Interphalangeal joint dislocations are common injuries in sport.
 
Volar dislocations at the PIP joint are less common than dorsal. Volar dislocations may be simple or rotatory. A rotatory-type dislocation involves injury to one of the collateral ligaments, which results in one of the proximal phalanx condyles passing between the central slip and lateral band.

Radiological evaluation post reduction of the central slip and collateral ligaments is required. 

Boutonnière deformity may result from a volar dislocation secondary to rupture of the central slip.  Appropriate evaluation for injury, splinting and follow up with a hand specialist is required.
