Fractures of scaphoid can occur either with direct axial compression or with hyperextension of the wrist, such as a fall on the palm on an outstretched hand. Using the Herbert classification system, there are three main types of scaphoid fractures. 10%-20% of fractures are at the proximal pole, 60%-80% are at the waist (middle), and the ...
The muscles of the thumb are nine skeletal muscles located in the hand and forearm. The muscles allow for flexion , extension , adduction , abduction and opposition of the thumb . The muscles acting on the thumb can be divided into two groups: The extrinsic hand muscles, with their muscle bellies located in the forearm, and the intrinsic hand ...
The latter involves compression at the wrist of the superficial sensory branch of the radial nerve which does not innervate hand muscles. [citation needed] Robert Wartenberg (1887-1956) was a neurologist born in Belarus who worked in Germany until 1935 when he emigrated to the United States. He was widely published and described a number of ...
Abductor pollicis brevis abducts the thumb. This muscle is the most superficial of the thenar group. Flexor pollicis brevis, which lies next to the abductor, will flex the thumb, curling it up in the palm. (The flexor pollicis longus, which is inserted into the distal phalanx of the thumb, is not considered part of the thenar eminence.)
Osteoarthritis is most common at the base of thumb and is usually treated with pain pills, splinting or steroid injections. [2] Carpal tunnel syndrome is a common disorder of the hand. This disorder results from compression of the median nerve in the wrist.
Untreated carpal tunnel syndrome, showing shrinkage (atrophy) of the muscles at the base of the thumb: Specialty: Orthopedic surgery, plastic surgery, neurology: Symptoms: Numbness, tingling in the thumb, index, middle finger, and half of ring finger. [1] [2] Causes: Compression of the median nerve at the carpal tunnel [1] Risk factors ...
The flexor pollicis longus (/ ˈ f l ɛ k s ər ˈ p ɒ l ɪ s ɪ s ˈ l ɒ ŋ ɡ ə s /; FPL, Latin flexor, bender; pollicis, of the thumb; longus, long) is a muscle in the forearm and hand that flexes the thumb. It lies in the same plane as the flexor digitorum profundus. This muscle is unique to humans, being either rudimentary or absent in ...
Lack of ability to abduct and oppose the thumb due to paralysis of the thenar muscles. This is called "ape-hand deformity". [3] Sensory loss in the thumbs, index fingers, long fingers, and the radial aspect of the ring fingers. Weakness in forearm pronation and wrist and finger flexion [2]
