Abstract

There are few reports of an isolated dislocation of the pisiform. An isolated dislocation of the pisiform without other injuries involving the carpal bones is particularly uncommon. This type of injury can be neglected in the acute period. We report a case of an isolated dislocation of the pisiform without a carpal bone injury in a young man treated primarily with a closed reduction, pinning and immobilization.

• 

  Fig. 1 Plain radiograph of the left wrist shows a dislocation of the pisiform with displacement.

• 

  Fig. 2 Three dimensional reconstructed computed tomography shows the displacement of the pisiform viewing from the radius.

• 

  Fig. 3 Axial view of computed tomography reveals widening of the pisotriquetral joint.

• 

  Fig. 4 Radiographs of the left wrist at the immediate postoperative period shows a well reduced pisifom fixed with Kirschner wire into the triquetrum.

• 

  Fig. 5 Radiographs taken 24 months after surgery shows a well reduced position of the pisiform.
