Reflex excitability of spinal centers of hand muscles was examined in normal subjects and patients with traumatic lesion of forearm nerves. Central and peripheral muscle responses were evoked by stimulation of homonymous and heteronymous nerves. Patients with median and/or ulnar nerve lesion showed the heteronymous abductor pollicis brevis and abductor digit minimi H-responses. The cause of appearance of heteronymous responses is supposed to be actualization of latent heteronymous monosynaptic connections following traumatic lesion and afferent deprivation. It seems obvious that activation of heteronymous pathways corresponds to the process in afferent system known as "revitalization" of median-to-ulnar anastomoses after damage.

The authors analyse their clinical experience of treating 5 patients with immobilization of the hand and propose to use complex and composite vascularized grafts for the plasty of extensive defects of tendons and skin of the forearm. They consider microvascular grafting of skin flaps from the back of the foot with tendons from the extensors of the toes with their own paratenon to be an excellent material for the reconstruction of the tendons of the flexors. They advise to use the vascularized broad fascia of the hip incorporated into the lateral flap from the hip for the plasty of extensive defects of the tendons of the extensors. The authors point out that the indications for using a combined graft from the back of the foot carrying vascularized tendons require further elaboration.
