Selective Restoration of Motor Function in the Ulnar Nerve by Transfer of the Anterior Interosseous Nerve

Case report: Double nerve transfer of the anterior and posterior interosseous nerves to treat a high ulnar nerve defect at the elbow

“…Two cadaver studies [2,3] revealed that the AIN and DBUN had the same number of axons and the same diameter, making it possible to suture the nerves together in a satisfactory way. Robert et al [5] reported that these two nerves were no more than 10 mm apart once the fascicles had been individualized.…”

“…In 1999, Battiston and Lanzetta [1] reported a new double nerve transfer technique where the anterior interosseous nerve (AIN) and the palmar cutaneous branch of the median nerve were connected to the deep and superficial branches of the ulnar nerve (DBUN and SBUN). In later studies [2][3][4], it was shown that the DBUN and the anterior interosseous nerve had the same diameter and the same number of axons. In a cadaver study, Robert et al [5] concluded that these two motor branches could be directly sutured together.…”

Involuntary, Electrically Excitable Nerve Transfer for Denervation: Results From an Animal Model

“…Similarly, C7 ASIA (grade 4, IC) patients could have a paralyzed terminal anterior interosseous nerve to the pronator quadratus transfer to the denervated ulnar intrinsic branch. 22,23 Such a transfer might prevent or reverse intrinsic minus hand posture. However, one potential issue with this technique is that it will create a new involuntary and degenerated peripheral nerve (ie, the distal segment of the donor nerve).…”

Brachial Plexus Variations in Human Fetuses

“…It occurs when growing nerve fibers reach a denervated peripheral target and reestablish connections between the neuron and motor or sensory end organs. Neurotization has been attempted with a variety of donor nerves, including intercostal nerves, spinal accessory nerves, motor branches of the cervical plexus, phrenic nerves, and collateral motor branches of the BP (1,2,12,20,26,27,31,(37)(38)(39)41).…”
