A broken finger or finger fracture is a common type of bone fracture, affecting a finger. [1] Symptoms may include pain, swelling, tenderness, bruising, deformity and reduced ability to move the finger. [2] Although most finger fractures are easy to treat, failing to deal with a fracture appropriately may result in long-term pain and disability ...
In human anatomy, the metacarpal bones or metacarpus, also known as the "palm bones", are the appendicular bones that form the intermediate part of the hand between the phalanges and the carpal bones (wrist bones), which articulate with the forearm. The metacarpal bones are homologous to the metatarsal bones in the foot.

Fractures of the fingers occur when the finger or hands hit a solid object. Fractures are most common at the base of the little finger (boxer's fracture). Nerve injuries occur as a result of trauma, compression or over-stretching. Nerves send impulses to the brain about sensation and also play an important role in finger movement.
In terms of anatomy location, fractures of finger phalanges are the most common one at the rate of 14 per 100,000 people per year in the general population, followed by fracture of tibia at 3.4 per 100,000 population per year, and distal radius fracture at 2.4 per 100,000 population per year. [5]
When a fracture occurs, there may be a snapping or popping sensation. There will be swelling of the hand along with discoloration or bruising in the affected area. Abrasions or lacerations of the hand are also likely to occur. The respective finger may be misaligned, and movement of that finger may be limited and painful. [citation needed]
A fracture of the fourth and/or fifth metacarpal bones transverse neck secondary due to axial loading is known as a boxer's fracture. [1] [[ Boxer%27s_fracture#{{{section}}}| contradictory ]] ] The fifth metacarpal bone is the most common bone to be injured when throwing a punch.
