• The cervicodorsal outlet is not an anatomic structure but the region in which the nerves and blood vessels leave the neck and thorax and are transmitted to the upper extremity. Compression or stretching of the neurovascular structures in this region can cause pain, numbness, and discomfort in the shoulder and upper extremity, but the complaints are usually vague and frequently there are no objective findings. The majority of patients with this syndrome respond favorably to conservative treatment consisting of physical therapy, reassurance, and avoidance of activities or positions bringing on the complaints.
