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 ...
A distal radius fracture, also known as wrist fracture, is a break of the part of the radius bone which is close to the wrist. [1] Symptoms include pain, bruising, and rapid-onset swelling. [1] The ulna bone may also be broken. [1] In younger people, these fractures typically occur during sports or a motor vehicle collision. [2]
Inflamed tendons of the hand. Tendinitis is disorder when tendons of the hands become inflamed. Tendons are thick fibrous cords that attach small muscles of the hand to bones. A Tendon is useful for generation of power to bend or extend the finger. When repetitive action is performed, tendons often get inflamed and present with pain and ...
The tendons most commonly replaced or supplemented by the palmaris longus tendon when ruptured are the long flexors of the fingers and the flexor pollicis longus tendon. [10] The palmaris longus muscle itself is a weak flexor, and provides no substantial flexing force that would inhibit movement in the wrist if its tendon were cut and moved ...
An illustration of wrist pain. Wrist pain or open wrist is a syndrome inhibiting use of a hand due to pain in anatomical structures of the wrist. [1] It most commonly results from an injury to a ligament. [1] The pain may be sharp from a traumatic injury or from chronic repetitive wrist activities. [1]
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.
Osteoarthritis commonly affects three main sites in the hand: the base of the thumb, where the thumb and wrist converge, known as the carpometacarpal (CMC) joint; the joint closest to the fingertip, referring to the distal interphalangeal joint (DIP); the middle joint of a finger, referring to the proximal interphalangeal joint (PIP). [5]
Anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a distal motor and sensory branch of the median nerve, classically with severe weakness of the pincer movement of the thumb and index finger, and can cause transient pain in the wrist (the terminal, sensory branch of the AIN innervates the bones of the carpal tunnel).
