Objectives
Many studies have elaborated on the role of magnetic resonance neurography (MRN) in evaluating traumatic brachial plexopathies. Most of these deal with MR findings in adult traumatic plexopathies or children with obstetric brachial plexus palsy (OBPP). Hence, the authors felt the need for this particular study, which focuses on MRN findings in children with non-obstetric traumatic brachial plexus palsy, to find out the distribution and severity of injuries in these patients.
Methods
This was a single-institution, prospective study conducted between April 2015 and June 2016. All children presenting to the hospital with features of brachial plexopathy and a history of non-obstetric trauma were included in the study.
Results
At MRN, we looked for signs of injury at three levels: roots, trunks and cords. Signs of injury were found at the level of the roots in 22 patients (88%), at the level of the trunks in 20 patients (80%) and at the level of the cords in 22 patients (88%).
Conclusions
This study, conducted on children suffering from non-obstetric, traumatic brachial plexopathy returned some interesting conclusions including that when the paediatric plexus is injured, the injury is severe and multi-level, with a very high incidence of root injuries.
Key Points
• Brachial plexus injury in paediatric age group is a devastating injury.
• The most common cause of this is trauma sustained during birth.
• Other causes include road traffic accidents and blunt injury.
• MR neurography has revolutionised the diagnosis of brachial plexopathy
