Overview

• Early neurorrhaphy of acute nerve injuries provides the best outcome [1].
• Distal motor nerve transfers should be considered to preserve hand intrinsic motor function when nerve injuries occur at or above the proximal forearm [1].
• Nerve transfer is favored over nerve grafting in managing high ulnar nerve injuries because of better improvement of motor power and better restoration of grip functions of the hand [5].
• In lower-type injuries of the brachial plexus, transfer of median nerve branches that innervate the palm of the hand to the ulnar proper digital nerve of the little finger predictably restored protective sensation on the ulnar side of the hand [6].
• End-to-side distal anterior interosseous nerve transfer provides significantly better results than a standard more proximal nerve repair in the treatment of proximal ulnar nerve injuries [12].
• Vascularized ulnar nerve grafts should be recommended for reconstruction of the median or radial nerves in selected cases involving large defects after severe trauma of the upper extremity [14].
• High median nerve injuries result in absent thumb and index finger flexion and pulp anesthesia, which do not benefit from nerve grafting but are amenable to nerve transfers [25].
• Tendon transfers remain the primary reconstructive procedure for paralytic injuries of the upper limb until sufficiently powered studies of nerve transfer outcomes are published [36].
• Experimental studies and positive reports from large clinical series suggest that new techniques using foreign nerves for reinnervation are worthy of integration into the management of upper brachial plexus injuries, though many questions regarding timing, donor morbidity, and comparative efficacy remain unanswered [11].
• Clinically, nerve transfer to the median nerve using parts of the ulnar and radial nerves may offer an alternative option for proximal nerve injuries or for free functioning muscle transplantations [16].
• The biomechanical principles, indications and limitations of tendon transfers, nerve transfers and combined approaches are compared, with particular attention to timing, patient selection, and functional goals [3].

Anatomy & Pathophysiology

• High median nerve transection results in a specific clinical presentation of hand function [2].
• Biomechanical principles, indications, and limitations of tendon transfers, nerve transfers, and combined approaches depend on timing, patient selection, and functional goals [3].
• Ballistic injuries to the hand are frequently associated with fractures and neurovascular and tendon injuries [4].
• Upper extremity peripheral nerve injuries involve the median, radial, and ulnar nerves [8].
• A nerve transfer for restoration of ulnar finger flexion through the pronator teres motor branch can be suggested in cases where the hand is partially involved to allow patients to regain or strengthen finger flexion [9].
• Functional prehension requires a stable wrist and at least two sensate digits that can oppose with some power [10].
• Severe hand injuries from sword assaults can cause devastating loss of function [15].
• In combined proximal median and ulnar nerve injuries, restoring ulnar intrinsic function is critical to avoid blunt traditional anticlaw procedures, even if it requires some sacrifice of thumb motors [23].
• Opposition transfers do not require large amounts of strength to achieve thumb positioning; the mechanics and vector of pull are of paramount importance [28].
• An ulnar nerve to musculocutaneous nerve transfer in an ulnar ray-deficient infant with brachial plexus birth palsy resulted in active elbow flexion to 90° at 18 months without motor deficits in the hand [30].
• Opposition is a preparatory position for grasp involving abduction, flexion, and pronation, primarily driven by the thenar intrinsic muscles [31].
• A distally based extensor digiti minimi tendon transfer maximizes adducting force and overcomes reciprocal inhibition to correct a persistently abducted little finger [32].
• There is no significant difference in hand function between border and central finger digital nerve injuries, except for lower grip strength in central finger injuries [33].
• Outcomes for pediatric mutilating hand injuries tend to be better than in adults regarding mobility, sensory return, and appearance [37].
• The quadriga phenomenon is caused by interconnected flexor digitorum profundus tendons and significantly affects clinical situations including strength testing, movement assessment, and rehabilitation exercise selection [39].

• Diagnosis-specific model instruments for outcome after nerve repair at the wrist or distal forearm level include new test instruments for assessment of tactile gnosis [21].
• Supercharged end-to-side anterior interosseous nerve transfer (SETS) exhibits a remarkable role in treating high ulnar nerve damage by supplying intrinsic muscles and allowing for proximal nerve regeneration [27].
• A reliable tendon prosthesis inserted as one stage in tendon reconstruction is an additional step needed to improve results of flexor-tendon reconstructive surgery in hands with severe damage [40].
