For which of the following scenarios is this an appropriate line of treatment? Neurol India, 2016. A “pre-fixed” brachial plexus is formed predominantly from the C4-C7 roots and a “post-fixed” brachial plexus is formed predominantly from the C2-T2 roots.2, For purpose of treatment and prognosis, the injury on the plexus is divided into, Based on whether the injury is proximal or distal to the dorsal root ganglion (DRG), they are further characterized as preganglionic and postganglionic, respectively. Roots – These refer to the starting point of the Brachial Plexus, formed by the spinal nerves C5, C6, C7, C8, and T1. Wilson, T.J., K.W. 40(6): p. 1166-9. Daly, C.A., S.H.

A 3-month-old is brought to clinic for evaluation of a right upper extremity abnormaility present since birth. It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow. The indications for immediate/early repair (within 3–4 weeks postinjury) are (i) sharp, open injury, (ii) associated vascular injuries, (iii) flail limb with severe deafferentation pain, and (iv) preganglionic injury with pseudomeningoceles on magnetic resonance myelography.

Spontaneous recovery is rare with complete axonal discontinuity, manifested by complete absence of CMAPs, absence of motor unit action potentials (MUAPs) despite good effort, and abnormal spontaneous activity.2 With complete conduction block, MUAPs may be absent but distal CMAPs should still be present without significant abnormal spontaneous activity.34 It is important to note that many of the proximal nerves cannot be directly assessed, and root stimulation studies are necessary to detect proximal conduction block.
