The findings in paediatric obstetric brachial palsy differ from those in older patients: a suggested explanation

Abstract: An EMG and nerve-conduction-study protocol has been developed and used in all patients with brachial plexus lesions since 1985. The findings of EMG and nerve-conduction studies in obstetric brachial palsy (OBP) mostly suggest a falsely optimistic prognosis. To analyse this, all subjects were selected with complete avulsion of both roots C5 and C6 and/or complete rupture of the upper trunk verified during operation from a group of 162 infants with OBP (aged 4 to 14 months) and a group of 184 child and adult pat… Show more

“…22 Some authors also believe that "luxury innervation" could also play a role, meaning that polyneuronal innervation could still be present after birth, before the mononeuronal pattern develops. 23 Central abnormalities known as developmental apraxia could also be involved. These abnormalities would result from the sensory-motor deprivation of the cerebral cortex during a critical period of matu- ration.…”

“…An explanation is offered by Vredeveld et al, who described the critical role of the C7 root in spontaneous recovery. In a series of 162 infants with OPBI, evidence of extra innervation of the biceps brachii and deltoid muscles through the C7 root was found in the electrophysiological observations [33]. The surgical objective in cases with complete OBPI is recovery of hand function and establishing the ability to use the affected hand in bimanual activities [9,25,32].…”

“…This procedure has been widely adopted, as it provides an outflow of $ 17,000 to 40,000 myelinated nerve fibers without permanent damage to upper limb function on the healthy side. 8 The motor fibers of the C7 nerve root are dispersive. The anterior division of the C7 root participates in the median and musculocutaneous nerves.…”
