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.
Hypermobility, also known as double-jointedness, describes joints that stretch farther than normal. [2] For example, some hypermobile people can bend their thumbs backwards to their wrists and bend their knee joints backwards, put their leg behind the head or perform other contortionist "tricks".
Brachydactyly type D is a skeletal condition which exhibits a 'partial fusion or premature closing of the epiphysis with the distal phalanx of the thumb', according to Goodman et alia (1965). [6] J.K. Breithenbecher (1923) found that distal phalanges of short thumbs were one-half the length of full-length thumbs, while R.M. Stecher (1957 ...
In humans, the distal pads are wider than in other primates because the soft tissues of the finger tip are attached to a horseshoe-shaped edge on the underlying bone, and, in the grasping hand, the distal pads can therefore conform to uneven surfaces while pressure is distributed more evenly in the finger tips. The distal pad of the human thumb ...
Research shows that one in nine Americans have surgery in a given year. But just because it’s common doesn’t make going under the knife any less intimidating. Besides worrying about your ...
Brachyphalangy of the distal phalange of the thumb. This condition is caused by either fusion or early closure of the phalange's growth plate. One example is brachydactyly type D, which is caused by an early closure of the thumb's distal phalange, leading to a congenitally short thumb with a similarly short and wide thumb nail.
