Arthroscopy is a minimally invasive surgical technique that involves several small incisions into which a fiber-optic device (arthroscope) and tiny surgical instruments are inserted. Orthopedic surgeons can diagnose and treat many different shoulder conditions with arthroscopy, while patients can benefit from less tissue damage, shorter recovery times, less scarring and less post-operative pain. This technique also avoids cutting any muscles or tendons in order to gain access to the affected area.
Shoulder arthroscopy is often performed to confirm a diagnosis after a physical examination and other imaging procedures have been performed. Some conditions can also be treated during the same procedure by inserting a few additional instruments into the joint area.
Arthroscopy can be used to treat many conditions that affect the shoulder joint. Shoulder arthroscopy, also known as shoulder scope, can be used to treat:
- Rotator cuff tears
- Labral tears
- Impingement syndrome
- Biceps tendonitis
- AC joint arthritis
While arthroscopy offers many benefits over a traditional open procedure, it is not for everybody. Some conditions, especially those that are not easily visible with the arthroscopic camera, may be better suited for traditional surgery. Your doctor will decide which type of procedure is right for you.
Shoulder Dislocation Treatment
The shoulder is a "ball-and-socket" joint where the "ball" is the rounded top of the arm bone (humerus) and the "socket" is the cup (glenoid) of the shoulder blade. A layer of cartilage called the labrum cushions and deepens the socket. A dislocation occurs when the humerus pops out of its socket, either partially or completely. As the body's most mobile joint, able to move in many directions, the shoulder is most vulnerable to dislocation.
Dislocation causes pain and unsteadiness in the shoulder. Other symptoms may include swelling, numbness, weakness and bruising. The majority of dislocations occur when the humerus slips forward, a condition called anterior instability. This may happen during a throwing motion. The humerus is also capable of dislocating backwards or downwards. In most cases, the dislocated shoulder can be manipulated back into place by a doctor in a process known as closed reduction.
Complications of shoulder dislocation or reduction can include a labrum or cartilage tear, a lesion on the glenoid bone after the humerus strikes it, tendon or ligament injuries, and blood vessel and nerve damage. Shoulders that have dislocated once are more likely to dislocate in the future, potentially resulting in chronic shoulder instability and weakness.
