Are Metacarpal Fractures More Common Than You Think?
Published: Apr 06, 2024
Metacarpal fractures make up a significant portion of hand injuries, often resulting from direct trauma. Understanding their classification and management can help in effective treatment.
Understanding Metacarpal Fractures
Metacarpal fractures are common hand injuries that occur in the bones of your fingers. They are typically caused by direct trauma or repetitive stress, particularly in athletes. These fractures are classified based on their location on the bone and the type of fracture, such as transverse or spiral.
Anatomy of Metacarpals
The metacarpals are long bones in the hand that connect the wrist to the fingers and are essential for hand movement. They are reinforced by ligaments and muscles, providing stability and the ability to perform tasks like gripping. Different metacarpals have varying degrees of mobility, with the thumb being the most flexible.
Examining a Suspected Fracture
When assessing a potential metacarpal fracture, doctors look for visible deformities, skin damage, and check the alignment of the bones. It is important to also assess nerve and blood vessel function to ensure that no further complications arise from the injury.
