[The uncus exostoses syndrome and its treatment by means of the decompression operation of the vertebral artery (author's transl)].

In degenerative changes of the mobile segments of the cervical vertebral column, deformations of the uncovertebral gaps (joints), resembling exostoses, with a lateral or dorsolateral spread, are frequently seen. This involves irritation of neighbouring structures, such as the arteria and vena vertebralis including the nervus vertebralis or the corresponding nerve roots. This produces a disease pattern with a cervico-encephalic and cervico-brachial mixed pattern of symptoms. Angiography of the a. vertebralis proves the localisation and extent of the disturbance. The decompression of the a. vertebralis according to the method described by A. Jung offers good chances of curing the disease. The author's own operative results are presented and discussed.
