GROSS ANATOMY

Detailed explanation-1: -A fracture of the neck of the fifth metacarpal, or boxer’s fracture, named for the classic mechanism of injury in which direct trauma is applied to a clenched fist, is the most common, representing 10% of all hand fractures.

Detailed explanation-2: -The most commonly affected bone is the fifth metatarsal, known as street fighter’s boxer fracture, which is connected to the fifth digit (small finger). Possible causes of fifth metacarpal fracture include punching with a clenched fist (most common cause), blunt force trauma, or crush injuries.

Detailed explanation-3: -The metacarpal neck and shaft are the most common sites for fractures of the second through fifth metacarpals, while the first (thumb) metacarpal is usually fractured at the base. A more detailed discussion of how fractures are categorized and how to describe radiographs of fractures is provided separately.

Detailed explanation-4: -Recovery times After a metacarpal fracture of the hand, most of the healing happens between 3 to 4 weeks. It’s normal to have aches and discomfort beyond this. This often happens when you try activities you haven’t done for a while. It’s also normal for the area to be more sensitive for several months after the injury.

Detailed explanation-5: -Metacarpal fractures can be treated non-surgically by applying a splint or cast over the fractured bone to promote natural healing. In severe cases, fractured bones are surgically fixed by using plates and screws.
