fractures. The principle of biological osteosynthesis was worked out, which, in contrast to AO original concept, implies the indirect (closed) reduction and "bridge-like" (elastic) fixation, without intervening on fracture area, and additionally, with maximally preserved vascularization of intermediate fragments. The study objective implied the consideration and analysis of the results of biological osteosynthesis, performed on multifragmental extra-articular fractures of lower limb long tubular bones, also to determine the indications and advantages of different methods of biological osteosynthesis.
