Shoulder arthritis can be one of three types of arthritis in the glenohumeral joint of the shoulder. The glenohumeral joint is a ball and socket joint, which relies on cartilage to move smoothly and to operate normally.
Shoulder arthritis is a clinical condition in which the joint that connects the ball of the arm bone (humeral head) to the shoulder blade socket (glenoid) has damaged or worn out cartilage. Normally the ends of the bone are covered with hyaline articular cartilage, a surface so smooth that the friction at the joint is less than that of an ice skate on ice. In arthritis, this cartilage is progressively lost, exposing the bone beneath. Shoulder arthritis is characterized by pain, stiffness, and loss of function and often by a grinding on shoulder motion. [1]
One of the three forms of shoulder arthritis is osteoarthritis. Osteoarthritis is the gradual wearing down of the joint cartilage that occurs predominantly in elderly people, and sometimes as the result of overuse in athletes. Post-traumatic arthritis happens after a significant trauma is sustained by the joint, ruining the cartilage. This could be the result of a car accident or after repeated trauma. Rheumatoid arthritis is a disease where the body attacks its own cartilage and destroys it. In each of these cases, cartilage is being destroyed.
The main symptom of shoulder arthritis is pain; this is due to the grinding of the bones against each other because of the lack of cartilage. Pain usually occurs in the front of the shoulder and is worse with motion. People with shoulder arthritis will also experience moderate to severe weakness, stiffness developing over many years, and the inability to sleep on the affected shoulder.
Diagnosis is simple; usually a doctor can diagnose shoulder arthritis by symptoms, but they may ask for an x-ray or MRI for confirmation.
Treatment of shoulder arthritis is usually aimed at reducing pain; there is no way to replace lost cartilage except through surgery. Pain medicines available over-the-counter can be prescribed by the doctor, but another form of treatment is cryotherapy, which is the use of cold compression. Some vitamin supplements have been found to prevent further deterioration; glucosamine sulfate is an effective preserver of cartilage. Another way to prevent the further loss of cartilage would be to maintain motion in the shoulder, because once it is lost, it's difficult to regain. Steps to reduce extreme pain in cases of bad shoulder arthritis can involve the doctor giving injections directly into the shoulder, usually consisting of a steroid mixed with an anesthetic, or even shoulder surgery.[ citation needed ]
For patients with severe shoulder arthritis that does not respond to non-operative treatment, shoulder surgery can be very helpful. Depending on the condition of the shoulder and the specific expectations of the patient, surgical options include total shoulder joint replacement arthroplasty , ‘ream and run’ (humeral hemiarthroplasty with non prosthetic glenoid arthroplasty , and reverse (Delta) total shoulder joint replacement arthroplasty . Research has shown similar outcomes after both reverse and anatomical total shoulder replacement. [2]
Shoulder problems including pain, are one of the more common reasons for physician visits for musculoskeletal symptoms. The shoulder is the most movable joint in the body. However, it is an unstable joint because of the range of motion allowed. This instability increases the likelihood of joint injury, often leading to a degenerative process in which tissues break down and no longer function well.
The human shoulder is made up of three bones: the clavicle (collarbone), the scapula, and the humerus as well as associated muscles, ligaments and tendons.
In dogs, hip dysplasia is an abnormal formation of the hip socket that, in its more severe form, can eventually cause lameness and arthritis of the joints. It is a genetic (polygenic) trait that is affected by environmental factors. It is common in many dog breeds, particularly the larger breeds, and is the most common single cause of arthritis of the hips.
Osteoarthritis (OA) is a type of degenerative joint disease that results from breakdown of joint cartilage and underlying bone. It is believed to be the fourth leading cause of disability in the world, affecting 1 in 7 adults in the United States alone. The most common symptoms are joint pain and stiffness. Usually the symptoms progress slowly over years. Other symptoms may include joint swelling, decreased range of motion, and, when the back is affected, weakness or numbness of the arms and legs. The most commonly involved joints are the two near the ends of the fingers and the joint at the base of the thumbs, the knee and hip joints, and the joints of the neck and lower back. The symptoms can interfere with work and normal daily activities. Unlike some other types of arthritis, only the joints, not internal organs, are affected.
