Common Causes and Who's at Risk
Distal phalanx fractures frequently occur due to direct blows or crush injuries, making them prevalent in sports and certain occupations. The middle finger is the most affected, with men being more prone to these injuries. In children, such fractures are often related to home accidents or sports, with boys experiencing them more than girls.
Understanding the Anatomy
The distal phalanx is the small bone at the tip of your fingers, crucial for nail growth and finger movement. Its structure includes tendons that control flexion and extension, making it susceptible to fractures if those tendons are damaged. The nail matrix is also a vital part, anchoring the nail and contributing to the complexity of injuries.
What Happens During an Injury?
When the distal phalanx is injured, significant soft tissue damage can occur, which might include nail bed injuries and severe pain. Such injuries may require urgent medical attention, especially if there's a risk of tendon dysfunction or nerve damage.
