Nerve Recovery

Autologous nerve grafting is the most commnly used operative technique in delayed primary, or secondary nerve repair after the peripheral nerve injuries. The aim of this procedure is to overcome nerve gaps that results from the injury itself, fibrous and elastic retraction forces, resection of the damaged parts of the nerve, position of the articulations and mobilisation of the nerve. In this study we analyse the results of operated patients with transections and lacerations of the peripheral nerves from 1979 to 2000 year. Gunshot injuries have not been analyzed in this study. The majority of the injuries were in the upper extremity (more than 87% of cases). Donor for nerve transplantation had usually been sural nerve, and only occasionally medial cutaneous nerve of the forearm was used. In about 93% of cases we used interfascicular nerve grafting, and cable nerve grafting was performed in the rest of them. Most of the grafts were 1 do 5 cm long (70% of cases). Functional recovery was achieved in more than 86% of cases, which is similar to the results of the other authors. Follow up period was minimum 2 years. We analyzed the influence of different factors on nerve recovery after the operation: patient?s age, location and the extent (total or partial) of nerve injury, the length of the nerve graft, type of the nerve, timing of surgery, presence of multiple nerve injuries and associated osseal and soft tissue injuries of the upper and lower extremities.

Thoracic Nerve

: Our article focuses on various surgical treatments and outcomes in patients who had upper and or lower extremity musculoskeletal disorders due to peripheral nerve injuries. Here, we mainly discuss the benefits of the Nath method of surgical management in infants, children (preteen and teen), and adult patients in the following four categories of peripheral nerve damage. Brachial Plexus Injury and Upper Extremity Musculoskeletal Dysfunctions: Improvements in detail are discussed in obstetric brachial plexus palsy patients, who had the soft tissue surgical procedure, modified Quad, and the novel osseous operative technique, triangle tilt at our clinic. Upper Trunk of Brachial Plexus and Long Thoracic Nerve Damage and Winging Scapula: There are at least 18 categories of causation/etiology of upper plexus and long thoracic nerve lesions in 575 patients who visited our clinic with winging scapula, limited shoulder movements, and or pain. Further, we discuss the results of the excellent recovery of hundreds of these patients, who had decompression and neurolysis of the upper trunk of brachial plexus and long thoracic nerve. Peroneal Nerve Lesion and Foot Drop:: Our management of foot drop by nerve transfers to the deep peroneal nerve is discussed. Sural Nerve Grafting to Cavernous Nerve Impairment after Prostatectomy or Genital Surgery: We also discuss briefly our experience and results of the sural nerve grafting, which restores the function of cavernous nerves resected during radical prostatectomy. Conclusion: The lead author (RKN) has developed and implemented several innovative new surgical approaches as a reconstructive microsurgeon. These surgical techniques have proven clinical and functional improvements in patients with upper and lower extremity musculoskeletal disorders due to peripheral nerve injuries.

Nerve Transfers

Abstract Brachial plexus and peripheral nerve injuries are exceedingly common. Traditional nerve grafting reconstruction strategies and techniques have not changed significantly over the last 3 decades. Increased experience and wider adoption of nerve transfers as part of the reconstructive strategy have resulted in a marked improvement in clinical outcomes. We review the options, outcomes, and indications for nerve transfers to treat brachial plexus and upper- and lower-extremity peripheral nerve injuries, and we explore the increasing use of nerve transfers for facial nerve and spinal cord injuries. Each section provides an overview of donor and recipient options for nerve transfer and of the relevant anatomy specific to the desired function.

Axon Collaterals

Motor and sensory proprioceptive axons reinnervate muscles after peripheral nerve transections followed by microsurgical reattachment; nevertheless, motor coordination remains abnormal and stretch reflexes absent. We analyzed the possibility that permanent losses of central IA afferent synapses, as a consequence of peripheral nerve injury, are responsible for this deficit. VGLUT1 was used as a marker of proprioceptive synapses on rat motoneurons. After nerve injuries synapses are stripped from motoneurons, but while other excitatory and inhibitory inputs eventually recover, VGLUT1 synapses are permanently lost on the cell body (75–95% synaptic losses) and on the proximal 100 μm of dendrite (50% loss). Lost VGLUT1 synapses did not recover, even many months after muscle reinnervation. Interestingly, VGLUT1 density in more distal dendrites did not change. To investigate whether losses are due to VGLUT1 downregulation in injured IA afferents or to complete synaptic disassembly and regression of IA ventral projections, we studied the central trajectories and synaptic varicosities of axon collaterals from control and regenerated afferents with IA-like responses to stretch that were intracellularly filled with neurobiotin. VGLUT1 was present in all synaptic varicosities, identified with the synaptic marker SV2, of control and regenerated afferents. However, regenerated afferents lacked axon collaterals and synapses in lamina IX. In conjunction with the companion electrophysiological study [Bullinger KL, Nardelli P, Pinter MJ, Alvarez FJ, Cope TC. J Neurophysiol (August 10, 2011). doi:10.1152/jn.01097.2010], we conclude that peripheral nerve injuries cause a permanent retraction of IA afferent synaptic varicosities from lamina IX and disconnection with motoneurons that is not recovered after peripheral regeneration and reinnervation of muscle by sensory and motor axons.
