The middle phalanges' (often those of the 2nd, 3rd and 5th digits of the hands) angel shape is caused by an abnormal development of the epiphysis, metaphysis, and diaphysis of said phalanges; the wings are formed by an abnormal dyaphysis, the angel's skirt is from a cone-shaped epiphysis, and the head is formed by an abnormal distal pseudoepophysis.
clubbing of distal phalanges Hirschberg test: Julius Hirschberg: ophthalmology: strabismus: corneal reflection centred (-) or not centred (+) on pupil Hoffmann's sign: Johann Hoffmann: neurology: corticospinal tract lesions: tapping distal phalanx of 3rd or 4th finger elicits flexion of same in thumb Hollenhorst plaque: Robert Hollenhorst ...
Hitchhiker's thumb, also known as distal hyperextensibility of the thumb, is the condition of having a thumb that has a distal phalange that bends backwards in an angle of 90°. This condition is benign (when isolated) and does not cause pain or affect the thumb with the trait negatively.
This deformity is caused by a widening of the epiphyseal plate of the fifth finger's distal phalange. [12] Another proposed cause involves the abnormal insertion of the flexor digitorum profundus in the volar area of the fifth finger's distal phalange. [13] It is thought to be an autosomal dominant trait with reduced penetrance. [14]
Gross clubbing – Thickening of the whole distal (end part of the) finger (resembling a drumstick) Hypertrophic osteoarthropathy – Shiny aspect and striation of the nail and skin; Schamroth's sign or Schamroth's window test (originally demonstrated by South African cardiologist Leo Schamroth on himself) [16] is a popular test for clubbing.
Limbs: carpal bone malsegmentation, hallux valgus, shortening of all distal phalanges of the fingers, shortening of all middle phalanges of the fingers Musculoskeletal system: cone-shaped epiphyses of the phalanges of the hand, cone-shaped epiphyses of the toes, craniosynostosis
Hypertrophic osteoarthropathy is a medical condition combining clubbing and periostitis of the small hand joints, especially the distal interphalangeal joints and the metacarpophalangeal joints. Distal expansion of the long bones as well as painful, swollen joints [ 3 ] and synovial villous proliferation are often seen.
