Shoulder bottleneck syndrome

The bottleneck syndrome or impingement syndrome of the shoulder is a structural anatomical narrowing in the subacromial space with frequent inflammation of the bursa (bursitis subacromialis). The space between the humeral head and the acromion is crossed by the tendons of the rotator cuff. The narrowing of the cuff causes mechanical friction and even bruising oder compression of the tendons, e.g. when the arm is raised or rotated. A spur-like extension at the lower front edge of the acromion is often responsible for this. The so-called impingement situation, which causes the (resulting) narrowness, also leads to inflammation with night pain and, in the course of the disease, a restriction of movement. If the shoulder impingement syndrome
lasts longer, the rotator cuff tendons - especially the supraspinatus tendon - can be mechanically damaged and also ruptured.

In this case, arthroscopy / minimally invasive surgery is recommended. During this procedure, the inflamed tissue (bursa) is removed as well as the bony bottleneck. The bony spur is removed with a bone cutter. If necessary, a tendon suture can also be performed if the tendon has already been damaged.

To diagnose shoulder imgingement, an ultrasound and/or magnetic resonance tomography is performed in addition to the medical history and a clinical examination. In the early stages of the disease, the extent of the complaint can be temporarily alleviated by a syringe treatment (by means of an injection) under the acromion.
