추간판 내장증의 진단

Abstract

Internal disc derangement, first described by H. V. Crock'" is characterized by chronic low back pain, referred type limb pain and other symptoms caused by internal changes of the disc. This condition has been a poorly understood and controversial subject for many years. But we think it is a relatively common disorder causing low back pain and/or limb pain which requires differential diagnosis with disc herniation, spinal stenosis, facet joint syndrome, segmental instability and so on. Sometimes it is undiagnosed or misdiagnosed as other cause of back pain and/or leg pain syndromes since the internal disc derangement have only minimal radiological findings. We are pointing out symptoms and signs of 54 cases of internal disc derangement which was diagnosed by clinical symtoms and MRI findings, presenting illustrative cases for diagnosis and differential diagnosis of internal disc derangement. Of them 17 cases were confirmed by discogram and disco-CT. We think that the better understanding on the clinical characteristics of the internal disc derangement will help to make the more accurate diagnosis and differentiations from other causes of back pain and/or leg pain syndromes.
