jordonbmxsavidge,
Sorry about your injury.
It is kind of rare to sustain both a fracture of the humerus and dislocation of the shoulder, expect in the case of a proximal humeral head fracture where the articular surface is dislocated. But, these types are injuries are usually seen almost always in the elderly patient.
But, anything is possible, in the world of orthopedics.
By two pins and a wire, to an orthopedic surgeon, that means a construct of Steinmenn pins and a wire, which are being used to hold fracture fragments together.
(Then once the humerus is back together, then the shoulder can be reduced.)
This construct can be either a temporary construct that is to be taken out before therapy is started, or it can be a permanent construct.
But, there can be a problem in rehab. The exercises for the two injuries are a little different. But, nothing that can't be worked around.
As long as the humerus heals completely, it is at no higher risk of refracture that an uninjured bone.
As to the shoulder, that is a different story. If the ligament and capsule scar down so that there is no laxity, AND the patient builds the muscles back up around the shoulder girdle with a rigorous rehab program, then there should be no problems. But, if there is residual laxity in the shoulder joint, then it is at higher risk for redislocation.
But, of course, if the event of another high speed or high fall accident, who knows what can happen.
So, just be sure to do your therapy and rebuild all of your muscles before getting into situations where you are at risk of injury.
Good luck on your rehab.
