Nerve Magnified Regeneration by Distal Nerve Transfer in High Ulnar Nerve Injury

The concept of nerve-magnified regeneration, part of which is end-to-side nerve transfer, provides a theoretical basis for the treatment of high ulnar nerve injuries. High injury to the ulnar nerve causes severe consequences, such as loss of sensation, loss of movement and “claw hand” deformity, affecting the fine motor skills of the hand. A method of nerve-magnified regeneration – distal nerve transfer – interosseous anterior (median nerve) to the deep ulnar nerve at the wrist level is presented, used in 20 patients (2 to 66 years of age) with an average follow-up period of 3 years (10 months to 5 years). This is a microsurgical method for rapid re-innervation of the most distal hand muscles in proximal neurotmesis of ulnar nerve.
