What type of hand fractures make up 50-60% of all hand fractures?

  1. Phalangeal fractures

  2. Metacarpal fractures

  3. Scaphoid fractures

  4. Proximal phalanx fractures

The correct answer is: Metacarpal fractures

Metacarpal fractures account for a significant proportion of hand fractures, making up 50-60% of all cases. This high prevalence can be attributed to their anatomical location, as the metacarpals are the long bones in the hand that connect the wrist to the fingers. They are often subjected to high forces from direct trauma, such as punching a hard object, which is the most common cause of such fractures. In considering the other options, phalangeal fractures, while common, do not reach the same prevalence as metacarpal fractures. Scaphoid fractures, although frequently discussed in the context of wrist injuries, are relatively less common overall compared to metacarpal fractures. Proximal phalanx fractures do occur, but they also do not reach the same incidence level as those involving the metacarpals. The emphasis on metacarpal fractures reflects their clinical significance in hand injuries, making awareness of these fractures vital for effective assessment and treatment in hand therapy practices.
