What Causes Bone To Get Separated Completely After Healing From Fracture?

I fractured my scapoid 3 months ago and had a screw inserted a week after the accident (no graft required because it was a fresh brake) I had an xray 2 months later and there was still a visable crack through the bone but there was calcification in some parts of the brake, so it was clearly healing. However 6 weeks later, another xray showed that the bone had seperated completly again.....why would this happen?

Hi,

This can happen because the vascularization of the scaphoid is disrupted when fractured. Thus, the proximal pole of the scaphoid bone will get devascularized, and devascularized bone is not prone to healing. This condition is typical of the scaphoid bone, and there are several ways to treat scaphoid non-union.

Take care. Hope I have answered your question. Let me know if I can assist you further.
