Humerus is a forgiving bone.
You deformity is more in saggital plane..although it is not visible externally.. on x-ray it is quiet evident.
Callus formation is not great..in this plating, there should have been some callus fronton as the surgeon has used cortical screws, they do allow some micromotion.
Next Steps
I would have used a different implant than this one.
Health Tips
You are able to perform movements as the implant is bearing most of stresses. You might need bone grafting later, for permanent and long lasting solution.
