Mechanism of injury

Low impact trauma to the forefoot.


Imaging

Conventional radiographs of the foot. AP and lateral oblique views are sufficient for diagnosis and treatment.

Look for damage to the plantar plate by assessing sesamoid position on an AP radiograph. Check whether they are spread apart or not.


Clinical signs

The clinical picture includes swelling, ecchymosis, and pain with range of motion of the first MTP joint. The injury may present with or without deformity.
