Infectious tenosynovitis in 2.5% to 9.4% of all hand infections. Kanavel's cardinal signs are used to diagnose infectious tenosynovitis. They are: tenderness to touch along the flexor aspect of the finger, fusiform enlargement of the affected finger, the finger being held in slight flexion at rest, and severe pain with passive extension.
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).
The extensor tendon sheaths on the back of the wrist. De Quervain syndrome involves noninflammatory thickening of the tendons and the synovial sheaths that the tendons run through. The two tendons concerned are those of the extensor pollicis brevis and abductor pollicis longus muscles. These two muscles run side by side and function to bring ...
Medial injury of the flexor tendon is estimated to occur in 0.4% of the population. [1] It occurs most often in people ages 45 to 64, is more common in women than in men, and with 75% of cases in the dominant arm. [1] Risk factors for developing golfer's elbow include improper technique or lack of strength, endurance, or flexibility. [1]
For those with symptoms, the symptoms vary based on the phase of the disease. In the initial "formative phase" when the calcium deposits are being formed, people rarely experience any symptoms. [ 1 ] Those that do have symptoms tend to have intermittent shoulder pain, particularly during forward shoulder flexion (i.e. lifting the arm in front ...
Diagnosis is based on symptoms and examination. [8] Medical imaging is used mostly to plan surgery and is not needed for diagnosis. Treatment may include pain medication such as NSAIDs and specific exercises. [1] It is recommended that people who are unable to raise their arm above 90 degrees after two weeks should be further assessed. [9]
The patient needs to be in a seated position with the elbow flexed to 90°, forearm pronated (palm facing the ground), and the arm stabilized against the thorax. [2] [3] [4] The examiner places the stabilizing hand on the proximal portion of the humerus near the bicipital groove, and the resistance hand on the distal forearm and wrist. [1] [2]
The theory is that the radial nerve becomes irritated and/or inflamed from friction caused by compression by muscles in the forearm. [1]Some speculate that radial tunnel syndrome is a type of repetitive strain injury (RSI), but there is no detectable pathophysiology and even the existence of this disorder is questioned.
