Broken humorous is not healing. What should I do?

Discuss w. ortho dr. You must be under an orthopedic dr.. Most common treatment for a non-displaced humerus fracture is a modified sling around neck & lower arm, allowing elbow to hang. Pinning may be required for fractures with displacement of brocken ends &/or non healing. Your orthopedist is best person to advise. However, always consider 2nd. Opinion if you, or spouse, think it necessary! good luck.