Rotator cuff tendinopathy is a process of senescence. The pathophysiology is mucoid degeneration. Most people develop rotator cuff tendinopathy within their lifetime.
Arthroplasty is an orthopedic surgical procedure where the articular surface of a musculoskeletal joint is replaced, remodeled, or realigned by osteotomy or some other procedure. It is an elective procedure that is done to relieve pain and restore function to the joint after damage by arthritis or some other type of trauma.
Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability, most commonly offered when joint pain is not diminished by conservative sources. It may also be performed for other knee diseases, such as rheumatoid arthritis. In patients with severe deformity from advanced rheumatoid arthritis, trauma, or long-standing osteoarthritis, the surgery may be more complicated and carry higher risk. Osteoporosis does not typically cause knee pain, deformity, or inflammation, and is not a reason to perform knee 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 joint diseases, including osteoarthritis and rheumatoid arthritis.
The shoulder joint 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 and the head of the humerus. Due to the very loose joint capsule that gives a limited interface of the humerus and scapula, it is the most mobile joint of the human body.
The shoulder girdle or pectoral girdle is the set of bones in the appendicular skeleton which connects to the arm on each side. In humans it consists of the clavicle and scapula; in those species with three bones in the shoulder, it consists of the clavicle, scapula, and coracoid. Some mammalian species have only the scapula.
A SLAP tear or SLAP lesion is an injury to the superior glenoid labrum that initiates in the back of the labrum and stretches toward the front into the attachment point of the long head of the biceps tendon. SLAP is an acronym for "Superior Labrum Anterior and Posterior". SLAP lesions are commonly seen in overhead throwing athletes but middle-aged labor workers can also be affected, and they can be caused by chronic overuse or an acute stretch injury of the shoulder.
Hallux rigidus or stiff big toe is degenerative arthritis and stiffness due to bone spurs that affects the metatarsophalangeal joints (MTP) at the base of the hallux.
Shoulder surgery is a means of treating injured shoulders. Many surgeries have been developed to repair the muscles, connective tissue, or damaged joints that can arise from traumatic or overuse injuries to the shoulder.
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.
The capsule of the glenohumeral (shoulder) joint is the articular capsule of the shoulder. It completely surrounds the joint. It is attached above to the circumference of the glenoid cavity beyond the glenoidal labrum, and below to the anatomical neck of the humerus, approaching nearer to the articular cartilage above than in the rest of its extent.
Humeral avulsion of the glenohumeral ligament (HAGL) is defined as an avulsion of the inferior glenohumeral ligament from the anatomic neck of the humerus. In other words, it occurs when we have disruption of the ligaments that join the humerus to the glenoid. HAGL tends to occur in 7.5-9.3% of cases of anterior shoulder instability. Making it an uncommon cause of anterior shoulder instability. Avulsion of this ligamentous complex may occur in three sites: glenoid insertion (40%), the midsubstance (35%) and the humeral insertion (25%). Bony humeral avulsion of the glenohumeral ligament (BHAGL) refers when we have HAGL with bony fracture.
Wrist osteoarthritis is gradual loss of articular cartilage and hypertrophic bone changes (osteophytes). While in many joints this is part of normal aging (senescence), in the wrist osteoarthritis usually occurs over years to decades after scapholunate interosseous ligament rupture or an unhealed fracture of the scaphoid. Characteristic symptoms including pain, deformity and stiffness. Pain intensity and incapability are notably variable and do not correspond with arthritis severity on radiographs.
Trapeziometacarpal osteoarthritis (TMC OA) is, also known as osteoarthritis at the base of the thumb, thumb carpometacarpal osteoarthritis, basilar (or basal) joint arthritis, or as rhizarthrosis. This joint is formed by the trapezium bone of the wrist and the metacarpal bone of the thumb. This is one of the joints where most humans develop osteoarthritis with age. Osteoarthritis is age-related loss of the smooth surface of the bone where it moves against another bone (cartilage of the joint). In reaction to the loss of cartilage, the bones thicken at the joint surface, resulting in subchondral sclerosis. Also, bony outgrowths, called osteophytes (also known as “bone spurs”), are formed at the joint margins.
Post-traumatic arthritis (PTAr) is a form of osteoarthritis following an injury to a joint.
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.
