Fractures and dislocations of the hand and fingers are common injuries. Conservative treatment is sufficient in most cases. Reduction and application of a cast comprise the first-line treatment also in dislocated fractures because complications are more frequent with surgical treatment. The appropriate mode of treatment can thus not be decided on the basis of the primary x-ray findings alone, before reduction is performed. The position of immobilization is crucial for the maximum restoration of function in the hand: interphalangeal (IP) joints are immobilized in a straight position and metacarpophalangeal (MCP) joints in a flexion of 70-90°. A mallet finger may be caused by an injury or may be of degenerative origin. It requires long, continuous splinting.
