As these are colloquial terms, texts and medical dictionaries do not universally agree on precise meanings. Various authorities state that a "boxer's fracture" means a break in specifically the second metacarpal bone or third metacarpal bone, [14] with "bar room fracture" being specific to the fourth metacarpal bone or fifth metacarpal bone. [15]
The neck of a metacarpal is a common location for a boxer's fracture, but all parts of the metacarpal bone (including head, body and base) are susceptible to fracture. During their lifetime, 2.5% of individuals will experience at least one metacarpal fracture. Bennett's fracture (base of the thumb) is the most common. [4]
The third metacarpal bone (metacarpal bone of the middle finger) is a little smaller than the second.. The dorsal aspect of its base presents on its radial side a pyramidal eminence, the styloid process, which extends upward behind the capitate; immediately distal to this is a rough surface for the attachment of the extensor carpi radialis brevis muscle.

The facet on the ulnar side articulates with the third metacarpal. The extensor carpi radialis longus muscle is inserted on the dorsal surface and the flexor carpi radialis muscle on the volar surface of the base. [1] The shaft gives origin to the first palmar interosseus and the first and second dorsal interossei.
The third metatarsal bone is a long bone in the foot. It is the second longest metatarsal, the longest being the second metatarsal. The third metatarsal is analogous to the third metacarpal bone in the hand [1] Like the four other metatarsal bones, it can be divided into three part: base, body and head.
Rolando fracture – a comminuted intra-articular fracture through the base of the first metacarpal bone; Bennett's fracture – a fracture of the base of the first metacarpal bone which extends into the carpometacarpal (CMC) joint [15] Boxer's fracture – a fracture at the neck of a metacarpal; Broken finger – a fracture of the carpal ...
It articulates with the third metacarpal bone (the middle finger) and forms the third carpometacarpal joint. The capitate bone is the largest of the carpal bones in the human hand . It presents, above, a rounded portion or head, which is received into the concavity formed by the scaphoid and lunate bones ; a constricted portion or neck; and ...
