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]
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]
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).
Diagnosis is based on symptoms and clinical signs that are discrete and characteristic. For example, the extension of the elbow and flexion of the wrist causes outer elbow pain. The physical examination usually reveals marked tenderness at the origin of the extensor carpi radialis brevis muscle from the lateral epicondyle (extensor carpi ...
Elbow pain generally refers to discomfort in the joint between the upper arm and forearm. Elbow pain is a common complaint in both the emergency department and in primary care offices. The CDC estimated that 1.15 million people visited an emergency room for elbow or forearm-related injuries in 2020. [1]
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 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 ...
Lateral elbow pain can be caused by various pathologies of the common extensor tendon. [3] Overuse injuries can lead to inflammation. [4] [5] Tennis elbow is a common issue with the common extensor tendon. [6] [4] [7]
