Abstract
EOS is a new tool in the armamemtarium of orthopedicians. Its ability to give a standing 3 dimesnionla image of the spine, has made it an indespenisble tool, specially for spine surgeons. Scoliosis is a 3 dimesnional deformity with multiple compensatory mechanisms being applied at the level of the pelvis and lower limbs as well as in spine. Operating on such patients needs thorough understanding of the 3D anatomy. EOS, provides this along with its low radiation dose, quick scan time and ability to repeat test multiple times if needed. The uses of this modality is on the rise, and as awareness and accessibility to EOS increases, so will the diversity of uses of this tool. Spine surgeons need to understand and use EOS for planning of their surgeries more compared to orther specializations of orthopaedics. EOS is truly a game-changer for spine imaging.
Keywords: EOS, 3dimesnional scans, scoliosis surgery, spine radiographs, novel methods
