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 ...
The biggest risk factor for osteoarthritis seems to be age, and often the cartilage degrades over longer periods of time, which makes it really hard to pinpoint one single culprit. As I mentioned earlier, inflammation also seems to be involved, and there are a number of proinflammatory cytokines like IL-1, IL-6, and TNF, among others, that seem ...
The risk of osteoarthritis increases with aging, history of joint injury, or family history of osteoarthritis. [18] However exercise, including running in the absence of injury, has not been found to increase the risk of knee osteoarthritis. [19] [20] Nor has cracking one's knuckles been found to play a role. [21]
Several factors contribute to the development of arthritis, differing on the type of arthritis. [2] [6] Osteoarthritis occurs from damage to joint cartilage from prior injury or long-term wear-and-tear, resulting in bone-to-bone contact and grinding. [6] The resulting arthritis can occur over years, or be worsened by further injury or infection ...
Osteosclerosis is a disorder characterized by abnormal hardening of bone and an elevation in bone density. It may predominantly affect the medullary portion and/or cortex of bone. Plain radiographs are a valuable tool for detecting and classifying osteosclerotic disorders. [1] [2] It can manifest in localized or generalized osteosclerosis.
Bone marrow edema is usually caused by or associated with pre-existing conditions. Numerous epidemiological studies in patients with bone marrow edema have found certain patterns of characteristics among the participants; for example, certain medical conditions such as osteoporosis are substantial risk factors for developing bone marrow edema. [39]
Risk factors include bone fractures, joint dislocations, alcoholism, and the use of high-dose steroids. [1] The condition may also occur without any clear reason. [1] The most commonly affected bone is the femur (thigh bone). [1] Other relatively common sites include the upper arm bone, knee, shoulder, and ankle. [1]
A bone fracture of the shoulder involves a partial or total crack through one of the three bones in the shoulder, the clavicle, the scapula, and the humerus. The break in a bone usually occurs as a result of an impact injury, such as a fall or blow to the shoulder. Fractures usually involve the clavicle or the neck (area below the ball) of the ...
