Operation Straight Spine (OSS) is a series of short films made in partnership with the charitable mission of the same name. Michael Tacca directed, wrote, and edited these documentary shorts in Kolkata, India. OSS is an ongoing charitable mission project, which provides treatment of spinal disease and deformity for the poor and under-served in India. OSS was founded by spinal surgeons, Jeff McConnell, MD and Ujjwal Debnath, MD, FRCS. This service provides comprehensive medical and state-of-the-art surgical care to children and adults from socially deprived areas who would not otherwise have access or could not afford such treatment.
