Fracture of the little finger can occur due to direct trauma, such as a fall or a blow to the finger, or due to indirect trauma, such as overstretching or twisting the finger in an awkward position.
The diagnosis is usually made based on a physical examination of the finger. X-rays may be required to confirm the diagnosis and to assess the severity of the fracture.
The differential diagnosis for a fracture of the little finger includes tendon and ligament injuries, dislocated joints, and soft-tissue problems such as sprains and strains.
Treatment usually involves immobilizing the finger with a splint or cast to allow the fracture to heal. Surgery may be required if the fracture is severe or the bones have shifted out of alignment.
The prognosis for a fracture of the little finger is generally good. Most fractures heal without complications and the finger regains full function.
