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 ...
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]
While age [25] and BMI [28] are the main risk factors for osteoarthritis, contributors such as joint trauma and mechanical overloading of joints or joint-instability can accelerate or exacerbate the condition. OA caused by secondary factors such as joint injury or damage to the subchondral bone is referred to as secondary osteoarthritis.
More than 32.5 million adults in the United States have osteoarthritis and it becomes more common with age. Bone on bone: An overview of osteoarthritis types, risks and treatments Skip to main content
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]
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 ...
Medical history (the patient tells the doctor about an injury). For shoulder problems the medical history includes the patient's age, dominant hand, if injury affects normal work/activities as well as details on the actual shoulder problem including acute versus chronic and the presence of shoulder catching, instability, locking, pain, paresthesias (burning sensation), stiffness, swelling, and ...
