Musculoskeletal System and Connective Tissue (M00-M99).
- Bursitis (inflammation of the bursa).
- Impingement syndrome (English “collision”) – the symptomatology of this syndrome is based on the presence of a constriction of the tendon structure in the shoulder joint and thus impaired function of joint mobility. It is mostly caused by degeneration or entrapment of capsular or tendon material. Degeneration or injury of the rotator cuff is the most common cause here. Symptom: Affected patients can barely lift their arm above shoulder height due to the increasing impingement of the supraspinatus tendon. The actual impingement occurs subacromially, which is why this is called subacromial syndrome (short: SAS).
- Tendinosis calcarea of the shoulder (calcified shoulder) – calcification mostly in the area of the attachment tendon of the supraspinatus muscle; prevalence (disease frequency): about 10% in asymptomatic patients / about 50% becomes symptomatic; often spontaneously regressive (regressive); more men than women; frequency of bilateral: 8-40%.
- Injuries to the ligaments
