The ambulance crew were incapable of diagnosing a dislocated shoulder?? It’s fairly obvious & not exactly difficult to pop back in place. When it happens in motorcycle accidents whoever was riding with the guy who crashed usually pops it back in place even before the ambulance has been called.

Yes they were 95% certain of this. It is their job to asess,stabalise and transport the casulty to Hospital.

Please read the following from the NHS Website and then I will add further comments.

Most dislocated shoulders should be treated in a hospital A&E department.

Your shoulder is first X-rayed to make sure you haven’t broken any bones. It’s fairly common for someone who has dislocated their shoulder to also break the top of their humerus, the arm bone running from the shoulder to the elbow. A fractured humerus is most likely to happen in older people, whose bones have weakened with age. Read about the treatment of a fractured humerus in our page on broken arm.

The X-ray will confirm whether the shoulder has dislocated and can reveal if the rotator cuff tendons have torn – these are the bands of tissue that stretch over the top of the shoulder. It is common to tear a rotator cuff tendon and also the labrum, the cuff of tough tissue surrounding and supporting the shoulder joint. Rotator cuff tears are more likely to happen in older people, whose tissues are weaker.

Your arm will be supported in a sling, with your elbow bent at a right angle, and a pillow may be placed in the space between your arm and chest to provide comfort and support. Both the pillow and sling will be secured to your chest.

Your arm will then be gently manipulated back into its shoulder joint, using a procedure known as reduction.

Surgery is sometimes necessary if the tissues surrounding the joint are badly torn and the joint is not stable. If the tissues are not torn but overstretched, then surgery can be avoided by doing appropriate exercises to strengthen the shoulder (see below).
Reduction

You will be given some medication to sedate you, which ensures you are relaxed and as pain-free as possible.

Reduction will usually be carried out in the A&E department, but sometimes it is done in the operating theatre under general anaesthetic (you are put to sleep).

You will usually sit on the bed while the doctor rotates your arm around the shoulder joint until it goes back in its socket. This may take a few minutes.

Once the shoulder joint is back in place, you may have another X-ray to check the bone is in the correct position and there’s no other injury.

Now may I point out this was done as above.
My wife is 70years old and the Ambulance Crew would not know if she suffered from a lack of bone density which may have given her even more extreme injury if they did as you suggested.

Even the Doctor did not attempt to treat her without an Xray first!

I believe you are from the USA can you imagine all the Ambulance Chasers buzzing about if they got this one wrong.

It will take 12-16 weeks for this to heal and bad pain for the next 2-3 weeks.

Shame she was not a knuckleheaded young motocycle rider then!
