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 ...
Muscle loss around the shoulder may also occur. [1] Onset is gradual over weeks to months. [2] Complications can include fracture of the humerus or biceps tendon rupture. [2] The cause in most cases is unknown. [1] The condition can also occur after injury or surgery to the shoulder. [2] Risk factors include diabetes and thyroid disease. [1] [4 ...
FRAX integrates clinical risk factors and bone mineral density at the femoral neck to calculate the 10-year probability of hip fracture and the 10-year probability of a major osteoporotic fracture (clinical spine, forearm, hip or shoulder fracture). [2]
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 ...

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]
The main risk factors for osteoarthritis are age [2] [3] and body mass index, [4] [3] as such, OA is predominantly considered a disease of aging. [5] [6] As the body ages, catabolic factors begin to predominate over anabolic factors resulting in a reduction of extracellular matrix gene expression [7] and reduced cellularity [8] [7] in articular ...
Post-traumatic osteoarthritis is the most common variation of post-traumatic arthritis. [3] Between 20 and 50% [4] of all osteoarthritis cases are preceded by post-traumatic arthritis. Patients having post-traumatic osteoarthritis are usually younger than osteoarthritis patients without any previous physical injuries. [5]
