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 ...
Arthritis mutilans presents in about 5–16% of psoriatic arthritis cases, involves osteolysis of the DIP and PIP joints, and can include bone edema, bone erosions, and new bone growth. [8] Most often psoriatic arthritis is seronegative for rheumatoid factor (occurring in only about 13% of cases [9]), and has genetic risk factor overlap with ...
Osteoarthritis can cause a crackling noise (called "crepitus") when the affected joint is moved, especially shoulder and knee joint. A person may also complain of joint locking and joint instability. These symptoms would affect their daily activities due to pain and stiffness. [13]
It affects humans and other animals, notably dogs, but also occurs in cats and horses. It can affect both the larger (ie. knee, hip, shoulder, etc.) and the smaller joints (ie. fingers, toes, foot, etc.) of the body. The disease is caused by daily wear and tear of the joint. This process can progress more rapidly as a result of injury to the joint.
For example, psoriatic arthritis can cause both peripheral and axial symptoms. [7] Likewise, reactive arthritis can transform into chronic axial spondyloarthritis. [8] All are considered inflammatory rheumatic disorders because they involve immune system-mediated attacks on the joints, muscles, bones and organs. [9]
When the toes are dorsiflexed in the propulsive phase of gait, the plantar fascia becomes tense, resulting in elevation of the longitudinal arch and shortening of the foot (see 3A). One can liken this mechanism to a cable being wound around the drum of a windlass (see 3B); the plantar fascia being the cable, the metatarsal head the drum, and ...
A diagram showing how rheumatoid arthritis affects a joint Hand deformity, sometimes called a swan deformity, in an elderly person with rheumatoid arthritis. Arthritis of joints involves inflammation of the synovial membrane. Joints become swollen, tender and warm, and stiffness limits their movement. With time, multiple joints are affected ...
The shoulder joint is composed of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) (see diagram). Two joints facilitate shoulder movement. The acromioclavicular (AC) joint is located between the acromion (part of the scapula that forms the highest point of the shoulder) and the clavicle.
