The outcome is best with neurapraxia and worst with neurotmesis.5,22,23 EDX is the tool of choice for the quantitative evaluation of the injured peripheral nerves.20-23 It is technically demanding but is of great value in localising the lesion, assessing the underlying pathophysiology, estimating the degree of severity, and predicting subsequent prognosis.20-23 In Pakistan, EDX services are not widely available and few physicians are adequately trained to handle them.
Overall, the most common cause of radial nerve palsy in closed fractures is neurapraxia, and it is likely that our delayed radial nerve palsy was due to nerve contusion/neurapraxia [9].
Depending on the severity of the initial insult, the resulting injury can range anywhere from recoverable neurapraxia to the irreversible axonotmesis [16].
In many cases it was impossible to evaluate the prognosis, except in forms of neurapraxia: the functional outcome was affected by sensitivity and pain factors.
