Trigger finger, also known as stenosing tenosynovitis, is a disorder characterized by catching or locking of the involved finger in full or near full flexion, typically with force. [2] There may be tenderness in the palm of the hand near the last skin crease (distal palmar crease ). [ 3 ]
Finkelstein's test was described by Harry Finkelstein (1865–1939), an American surgeon, in 1930. [5]A similar test was previously described by Eichhoff, in which the thumb is placed in the palm of the hand and held with the fingers, and the hand is then ulnar deviated (see images), causing intense pain over the radial styloid which disappears if the thumb is released.
Treatment for de Quervain tenosynovitis focuses on reducing inflammation, restoring movement in the thumb, and maintaining the range of motion of the wrist, thumb, and fingers. [6] Symptomatic alleviation (palliative treatment) is provided mainly by splinting the thumb and wrist. Pain medications such as NSAIDs can also be considered.
The conclusion reached is that the pathophysiology of tennis elbow is due to an initial microscopic tear from a sprain/strain. This initial injury is aggravated at night by pressure on the sprain which delays healing. In other words, tennis elbow is neither a tendonitis nor a tendinosis, but more like a pressure sore. If the pressure is removed ...
Infectious tenosynovitis is the infection of closed synovial sheaths in the flexor tendons of the fingers. It is usually caused by trauma, but bacteria can spread from other sites of the body. Although tenosynovitis usually affects the flexor tendon of the fingers, the disease can also affect the extensor tendons occasionally. [5]
A common injury to the extensor carpi ulnaris is tennis elbow. This injury occurs in people who participate in activities requiring repetitive arm, elbow, and wrist, especially when they are tightly gripping an object. Some symptoms of an extensor carpi ulnaris injury include pain when shaking hands or when squeezing/gripping an object.
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).
Variations of the fifth extensor compartment, which the extensor digiti minimi runs through, may cause tenosynovitis and can limit the use of the extensor digiti minimi. The extensor digiti minimi can also be bifurcated, which means split, at many different points in the muscle.
