[Vascular bed of the fingers in injuries of flexor tendons and arteries].
Active movements of 161 fingers after a tendon suture in the "critical" area have been examined in 36 +/- 1.4 months after injuries. Impairments of the vasculo-neural fascicles have been detected in 61.2% of fingers whose movements did not differ from the movements of the fingers with intact innervation and circulation. Contrast arteriography (in cadaver experiments) of cut wounds of the fingers with disruptions of the tendons and arteries has shown that disruption of both the main arteries with crossing the soft tissues of the palmar and lateral surfaces of 2-5 fingers excludes the arteries distal to the injury from the blood flow. Intact soft tissues could provide the functioning of the collaterals along approximately 10 mm on the proximal phalanx and 6 mm on the middle one. After tendon sutures the tendons regeneration takes place in conditions of intact collateral circulation in cases with wounds of 2-5 fingers, involving injury to one artery, or of the main arteries of 1 finger, or with intact soft tissues on the palm surface of 2-5 fingers.
