Metacarpus

 

the part of the superior (anterior) pentadactyl extremity of vertebrates that is located between the carpus and the distal phalanges of the fingers. In man, the metacarpus is made up of five metacarpal bones, which are attached to the muscles of the palm. The hypothenal muscles of the thumb and the little finger are the largest muscles of the palm. The tendons of the antebrachial muscles, which set the fingers in motion, pass along the metacarpal bones; blood vessels and motor and sensory nerves are also located here. On the palm side, the metacarpal skin is thick and hairless and the fold markings are individuated. On the dorsal side, the skin is thinner and often covered with short hairs. Tendovaginitis develops with inflammatory diseases of the sheaths of the tendons. Fractures of the metacarpal bones require apposition and immobilization for a period up to 1—1½ months.

Closed, easily reduced fractures of the metacarpus are managed with coaptation using a reinforced splint (curved-edge splint) and figure-of-8 bandage, especially if the minor metacarpal bone is intact or the fracture is too proximal for fixation hardware.
described a positive correlation between the grip strength and the circumference of the metacarpus, wrist, and upper arm [21].
In addition, compared with the proximal dorsum of the metacarpus, there is more abundant soft tissue coverage around the lateral side of the metacarpal neck and fixation of both the fourth and the fifth metacarpal fractures can be undertaken with only one incision.
Radical amputations of the upper limbs at the level of the forearm, the wrist and the metacarpus cause rupture of all the anatomical structures, i.e.
Comparing the forelimbs of CCB-1 with those of Dollo's goniopholidid, one of the most complete goniopholidid skeletons in existence, differences in robustness can also be observed; the carpus, metacarpus and phalanges of CCB-1 are much shorter and more robust than in Dollo's goniopholidid.
It is probable that the skeletal development in distal elements of quail wing happens around the end of the first week with special mention of development in metacarpus, and digits area.
The metacarpus is essential for the anatomical structure of the hand and for the motion of the fingers.
Length of head, toe, femur, tibia, metacarpus, and mouth opening were highest loading variables on each component, respectively.
