The most interesting in the film is perhaps a surgery scene fairly late in the movie., to correct the spine of a 17 year old boy who had had polio. The method used is by tranplanting ground bone.
After the surgery the boy was surely layiing immobilized for some time with intimate functions taken care of by catheters, and in a body cast, since the back had to be absolutely still until the bone had grown solid. They say he would be up after some days, but the cast would be on for several months. He is not shown right after surgery, since it probably would look more scary than the surgery itself.
What comes thereafter is an interview with a boy that apparently had such surgery, possibly the same boy, in a body cast but walking up.
Thwo collegues of mine talked together about having had spine surgery in that hospital, but it looked like their memories from the hospital were predominantly good, though, but they did not tell any details.
Nowadays one also uses metal rods or the like to hold the spine rigid after surgery. Thereby one does not need so long imobillization, but having a rod in the back is not good either.
The film begins with a authoritative doctor telling about the imobilization methods used on children having hip defects, and then imobilized children are shown, but those are allowed some activity though.
The doctor, an orthopedic surgeon, was 56 years old at that time. He died in 1971 from pancreatic cancer. I always check biographical facts about persons appearing in movies.

In the talk in Norweagian one says several times how smart and clever the doctors are "nowadays", a hype I remember well from my childhood at that time, but that I never really believed in, lol, and still not believe in.
