The ulnar styloid process is a bony protrusion at the end of the ulna, close to the hand. It has a vital role in the strength and flexibility of the wrist and forearm. If there is damage in this area, it is called as an ulnar styloid fracture.
What are the signs?
The distinctive sign of an ulnar styloid fracture is immediate pain. This injury typically occurs along with a radius fracture. Once this occurs, there is pain in the interior side of the wrist.
Other signs that might be present include:
- Swelling
- Tenderness
- Bruising
In serious cases, the affected wrist and hand might hang at a different angle than normal.
What are the causes?
Most cases of wrist and hand fractures are brought about by attempting to break a fall with extended arms.
Other usual causes of an ulnar styloid fracture include:
- Hard falls
- Vehicular accidents
- Sports injuries
Additionally, osteoporosis increases the risk for the fracture.
Management of an ulnar styloid fracture
The treatment is aimed on allowing the bones to heal back into their original position. This is done with or without surgery.
Conservative treatment
For a mild ulnar styloid fracture, it often requires a basic wrist cast. In some instances, the doctor might suggest realigning of the bones before a cast is placed.
Surgical treatment
For serious breaks, including those that involve other nearby bones, surgery is suggested, usually open reduction.
The doctor will create an incision close to the break and utilize the opening to reset the affected bone. A severe break might require the placement of pins or screws to secure the bones in place as they heal.
After open reduction, a cast is placed that is usually made from fiberglass or plaster.
