Extension Block Splinting for Dorsal P Ip Joint Fracture Dislocations

A 27 year old man falls on his hand at work. He notices an immediate deformity of his ring finger. Radiographs demonstrate a volar ip dislocation. What is the next best step? And the choices are, one, volar plate arthoblasty. Two, casto mobilization for six weeks. Three, dynamic distraction and external fixation. Four, extension block splinting and active range of motion. And five, extension block pinning.
