The hospital in Sacramento is the only hospital in the Shriners' system that focuses on all three areas of treatment (burns, orthopaedics, and spinal cord injuries), as well as research. The Sacramento hospital also houses its own orthotics and prosthetics lab and development facilities. Transportation to the hospitals is often provided free of charge for patients and their family by Shriner-drivers (also known as Hospital Tripsters) across the country, by van or by airplane. Children accepted for treatment become part of the Shriners Hospital system until their 18th or, sometimes, their 21st, birthday, eligible for both inpatient and outpatient treatment for all facets of their disability.
