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 ...
Delayed onset muscle soreness (DOMS) is the pain and stiffness felt in muscles after unaccustomed or strenuous exercise. The soreness is felt most strongly 24 to 72 hours after the exercise.
The Achilles tendon is wider than normal, further suggesting inflammation. Achilles tendinitis is usually diagnosed from a medical history, and physical examination of the tendon. Projectional radiography shows calcification deposits within the tendon at its calcaneal insertion in approximately 60 percent of cases. [17]
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).
An Achilles tendon rupture is estimated to occur in a little over 1 per 10,000 people per year. Males are also over 2 times more likely to develop an Achilles tendon rupture as opposed to women. Achilles tendon rupture tends to occur most frequently between the ages of 25-40 and over 60 years of age.
Patellar tendinitis is an overuse injury from repetitive overloading or repetitive stress of the patellar tendon of the knee leading to microtears and inflammation that do not have time to heal before the next use. Patellar tendonitis is common in athletes who participate in activities that include a lot of jumping, changing directions, or running.
Intrinsic factors refer to injury mechanisms that occur within the rotator cuff itself. The principal is a degenerative-microtrauma model, which supposes that age-related tendon damage compounded by chronic microtrauma results in partial tendon tears that then develop into full rotator cuff tears.
