This program is an electronic adaptation of work on the Comprehensive Classification of Pelvic Fractures by M. Tile, D. Helfet, J. Kellam, B. Isler, S. Nazarian, R.J. Judet, E. Letournel, and M.E. Müller. It includes sample X-rays, CT slices and 3D movies. In addition, a complete dictionary explains important terms and concepts, and a database is provided to record individual patient data such as fracture code, dates of treatment, and evaluation information. Multiple queries may be performed by fracture code or other criteria to retrieve an individual patient. With the use of this program careful classification and accurate documentation of treated fractures will facilitate research into the effectiveness of treatment.
