Final Answer:
Treatment for a mallet fracture, caused by a forced flexion injury of the DIP joint resulting in a small bone fragment at the dorsal surface of the proximal distal phalanx, may involve splinting the DIP joint in extension or, in some cases, surgical intervention.
Step-by-step explanation:
A mallet fracture, also known as a baseball or drop finger, occurs when the extensor tendon is disrupted, leading to a forced flexion injury at the distal interphalangeal (DIP) joint. Treatment aims to address the deformity caused by the avulsion of a small bone fragment at the dorsal surface of the proximal distal phalanx.
Non-surgical management often involves splinting the DIP joint in extension, maintaining it in a straightened position to allow the extensor tendon to heal. However, some cases, particularly those with large or displaced fractures, may require surgical intervention to reposition and stabilize the fractured bone fragment.
