What is Scaphoid Non Union?
Scaphoid Non Union is a condition where a fractured scaphoid bone in the wrist fails to heal properly over time. The scaphoid is an important wrist bone that helps maintain wrist stability and movement.
If left untreated, Scaphoid Non Union can lead to chronic wrist pain, weakness, stiffness, and arthritis.
Symptoms of Scaphoid Non Union
Common signs and symptoms include:
- Persistent wrist pain
- Tenderness near the thumb side of the wrist
- Reduced wrist movement
- Weak grip strength
- Swelling around the wrist
- Pain during lifting or gripping activities
Causes & Risk Factors
Scaphoid Non Union usually develops when a scaphoid fracture does not heal completely.
- Delayed diagnosis of scaphoid fracture
- Inadequate immobilization after injury
- Poor blood supply to the scaphoid bone
- Repeated wrist stress or trauma
- Smoking and poor bone healing
Diagnosis
Proper diagnosis helps evaluate bone healing and wrist stability for effective treatment planning.
- Detailed wrist examination
- X-rays to assess bone healing
- CT scan for detailed fracture evaluation
- MRI to check blood supply if required
Treatment for Scaphoid Non Union
Treatment depends on the severity and duration of the condition.
- Wrist immobilization in selected cases
- Bone grafting procedures
- Surgical fixation using screws or pins
- Wrist arthroscopy if required
- Rehabilitation and physiotherapy
Early treatment improves healing, restores wrist function, and reduces the risk of arthritis.
Benefits of Early Treatment
- Better bone healing outcomes
- Reduced wrist pain and stiffness
- Improved wrist strength and movement
- Prevention of wrist arthritis
Prevention Tips
You can reduce the risk of Scaphoid Non Union by:
- Seeking early treatment after wrist injuries
- Following proper immobilization instructions
- Avoiding excessive wrist strain during healing
- Maintaining good bone health
- Avoiding smoking for better bone healing
