A fracture of the index finger is usually caused by a direct blow to the finger, such as when playing sports or by a fall onto the hand.
A fracture of the index finger can be diagnosed by physical examination, X-rays, or a CT scan. The physical examination will assess the degree of swelling, tenderness, and movement of the finger. X-rays will show the fracture and the extent of the damage. A CT scan will provide a more detailed image of the fracture and its location.
A fracture of the index finger can be confused with other conditions such as a sprain or tendon injury. These can be distinguished from a fracture by physical examination and imaging.
Treatment of a fracture of the index finger will depend on the extent of the damage. Mild fractures can be treated with immobilization, such as a splint or cast. Severe fractures may require surgery to repair the bone.
The prognosis for a fracture of the index finger is generally good. With proper treatment, the finger should heal in 4-6 weeks.
