People with severe involvement often show lumps on the back of their finger joints (called "Garrod's pads", "knuckle pads", or "dorsal Dupuytren nodules"), and lumps in the arch of the feet (plantar fibromatosis or Ledderhose disease). [17] In severe cases, the area where the palm meets the wrist may develop lumps.
A hand imitating an ulnar claw. The metacarpophalangeal joints of the 4th and 5th fingers are extended and the Interphalangeal joints of the same fingers are flexed.. An ulnar claw, also known as claw hand or ‘Spinster’s Claw’, is a deformity or an abnormal attitude of the hand that develops due to ulnar nerve damage causing paralysis of the lumbricals.
Weakness in flexion of the hand at the wrist, loss of flexion of ulnar half of digits, or the 4th and 5th digits, loss of ability to cross the digits of the hand. (Note: Motor deficit is absent or very minor in cubital tunnel syndrome as the ulnar nerve is compressed in the cubital tunnel, rather than transected.)
The proper palmar digital nerves of the ulnar nerve are nerves of the hand.. The superficial branch of the ulnar nerve divides into a proper palmar digital nerve, which supplies the medial side of the fifth digit and a common palmar digital nerve which divides into two proper palmar digital nerves that supply the adjacent sides of the fourth and fifth digits.
The word "pinkie" is derived from the Dutch word pink, meaning "little finger".. The earliest recorded use of the term "pinkie" is from Scotland in 1808. [1] The term (sometimes spelled "pinky") is common in Scottish English [2] and American English, [3] and is also used extensively in other Commonwealth countries such as New Zealand, Canada, and Australia.
Wartenberg's sign is a neurological sign consisting of involuntary abduction of the fifth (little) finger, caused by unopposed action of the extensor digiti minimi. [ 1 ] [ 2 ] This commonly results from weakness of some of the ulnar nerve innervated intrinsic hand muscles -in particular the palmar interosseous muscle to the little finger ...
In human anatomy, the abductor digiti minimi (abductor minimi digiti, abductor digiti quinti, ADM) is a skeletal muscle situated on the ulnar border of the palm of the hand. It forms the ulnar border of the palm and its spindle-like shape defines the hypothenar eminence of the palm together with the skin, connective tissue, and fat surrounding it.
Medial border of 5th metacarpal (in hand, 3rd digit is orientation of mid-line) Artery: Ulnar artery: Nerve: Deep branch of ulnar nerve (C8 and T1) Actions: Draws 5th metacarpal anteriorly and rotates it, bringing little finger (5th digit) into opposition with thumb: Identifiers; Latin: musculus opponens digiti minimi (Old: opponens quinti ...
