Pisiform Fractures: The Hidden Wrist Injury
Understanding Pisiform Fractures
Pisiform fractures are a rare type of wrist injury that can cause significant pain and dysfunction. Understanding this condition can help in recognizing symptoms and seeking appropriate treatment.
Contents
What is a Pisiform Fracture?
A pisiform fracture is a break in one of the small bones in your wrist known as the pisiform. This bone is a sesamoid, meaning it is embedded within a tendon, specifically the flexor carpi ulnaris tendon. Pisiform fractures are uncommon and account for only 1.7% of all carpal fractures, typically resulting from falls or direct blows to the hand.
Symptoms to Watch For
The most common symptom of a pisiform fracture is localized pain and swelling on the palmar side of the wrist. Additionally, if the ulnar nerve is affected, you may experience numbness or weakness in your little and ring fingers. Pain typically increases with wrist movement, especially when bending the wrist or moving it sideways.
Diagnosing Pisiform Fractures
Diagnosing a pisiform fracture often begins with an X-ray, although these fractures can be difficult to see. If a fracture is suspected but not visible, doctors may use a CT scan or MRI to confirm the diagnosis. These imaging methods provide a clearer view of both the bone and surrounding soft tissues.
