The bone is growing. She will always have a little bump on her upper arm that one can feel but cannot see. The doctors were pleased with the progress. I am amazed she didn't bump it (as Catherine takes nothing "slow"). But still -- the X-ray looks rough!
The crack line is less visible and there is a half moon of new growth starting on the top to straighten and elongate that area and "remodel" it how it is supposed to be.
