Chronic Anterior Instability and Impingement Syndrome

Mehmet İşyar, M.D. Prof

Chronic anterior instability and internal impingement syndrome is a term that refers to two different but sometimes co-existing health problems that occur in the shoulder joint. These two conditions are associated with the tendons, muscles and connective tissues around the shoulder joint and are usually caused by overuse of the shoulder or traumatic events.

Chronic Anterior Instability: This condition refers to instability in the anterior part of the shoulder joint as a result of repetitive injuries or overuse. When the tissue or ligaments in the shoulder joint, called the labrum, are torn or weakened, unwanted mobility can occur in the front of the shoulder. This can be described as “dislocation” or “dislocation sensation” of the shoulder and can be painful.
Internal Impingement Syndrome: This syndrome refers to a condition in which tendons or soft tissues in the shoulder joint are compressed by the shoulder bones. This impingement can cause friction and irritation of the tendons when lifting or rotating the shoulder. Anterior impingement syndrome can present with symptoms such as pain, weakness and limitation of shoulder movements.

Diagnosis of chronic anterior instability and internal impingement syndrome is usually based on physical examination, imaging tests (for example, magnetic resonance imaging – MRI) and the patient’s symptoms. Treatment options may vary depending on the severity of the patient’s symptoms and the type of condition. Treatment options include
