I broke my humerous in 2002 and got a plate implant in 2003 but the bone hasn't healed and the plate is trying to come out with pus, what can i do?

Seek attention: Draining pus, a non healing bone and a moving plate are signs of an infected nonunion. If this s the case it must be treated. Range of treatments include plate removal placement of antibiotics. Replating of bone.

Difficult problem: You have a difficult problem that may take several operations and several months to cure. You should see an orthopaedic surgeon who specializes in reconstructive trauma.
