According to Chapter 34, what medical treatments were attempted for the bone-cyst before the family sought Sai Baba's help, and why did they fail?

Chapter 34 explains that the nephew of the Malegaon doctor suffered from a bone-cyst that was considered a most difficult and extraordinary malady. Before turning to spiritual intervention, they exhausted all medical avenues. The chapter mentions that the boy's uncle was a degree-holding physician, and he, along with his physician friends and expert surgeons, tried various treatments. Specifically, the text states that "All native and foreign treatments were tried; all efforts were exhausted. Even surgery was attempted, but nothing succeeded." The treatments failed simply because the disease showed no improvement, leading the medical experts to feel helpless and exhausted.
