Hi Thanks for your query and for usng health care magic
the Hospital you are talking about is "Balaji Institute of Surgery Research and Rehabilitation
for the Disabled” (BIRRD) Hospital at Tirupathi.
Its a charitable hospital.
They do not cure polio
as there is no cure. However, the do corrective surgeries and facilitate rehabilitation.
They have a very good tract record.
Hope this answers your query.
