Diagnosis
The diagnosis may be confirmed by an EMG examination in 5 to 7 days. The evidence of denervation will be evident. If there is no nerve conduction 72 hours after the injury, then avulsion is most likely.. The most advanced diagnostic method is MR imaging of the brachial plexus using a high Tesla MRI scanner like 1.5 T or more. MR help us in the assessment of the injuries in specific context of site, extent and the nerve roots involved. in addition, assessment of the cervical cord, post traumatic changes in soft tissues may also be visualised.
