[Experiment study of multimicrovacuolar absorbing collagenic system and its role in trophic processes of nonsynovial part of the tendons].
The arterial inflow disorder and occurrence of an acute and subsequent chronic ischemia constitutes frequent complication of a hand and fingers trauma. One of the consequences of ischemic damage of tissues is formation of a flexor contracture of fingers, involving the flexors tendons. In extrasheath zone the blood supply is secured by paratendon--a connective tissue, taking part in the tendons sliding. According to data, obtained during morphological investigation of paratendon in laboratory animals, there was established its principal similarity with multimicrovacuolar collagenic absorbing system of a man. She constitutes a spatial porous structure, packed with cellular elements and vessels. While simulation in experimental conditions of the blood flow disorders, which in physiological environment is secured by paratendon, alike in disorder of the bone-tendon and muscle-tendon pathways of blood supply, there were revealed the coarse changes in the tendon structure and pronounced adhesion of tendons with loss of their sliding capacity, what had permitted to consider the paratendon blood circulation a dominating one.
