Discography is one of the diagnostic technique for the lumbar disc lesion.
The correlation between discogram and pain response were investigated on 362 discs in 161 cases.
The results were as follows;
1. Most of normal discs did not reveal pain response. On the other hand, most of pathological discs, particularly in anterior and posterior protrusion revealed pain response.
2. Pain response tend to decrease with the progression of degenerative processes of discs.
Therefore, it is important to evaluate the discogram itself and its pain response for the diagnosis of lumbar disc lesion.
