Sciatic nerve morphological study for experimental treatment of combined pelvis and femur injury using transosseous osteosynthesis method

Abstract

The work deals with the results of morphological sciatic nerve study experimentally in 10 dogs with modeling a combined injury of pelvis and femur and its treatment by transosseous osteosynthesis method. The closed injury of sciatic nerve has been revealed with neurapraxia and axonotmesis: the damage of nerve fiber myelin sheathes and axons with further Wallerian degeneration without nerve sheath involvement. The recovery of sciatic nerve morphological structure was of incomplete character by 6 months after device removal (215 days).
