What is the scaphoid bone?
The scaphoid is a bone located in the center of the wrist. It is shaped like a boat with one side larger than the other. The function of this irregularly shaped bone is to provide structural support, maintain stability, and serve as an insertion site for many tendons. It is commonly injured by falling on an outstretched hand.
What are some common signs/symptoms associated with this injury?
Common symptoms include tenderness upon palpation at the thumb side of the wrist, pain on wrist movement, and functional limitations in daily activities, and swelling or pain near the base of the thumb.
How are scaphoid fractures treated?
The goal of treatment is to restore normal anatomy. Advanced imaging, such as CT or MRI, are often needed because surgery may be required for scaphoid fractures if they are off by even a millimeter or two. Treatment options include casting, internal fixation (screws), or open reduction/internal fixation (ORIF).
What follow-up care will be necessary?
Depending on the type of procedure used for repair, between 1 week to 8 weeks of immobilization may be required. Afterward, our occupational/hand therapist will instruct you in an exercise program that emphasizes the motion of the wrist and thumb.
How long before an injured worker can return to work?
The time off from work varies depending on activity levels and occupation. If surgery is needed, physical therapy would begin after about 4-6 weeks and it is recommended that you avoid strenuous activities during this time period.
What problems can occur if scaphoid fractures are not treated?
If not treated properly, the fragments may not heal. This is called a non-union. This can cause pain and potentially restrict motion. Most people with a scaphoid non-union will develop wrist arthritis early in life. Treatment of arthritis may require fusions of the wrist.
With proper treatment, what are the expected outcomes of a scaphoid fracture?
The majority of people with this injury have excellent functional outcomes with nearly full range of motion and strength restored.
