A fracture of the radial neck with a tilt in the head of radius means that there will probably be a restriction in forearm supination-pronation movements when it heals up. In an adult, it is more important to operate and stabilise it to allow for restoration of complete forearm movts in the future. The actual surgery required is small ( like just putting a steel wire across the reduced neck) but beneficial. You should see an orthopaedic surgeon and take a definitive opinion instead of shopping around. Also, during this phase , your husband should rest his elbow in a arm-pouch sling and keep it still and not use it. It may displace the fracture which would then definitely need an opeartion and a bigger one.
