Catherine's arm is continuing to heal. Every X-ray shows new bone growth.
This first X-ray shows her shoulder and upper arm. You can hardly see the fracture line anymore and along both sides of the bone you can see the shadow of the new bone being laid. You can also see the bump that will remain on her upper arm -- she can feel it, but it is not visible.
This x-ray is with her arm raised half way and the lower part shows just how much new bone there is. Pretty amazing how our bodies can heal themselves!
