Abstract
In order to judge the indication for surgical procedures and prognosis of the peripheral nerve injuries, the authors carry out most often nerve conduction test as one of electrodiagnostic methods. And in addition, recently, in seven cases of peripheral nerve injuries, we have conducted the neurographic studies to estimate the indication of surgical procedures.
The authors compared the neurographic studies with the nerve conduction tests, and the following results were obtained:
1) Nerve conduction test: It is one of the excellent diagnostic methods of peripheral nerve injuries to decide the degree (neurapraxia, Wallerian degeneration or mixed type), localization, and the presence of continuity, partially continuity or discontinuity of lesion of the nerve. Therefore, this method is useful for the judgement of the prognosis and for the early decision of the opportunity for surgical procedures and method.
2) Neurography: This method is also useful as one of the diagnostic methods, especially may be more beneficial to confirm whether the nerve sutures or the transposition of nerve are satisfactory or not.
However, we must have in mind the secondary reaction, because the contrast medium used was not absorbed for a long time in some cases by our experience.
