Double Dislocation of the Interphalangeal Joints of the Little Finger.

High-energy traumas may lead to the dislocation of joints with or without fractures. However, simultaneous double dislocation of the proximal and distal interphalangeal joints (PIP and DIP) in fingers shows up rarely. Although it can be inferred as simultaneous dislocation occurring during the same trauma, consecutive events should be taken into consideration. A 29-year-old, right-hand dominant male patient presented to the emergency room with a left little finger deformity after being hit by a ball while playing football. Despite the inability to move the little afteruent to this hyperextension injury, there was mild swelling, ecchymosis, and pain with no trace of laceration or neurovascular injury. PIP and DIP joint dislocations of the left-hand little finger with distal phalanx proximal fracture were detected on the radiograph indicating a stepladder deformity. Closed reduction was achieved by longitudinal traction and applying pressure over the base of the dislocated digit. Afterward, an aluminum finger splint was applied to the little finger in the functional position to prevent further damage. Re-evaluation radiographs revealed a successful reduction of both joints. Immobilization via an aluminum finger splint was recommended for three weeks. Subsequently, range of motion exercises and rehabilitation were started. Three-month follow-up revealed an almost full range of motion in both PIP and DIP joints without stiffness and pain. Although double dislocation seems to present with more painful and swollen fingers than single dislocations, it can also present with mild pain and swelling, as in this case. The little finger is easily exposed to traumas due to the lack of surrounding tissue. Therefore, double dislocation is mostly seen in the little finger. This case report briefly illustrates a rare incidence of double dislocation involving both the PIP and DIP joints of the little finger. Normal range of motion of both joints was reached by early reduction followed by timely rehabilitation.
