Fractures of the distal phalanx are the most common fractures in the hand. Most frequently, the thumb, the middle finger, or somewhat less often, the index finger .
A broken thumb is a serious problem. It affects the ability to grasp items. A broken thumb can increase the risk of arthritis later in life.
Thumb distal phalanx tuft: oblique, transverse, or comminuted; tuft fractures usually result from crush injuries, and they are often comminuted and nearly always.
Distal phalanges are the most exposed phalanges and are, therefore, fractured more often than other hand fractures. The long finger is the most involved digit.
