Capsule is a diffuse lesion of the capsule and synovial membrane of the shoulder joint, often leading to a prolonged disability of the patient. In most cases, capsulitis occurs in persons aged 50 to 70 years. The disease is rare until age 40, almost always a secondary form (induced by other diseases). Women are sick more often than men (ratio 3: 1-5: 1). The beginning usually spontaneous, without any previous events, is subacute. It begins with pain in the shoulder joint, which eventually grows. In this case, the pain is little associated with any particular movement, often amplified at night and lying on the affected shoulder. Then the pain gradually decreases, and the phase of "stiffness" begins - the actual painless limitation of the volume of movements in the joint. A characteristic type of patient during this period of the disease and gave the name of the disease - "ankylosing" or "frozen shoulder". This phase is followed by a period of resolution, during which the volume of movements in the joint is gradually restored. In most cases, the disease ends with recovery, but half of patients do not fully return to their original volume of movements, which, however, does not prevent them from daily life. If the conservative methods of treatment are ineffective, arthroscopic manipulations on the affected shoulder joint are indicated.
Indications: absolute indications for arthroscopy of the shoulder joint are absent. There are a number of diseases in which arthroscopy of the shoulder joint can help in diagnosis and treatment:
- chronic pain syndrome of the shoulder joint
- partial or complete damage to the rotator cuff
- impidge-shoulder joint syndrome
- damage to the cartilaginous lip of the articular process of the scapula
- instability of the shoulder joint
- presence of intraarticular bodies (chondromatosis)
- synovitis in rheumatoid arthritis
- damage to the long head of the biceps arm
Contraindications: Infectious changes on the skin of the shoulder joint
Advantage of arthroscopy:
- absence of large cuts;
- there is no need for prolonged hospitalization;
- absence of trauma of soft tissues around the joint;
- the possibility of a more thorough examination of the joint (especially the posterior sections, inaccessible to inspection during a routine operation);
- more delicate handling of intraarticular formations;
- the possibility of early recovery of movements after surgery.
It is possible to treat this pathology with the help of medical-diagnostic arthroscopy of the shoulder joint.
