Mechanism of the injury

These injuries are commonly caused by sporting accidents, often in ball games such as cricket, volleyball, basketball, etc.
Typically, hyperflexion of the finger causes an avulsion lesion of the central slip.
Often, in addition to hyperflexion, impact on the finger tips causes longitudinal compression forces on the middle phalanx towards the proximal phalanx, leading to an additional impaction fracture.
