Differential Diagnosis for Adulation Fracture Finger
Single Most Likely Diagnosis
- Mallet Finger: This condition is the most likely diagnosis for an adulation fracture of the finger, which typically occurs when the extensor tendon is injured, often due to a sudden, forceful flexion of the distal interphalangeal joint, such as when trying to catch a ball.
Other Likely Diagnoses
- Boutonniere Deformity: Although less common than mallet finger, boutonniere deformity can result from a similar mechanism of injury affecting the proximal interphalangeal joint, leading to flexion contracture.
- Fracture of the Distal Phalanx: A fracture at the base of the distal phalanx can mimic the symptoms of an adulation fracture, especially if it involves the articular surface.
Do Not Miss Diagnoses
- Open Fracture: Any fracture that communicates with the external environment through a wound is considered an open fracture. This condition requires immediate medical attention due to the high risk of infection.
- Neurovascular Injury: Damage to the nerves or blood vessels in the finger can lead to serious complications, including loss of sensation, movement, or even the finger itself if not promptly addressed.
Rare Diagnoses
- Intra-articular Fracture with Displacement: While not the most common presentation, an intra-articular fracture of the distal interphalangeal joint with significant displacement can occur and may require surgical intervention.
- Seymour Fracture: A rare type of fracture involving the base of the distal phalanx in children, which can be complicated by the presence of an open growth plate and potential for infection if the fracture is open.
