Ahmed et al  in their study on functional outcome of brachial plexus found no difference in DASH scores of supra- and infra-clavicular injuries, but patients with root avulsion
had worse DASH scores.
Background: Root avulsion
to all 5 roots of the brachial plexus is a common presentation and keeps a major reconstructive challenge.
Allieu Y, Privat JM, Bonnel F: Paralysis in root avulsion
of the brachial plexus: Neurotization by the spinal accessory nerve, in Terzis JK: Microreconstruction of nerve injuries.
Otherwise, a root avulsion
with intact MFL did not significantly affect contact mechanics .
These tender areas are believed to be areas of nerve root avulsion
or constriction, for some other reason than the bony neuroforaminal stenosis, as is seen in most other patients.
The child has nerve root avulsion
at C7 with damage to adjacent nerve trunks at C5-C6.
(8) This manner of forceful separation typically results in pre-ganglionic root avulsion
or post-ganglionic rupture of the upper roots (C5-C6) while sparing the lower roots (C7, C8, T1).
The cause of the recurrent SAH is determined on imaging in only 50% of cases (3) and includes dural pathology, postsurgical CSF cavity with neovascularity, bleeding central nervous system (CNS) tumours (ependymoma, oligodendroglioma and astrocytoma), vascular malformations (arteriovenous malformations and cavernous malformation near the brain's surface), aneurysms, and in the spinal cord--tumours, arteriovenous malformations and traumatic nerve root avulsion
(phantom arm) following cervical root avulsion
: Effect of
Brachial plexus root avulsion
could be clinically intervented using the contralateral healthy C7 nerve-root as autologous graft.
(1) CT myelogram is also useful in diagnosing CSF leak and nerve root avulsion
On MRI, spinal cord was normal but there was nerve root avulsion
injury with pseudomeningocele on right at C6/C7 level and edema of brachial plexus on left side.
