Abstract

The pisiform is a sesamoid bone that acts as one of the key medial stabilizers of the wrist. We present a case of a 35-year-old gentleman who presented with medial wrist pain following a fall while rollerblading. Radiographs and Magnetic resonance imaging (MRI) revealed a rare combination of an acute pisiform dislocation with associated triquetral fracture. Subsequently, he was successfully treated with excision of the pisiform. Pisiform dislocation is an uncommon injury and can easily be missed in an acute emergency presentation. Therefore, it is important to be aware of the characteristic imaging appearance to avoid a delay in diagnosis and treatment.
