In hands and feet the proximal phalanges are joined with metacarpals and metatarsals respectively. The phalanges have a central part, called the body, and two extremities; proximal extremity and distal extremity.
Phalanges Formula is expressed for the number of digits beginning from proximal. This formula is used to compare the number of phalanges in different animals. There are fourteen phalanges in each hand; three in long fingers and two in each thumb.
There are three injuries to phalanges generally which are; Open bone fracture, Close none fracture and Luxation. Serious injuries to proximal phalanges require surgery.
The function of phalanges is to provide stability to foot, dexterity to foot and to evenly disperse the body weight. As they are in toes of foot so they provide them with leverage and also enlarge the weight bearing area of foot.
The phalanges in fingers allow the hand to pick up things or generally allow the movements.
