What medical treatments were attempted for the bone-cyst before the family went to see Sai Baba?

According to Chapter 34, the nephew of the Malegaon doctor was suffering from a bone-cyst (Hadyavarn) that was considered a "most difficult and extraordinary malady." Before turning to Sai Baba, they had exhausted all conventional medical options. The text explicitly mentions that since the boy's uncle was a degree-holding doctor, he and his physician friends tried numerous treatments. They attempted "all native and foreign treatments," and even resorted to surgery, but nothing succeeded. Expert and intelligent surgeons were left feeling helpless and exhausted, as the disease showed no improvement whatsoever.
