Metacarpal fracture is a condition characterized by the breakage or dislocation of the long hand bones called metacarpals that form the skeleton of the palm. Metacarpal fractures can damage associated soft tissues such as cartilage, ligament, tendons, joint capsule, as well as adjoining nerves.
Each finger is made up of 3 bones called phalanges that are separated by 2 joints. The thumb has 2 phalanges that are separated by one joint. An injury to the fingers can cause a fracture of one of its phalanges.
