Hi
Welcome to the MedHelp forum!
This is really strange. If this is a non healing old fracture, a large one, and the fractured pieces are unstable, then only you need surgery. If it is a new fracture and you do not have a history of injury, then stress or pathological fracture will need to be ruled out. Please discuss all this with an orthopedic specialist, take a second opinion and then only go for surgery. Most sternal fractures heal on their own. Take care!
A sternum fracture will be treated by surgery,when there is a dislocation of the fragments ,when there is chronic pain with bad breathing ,or pseudarthrosis.After 2,5years,the surgeon must obviously break the sternum again,to bring all in the right position.Fixation is with wire or screws (very rare).It isn`t shure ,that pain is always disappearing.The convalecence time could be 1 to 3 month with muscle training.
With best regards
