The shoulder is a highly movable body joint that allows various movements of the arm. It is a ball and socket joint, where the head of the humerus (upper arm bone) articulates with the socket of the scapula (shoulder blade) called the glenoid. The two articulating surfaces of the bones are covered with cartilage, which prevents friction between the moving bones.
Reverse total shoulder replacement is an advanced surgical technique specifically designed for rotator cuff tear arthropathy, a condition where the patient suffers from both shoulder arthritis and a rotator cuff tear.
Arthroscopy is a minimally invasive diagnostic and surgical procedure performed for joint problems. Shoulder arthroscopy is performed using a pencil-sized instrument called an arthroscope. The arthroscope consists of a light system and camera to project images onto a computer screen for your surgeon to view the surgical site. Arthroscopy is used to treat disease conditions and injuries involving the bones, cartilage, tendons, ligaments, and muscles of the shoulder joint.
The rotator cuff is a group of tendons in the shoulder that provide support and enable a wide range of motion of the shoulder joint. Major injuries can cause rotator cuff tears. A rotator cuff tear is one of the most common causes of shoulder pain in middle-aged adults and older individuals.
The shoulder joint is a ball and socket joint. A 'ball' at the top of the upper arm bone (the humerus) fits neatly into a 'socket', called the glenoid, which is part of the shoulder blade (scapula). The labrum is a ring of fibrous cartilage surrounding the glenoid, which helps in stabilizing the shoulder joint.
The shoulder is formed by three bones, humerus (upper arm bone), scapula (shoulder blade) and clavicle (collar bone). The head of the humerus fits into a cavity at the side of the scapula called the glenoid to form the glenohumeral joint. A projection of bone from the scapula called the acromion joins the outer end of the clavicle to form the acromioclavicular (AC) joint.
