Brachydactyly type D, also known as short thumb, [3] [1] stub thumb, [5] [6] or clubbed thumb, [5] [6] is a genetic trait clinically recognised by a thumb being relatively short and round with an accompanying wider nail bed. The distal phalanx of affected thumbs is approximately two-thirds the length of full-length thumbs.
A broken finger or finger fracture is a common type of bone fracture, affecting a finger. [1] Symptoms may include pain, swelling, tenderness, bruising, deformity and reduced ability to move the finger. [2] Although most finger fractures are easy to treat, failing to deal with a fracture appropriately may result in long-term pain and disability ...
This type is indicated when one thumb is larger proximally and the other thumb has a larger distal component. (The procedure is initially described as a way to lengthen amputated digits.) The goal is to create a functional thumb by combining less-hypoplastic components.
In most cases, children born with symbrachydactyly are able to adapt to their physical limitations and experience a fully functional life with no treatment. Most children with this condition can use their hands well enough to do all the usual things children do. [3] Possible treatment includes surgery or a routine of regularly stretching the ...
intra-articular fracture of base of Thumb metacarpal: axial load along metacarpal in a partially flexed thumb: Bennett's fracture at Who Named It? Bosworth fracture: David M. Bosworth: fracture of distal fibula with posterior dislocation of the proximal fibula behind the tibia: severe external rotation of the foot "Bosworth fracture dislocation".
Symptoms of Bennett fracture are instability of the CMC joint of the thumb, accompanied by pain and weakness of the pinch grasp. Characteristic signs include pain, swelling, and ecchymosis around the base of the thumb and thenar eminence, and especially over the CMC joint of the thumb. Physical examination demonstrates instability of the CMC ...
Arrows show the vestigial structure called Darwin's tubercle. In the context of human evolution, vestigiality involves those traits occurring in humans that have lost all or most of their original function through evolution. Although structures called vestigial often appear functionless, they may retain lesser functions or develop minor new ones.
Brachydactyly type D. "Stub Thumb" Referred to inaccurately as "clubbed thumbs". [11] Most common form of brachydactyly. It shortens the final bone in the thumbs and does not affect the fingers at all. [9] Type E, BDE: 113300: HOXD13: 2q31-q32: Brachydactyly type E. This is the rarest form of brachydactyly.
