We have examined the arthrograms in 164 cases (176 joints) of the frozen shoulder and classified them into 5 types based on the shape of the contrast medium. In the type showing diminution of the inferior pouch, there were many cases in which the range of motion was markedly limited, the capacity of the joint was small, the response to the anesthetic injection to the suprascapular nerve was poor and the period of treatment was long. While in the type showing the normal arthrogram, the improvement rating for the range of motion was high and the period of treatment was short. Although not all the pathologic conditions of the frozen shoulder are visualized, the arthrography may be useful as an auxiliary diagnostic method since it can predict the clinical course to some extent.
