Mallet Finger
Symptoms and Signs of Mallet Finger
The finger is usually painful and may be swollen and bruised immediately after the injury. Occasionally, blood collects under the nail (called). The affected dorsal interphalangeal (DIP) joint rests in a more flexed position than the other DIP joints and cannot be actively straightened but can easily be passively straightened, usually with minimal pain.
