Describe a fracture of the metacarpals
rapidly heal. May occur from severe crushing.
Boxer’s fracture of 5th metacarpal. Occurs from an unskilled punch.
Describe a fracture of the phalanges
distal phalange fracture occurs from getting fingers caught in car door – very painful due to highly developed sensation in fingers.
