Tendinopathy is a type of tendon disorder that results in pain, swelling, and impaired function. [2] The pain is typically worse with movement. [2] It most commonly occurs around the shoulder (rotator cuff tendinitis, biceps tendinitis), elbow (tennis elbow, golfer's elbow), wrist, hip, knee (jumper's knee, popliteus tendinopathy), or ankle (Achilles tendinitis).
Tennis elbow is often idiopathic. Its cause and pathogenesis are unknown. [10] It likely involves tendinosis, a degeneration of the local tendon. [11] [10] It is thought this condition is caused by excessive use of the muscles of the back of the forearm, but this is not supported by evidence.
The flexor tendon is approximately 3 centimetres (1.2 in) long, crosses the medial aspect of the elbow, and runs parallel to the ulnar collateral ligament. [ 1 ] The injury is not acute inflammation , but rather is a chronic disorder resulting from overuse of a repetitive arm motion.
Enthesopathy can occur at the shoulder, elbow, wrist, carpus, hip, knee, ankle, tarsus, or heel bone, among other regions. Enthesopathies may take the form of spondyloarthropathies (joint diseases of the spine) such as ankylosing spondylitis, or psoriatic arthritis, plantar fasciitis, and Achilles tendinitis.
Ulnar neuropathy at the cubital tunnel is diagnosed based on characteristic symptoms and signs. Intermittent or static numbness in the small finger and ulnar half of the ring finger, weakness or atrophy of the first dorsal interosseous, positive Tinel sign over the ulnar nerve proximal to the cubital tunnel, and positive elbow flexion test (elicitation of paresthesia in the small and ring ...
[42] [43] The most useful single test for infraspinatous tendon tears is the drop sign (the examiner lifts the arm straight out from the body with the palm up, the person then needs to hold it there for 10 seconds) and the external rotation lag sign (with the arm by the side and the elbow bent to 90 degrees the person tries to rotate outwards ...
Inflammation to the tendons and muscles at these attachment points can lead to medial and/or lateral epicondylitis. This can occur through a range of factors that overuse the muscles that attach to the epicondyles, such as sports or job-related duties that increase the workload of the forearm musculature and place stress on the elbow.
The extensor carpi ulnaris extends the wrist, but when acting alone inclines the hand toward the ulnar side; by its continued action it extends the elbow-joint. The muscle is a minor extensor of the carpus in carnivores, but has become a flexor in ungulates. In this case it would be described as ulnaris lateralis.
