Shoulder Replacement
Shoulder replacement is a surgical procedure in which all or part of the glenohumeral joint is replaced by a prosthetic implant. Such joint replacement surgery generally is conducted to relieve arthritis pain or fix severe physical joint damage. Shoulder replacement surgery is an option for treatment of severe arthritis of the shoulder joint. Arthritis is a condition that affects the cartilage of the joints. As the cartilage lining wears away, the protective lining between the bones is lost. When this happens, painful bone-on-bone arthritis develops. Severe shoulder arthritis is quite painful, and can cause restriction of motion. While this may be tolerated with some medications and lifestyle adjustments, there may come a time when surgical treatment is necessary. Most shoulder replacements last longer than 10 years. A global study found that patients can expect large and long-lasting improvements in pain, strength, range of movement, and their ability to complete everyday tasks ...

Glenohumeral Joint
The shoulder joint (or glenohumeral joint from Greek ''glene'', eyeball, + -''oid'', 'form of', + Latin ''humerus'', shoulder) is structurally classified as a synovial ball-and-socket joint and functionally as a diarthrosis and multiaxial joint. It involves an articulation between the glenoid fossa of the scapula (shoulder blade) and the head of the humerus (upper arm bone). Due to the very loose joint capsule, it gives a limited interface of the humerus and scapula, it is the most mobile joint of the human body. Structure The shoulder joint is a ball-and-socket joint between the scapula and the humerus. The socket of the glenoid fossa of the scapula is itself quite shallow, but it is made deeper by the addition of the glenoid labrum. The glenoid labrum is a ring of cartilaginous fibre attached to the circumference of the cavity. This ring is continuous with the tendon of the biceps brachii above. Spaces Significant joint spaces are: * The normal glenohumeral space is 4†... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Joint Replacement
Joint replacement is a procedure of orthopedic surgery known also as arthroplasty, in which an arthritic or dysfunctional joint surface is replaced with an orthopedic prosthesis. Joint replacement is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies. Joint replacement surgery is often indicated from various Arthropathy, joint diseases, including osteoarthritis and rheumatoid arthritis. Joint replacement has become more common, mostly with knee replacement, knee and hip replacements. About 773,000 Americans had a hip or knee replaced in 2009.Joint Replacement Surgery and You.

Arthritis
Arthritis is a general medical term used to describe a disorder that affects joints. Symptoms generally include joint pain and stiffness. Other symptoms may include redness, warmth, Joint effusion, swelling, and decreased range of motion of the affected joints. In certain types of arthritis, other organs such as the skin are also affected. Onset can be gradual or sudden. There are several types of arthritis. The most common forms are osteoarthritis (most commonly seen in weightbearing joints) and rheumatoid arthritis. Osteoarthritis usually occurs as an individual ages and often affects the hips, knees, shoulders, and fingers. Rheumatoid arthritis is an autoimmune disorder that often affects the hands and feet. Other types of arthritis include gout, lupus, and septic arthritis. These are inflammatory based types of rheumatic disease. Early treatment for arthritis commonly includes resting the affected joint and conservative measures such as heating or icing. Weight Weight ...

Subscapularis
The subscapularis is a large triangular muscle which fills the subscapular fossa and inserts into the lesser tubercle of the humerus and the front of the capsule of the Glenohumeral joint, shoulder-joint. Structure The subscapularis is covered by a dense fascia which attaches to the scapula at the margins of the subscapularis' attachment (origin) on the scapula. The muscle's fibers pass laterally from its origin before coalescing into a tendon of insertion. The tendon intermingles with the Glenohumeral, glenohumeral (shoulder) joint capsule.

Glenoid
The glenoid fossa of the scapula or the glenoid cavity is a bone part of the shoulder. The word ''glenoid'' is pronounced or (both are common) and is from , "socket", reflecting the shoulder joint's ball-and-socket form. It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula. It is directed laterally and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest. This cavity forms the glenohumeral joint along with the humerus. This type of joint is classified as a synovial, ball and socket joint. The humerus is held in place within the glenoid cavity by means of the long head of the biceps tendon. This tendon originates on the superior margin of the glenoid cavity and loops over the shoulder, bracing humerus against the cavity. The rotator cuff also reinforces this joint more specifically with the supraspinatus tendon to hold the head of the humerus in the glenoid cav ...

Jules-Émile Péan
Jules-Émile Péan (; 29 November 1830 – 20 January 1898) was one of the great French surgeons of the 19th century. Péan was born in 1830 in Marboué, french department of Eure-et-Loir. He studied at the college of Chartres and then studied medicine in Paris under Auguste Nélaton. He was appointed a doctor in 1861 and worked at St. Antoine and St. Louis up to 1893. He then created with its expenses the international hospital. He wrote two volumes of private clinics (1876 and 1890). He was elected to the French Académie Nationale de Médecine on November 22, 1887, and was awarded the rank of Commander of Legion of Honor in 1893. He died on January 20, 1898, in Paris. A street, Rue Péan, was named after him in Châteaudun, Cloyes-sur-le-Loir and Paris. Péan was very admired and a follower of hygiene, he disputed the discoveries of Louis Pasteur. He refused to dissect corpses and operated preferably in residence. Although a teacher, he was never named professor. He was t ...

Reverse Shoulder Replacement
Reverse shoulder replacement is a type of shoulder replacement in which the normal ball and socket relationship of glenohumeral joint is reversed, creating a more stable joint with a fixed fulcrum. This form of shoulder replacement is utilized in situations in which conventional shoulder replacement surgery would lead to poor outcomes and high failure rates. Originally considered a salvage procedure, the combination of improved design features and excellent clinical outcome data has led to reverse shoulder replacement largely replacing shoulder hemiarthroplasty for most indications, and even challenging conventional anatomic shoulder replacement in many countries as the most commonly performed shoulder replacement procedure. Medical uses Historically, the primary indication to perform reverse shoulder replacement was cuff tear arthropathy, which consists of advanced glenohumeral arthritis in the presence of a massive rotator cuff tear. As reverse shoulder replacement has become ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
