A Patient's Guide to Shoulder Arthroscopy
The use of arthroscopy (arthro means joint and scopy means look) has revolutionized many different types of orthopedic surgery. During a shoulder arthroscopy, a small video camera attached to a fiber-optic lens is inserted into the shoulder joint to allow a surgeon to see without making a large incision. Today the shoulder is one of the joints in which the arthroscope is commonly used to both diagnose problems and to perform surgical procedures inside the joint.
This guide will help you understand
The shoulder is made up of three bones: the scapula (shoulder blade), the humerus (upper arm bone), and the clavicle (collarbone). A part of the scapula, called the glenoid, forms the socket of the shoulder. The glenoid is very shallow and flat, shaped somewhat like a dinner plate rather than a bowl. The humeral head forms the ball portion of the joint. Both the glenoid and the humeral head are covered with articular cartilage. Articular cartilage is the smooth, white material that covers the ends of bones in most joints. Articular cartilage provides a slick, rubbery surface that allows the bones to glide over each other as they move. Articular cartilage also functions as a shock absorber.
The rotator cuff connects the humerus to the scapula. The rotator cuff is formed by the tendons of four muscles: the supraspinatus, infraspinatus, teres minor, and subscapularis. Tendons attach muscles to bones. Muscles move the bones by pulling on the tendons. The rotator cuff helps raise and rotate the arm. As the arm is raised, the rotator cuff also keeps the humerus tightly in the shoulder socket, the glenoid. The upper part of the scapula that makes up the roof of the shoulder is called the acromion.
The shoulder joint is surrounded by a water tight pocket called the joint capsule. This capsule is formed by the rotator cuff tendons, ligaments, connective tissue and synovial tissue. When the joint capsule is filled with sterile saline and is distended, the surgeon can insert the arthroscope into the pocket that is formed, turn on the lights and the camera and see inside the shoulder joint as if looking into an aquarium. The surgeon can see nearly everything that is inside the shoulder joint including: (1) the joint surfaces of the glenoid socket and the humeral head (2) the rotator cuff tendons, (3) the glenoid labrum and (4) the synovial lining of the joint.
The arthroscope can also be placed in the space outside the shoulder joint known as the subacromial bursa. This bursa is a water tight pocket that sits above the shoulder joint. By placing the arthroscope into this space, the surgeon can see the underside of the distal end of the clavicle (collarbone) and the acromion as well as the joint that is for...
