Anatomy
There are approximately 29 bones in the hand and wrist together, 5 of which are called the metacarpals. The metacarpals lie in the region between the proximal phalange bones and the carpal bones. Boxers fracture generally occurs in the 4th and/or 5th metacarpal of the hand. More specifically, the fracture happens in the neck region in the distal end of the metacarpal. The bone itself is located between the joints called the metacarpophalangeal joint and the carpometacarpal joint. The fracture occurs just below the head of the metacarpal which is the neck region of the metacarpal. The neck is the most susceptible and prone to breaks because it is the most fragile part of the metacarpal.

Famous quotes containing the word anatomy:
“I love to see, when leaves depart,
The clear anatomy arrive,”
—Roy Campbell (1902–1957)
“Man is a shrewd inventor, and is ever taking the hint of a new machine from his own structure, adapting some secret of his own anatomy in iron, wood, and leather, to some required function in the work of the world.”
—Ralph Waldo Emerson (1803–1882)
“But a man must keep an eye on his servants, if he would not have them rule him. Man is a shrewd inventor, and is ever taking the hint of a new machine from his own structure, adapting some secret of his own anatomy in iron, wood, and leather, to some required function in the work of the world. But it is found that the machine unmans the user. What he gains in making cloth, he loses in general power.”
—Ralph Waldo Emerson (1803–1882)
