Abstract
Isolated pisiform dislocation is a rare lesion with few cases described in the literature.
This type of lesion is typically observed in young males and can be easily overlooked
at first assessment. Isolated proximal dislocation is more common due to the action
of the flexor carpi ulnaris (FCU) muscle.
We present the case of a 19-year-old male patient with isolated distal pisiform dislocation
after wrist trauma. He underwent open reduction and internal fixation with Kirschner
wires with excellent functional outcomes.
Although there is no consensual therapeutic method, closed reduction is a first-line
treatment for acute presentations. Pisiform open reduction or excision may be performed
alternatively or after a failed closed reduction.
