Dupuytren's contracture (also called Dupuytren's disease, Morbus Dupuytren, Palmar fibromatosis and historically as Viking disease or Celtic hand) is a condition in which one or more fingers become permanently bent in a flexed position. [2]
The thenar eminence is the mound formed at the base of the thumb on the palm of the hand by the intrinsic group of muscles of the thumb. [1] The skin overlying this region is the area stimulated when trying to elicit a palmomental reflex. The word thenar comes from Ancient Greek θέναρ (thenar) 'palm of the hand'. [2]
The muscle contracts and fails to relax again, becoming hard or stiff, the muscle may swell up, and although temporary, it is longer lasting and generally more painful than muscle cramps. [ 4 ] [ 5 ] These contractures are different from cramps, because they are not elicited by the nerve, but by intrinsic mechanisms in the muscle itself and are ...
Symptoms of carpal tunnel syndrome include tingling sensations and muscle weakness in the palm and lateral side of the hand and palm. It is possible that the syndrome may extend and radiate up the nerve causing pain to the arm and shoulder. [4] Carpal tunnel syndrome may be treated surgically.
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 following tendon deviations can induce congenital clasped thumb: The flexor tendons are too short (the thumb is drawn into the palm) The abductor tendons are hypoplastic or absent; The extensor tendons are hypoplastic or absent; Furthermore, a tight thumb web space (the area between thumb and index finger) can contribute to congenital ...
A person with idiopathic carpal tunnel syndrome will not have any sensory loss over the thenar eminence (bulge of muscles in the palm of hand and at the base of the thumb). This is because the palmar branch of the median nerve, which innervates that area of the palm, separates from the median nerve and passes over the carpal tunnel. [39]
It is most common in the thumb and ring finger. The triggering more often occurs while gripping an object firmly or during sleep when the palm of the subject’s hand remains closed for an extended period of time, presumably because the enlargement of the tendon is maximum when the finger is not being used.
