Worth a Second Look: Report of a Rare Traumatic Pisiform Fracture Following a Bicycle Fall.

Fractures of the pisiform bone are difficult to diagnose due to the often unsuspicious conventional X-ray images and nonspecific clinical presentation. The following case presents a 29-year-old patient who suffered a bicycle fall onto their right hand and experienced prolonged symptoms despite the initial lack of evidence of a fracture. The fractured pisiform bone, which was eventually detected in a CT scan, was successfully treated with a 4-week period of cast immobilization. The existing conservative and surgical treatment options of a pisiform bone fracture are discussed.
