See the list below:

  • The athlete typically sustains an axial loading blow to the finger that is combined with hyperextension.

  • Dorsal trauma produces a volar dislocation force with a concurrent central slip injury.

  • Radial- or ulnar-directed forces could produce a collateral ligament injury/lateral dislocation.

  • Inquire about potential dislocations that were reduced on the field. Careful attention to the mechanism of injury may help pinpoint the diagnosis.



See the list below:

  • Consider obtaining radiographs before physical examination of the affected finger to evaluate for potentially unstable fractures/dislocations.

  • Document the integrity of the neurovascular status of the affected finger as well as that of the entire hand.

  • Observe and palpate the affected finger, with attention to focal areas of tenderness and edema.

  • Assess tendon function and ROM of the affected finger, with particular attention to active extension. Loss of active extension indicates a central slip injury.

  • Assess the joint stability of the affected finger.

  • If pain of the affected finger precludes a definitive diagnosis, consider using metacarpal block anesthesia to examine the digit's tendon function and stability. [5]
