74 Korean J Pain Vol. 25, No. 2, 2012 a more accurate understanding and education regarding neuroplasty is necessary, as well as further research for a more effective and efficient method and for more appro- priate indications. Specifically, multi-institutional research should be conducted so that operators can discuss the procedure each otherfrom various angles. There should not only be discussionsin the problems of the limits in the treatment, but clarification of the term neuroplasty should also be explained, for example,the differences between neuroplasty and percutaneous epidural adhesiolysis. So there should not be confusion for the operator and patient. As is for any treatment, neuroplasty must also be per- formed with the right indications in order to produce suc- cessful results and patient satisfaction. However, when it is performed indiscriminately, without strict indications, the credibility of the procedure can become depreciated, as well as having the patient bear another burden, which can eventually lead to social problems.
