Traumatology units need to follow-up the evolution of implanted patients in order to provide a high quality of life, and to detect possible failures in the design, fabrication or implanting procedure of prostheses.

PROTEO is a computer program that supports the surgeon in storing and processing relevant information for a reliable patient’s follow-up. Presently, the MIC provides two releases: PROTEO-KNEE and PROTEO-HIP, adjusted to the particular needs of knee and hip prostheses.

Basically PROTEO provides a user-friendly interface to feed the computer with the patient’s personal and clinical data, including subjective opinions, and medical measurements and imagery. Figure 1 illustrates this interface, where data for a given patient is always visible, as well as the score for each follow-up, computed according to a standard protocol.

But PROTEO is more than a specific database manager, it also implements algorithms to easily perform accurate clinical measurements on radiographies. These measurements are standard and determine the fitness of the knee- or hip-prostheses implantation. Figure 2 shows examples of measurements on radiographies.

Current developments will provide access through the Internet to databases of all medical centers that currently use PROTEO. The resulting distributed database will allow automatic knowledge discovery with parallel genetic algorithms, and queries over a number of cases that largely exceeds the average size of local databases, and hence the statistical validity of the results.
