Surgeon wants to remove pin from non union scaphoid, have had 2 unsuccessful bone grafts,i'm not sure as from what i can see bone is still broken?

Non-union=still brkn: If they are calling it a non-union then that means the fracture has not healed so is technically still broken. To optimize bone healing, it is important to not smoke, limit alcohol, eat a healthy, balanced diet with sufficient protein and consider taking vit. C, D, mutli-mineral complex and I like to have patients add a collagen supplement.
