Symptoms of subacromial impingement syndrome

summary

Deseze and Robinson studied the special structure under the acromion and the movement track of the big nodule, and proposed the name of the second shoulder joint. It is also called subacromial joint. The subacromial joint is a series of clinical symptoms and signs caused by the impact of subacromial tissue during shoulder lifting and abduction due to anatomical structure or dynamic reasons.

Symptoms of subacromial impingement syndrome

Impingement can occur in people from 10 to old age. Some patients have a history of shoulder trauma, a considerable number of patients with long-term overuse of the shoulder. Because of rotator cuff, bursa repeatedly injured, tissue edema, bleeding, degeneration and even tendon rupture caused symptoms. Early rotator cuff hemorrhage and edema are similar to the clinical manifestations of rotator cuff rupture, which makes the diagnosis confused. It is very important to distinguish impingement sign from shoulder pain caused by other causes, and to distinguish the stage of impingement sign, which is very important for the diagnosis and treatment of this disease.

In the early stage of acromion impingement syndrome, the friction or bounce of shoulder bone can be felt when the shoulder is moving. In severe cases, shoulder abduction and lifting will cause pain, and the pain range is generally 60 times of abduction and lifting °~ one hundred and twenty ° At this time, the pain is usually in the front of the shoulder. Some patients feel that there is a sound in the shoulder joint in the process of shoulder movement, and they will move the shoulder joint in a larger range, hoping to make this sound disappear. However, it often causes more serious injury, and even causes rotator cuff tear!

Subacromial impingement can lead to supraspinatus tendon abrasion in the early stage, but the symptoms are not obvious at this time. However, as the impact time prolonged, not only the acromion bursa was severely compressed and inflamed, but also the tendon was gradually worn off, resulting in rotator cuff tear.

matters needing attention

Most of subacromial impingement syndrome is related to the change of shoulder brachial rhythm. Therefore, whether conservative treatment or surgical treatment, we should train the scapular muscle strength and restore the normal shoulder brachial rhythm to obtain better rehabilitation effect.
