Removal of septic foci in putrid infection of the bone is an important step in the treatment of post-traumatic osteitis. The methods employed so far, such as through-drainage and siphonage, as well as gentamycin-PMMA chains, have very obvious drawbacks although they have definitely achieved favourable results. Taurolin Gel , a preparation consisting of denatured collagen in combination with the chemotherapeutic Taurolin 4%, is theoretically capable of eliminating these drawbacks. Clinical application appeared justified on the basis of good results obtained with the drainage solution of Taurolin, as well as in the course of experiments. Results have been obtained mostly in a single application in 50 cases documented and followed up; these results were equivalent to those obtained by means of the other methods. In consideration of the advantages with regard to application and effect, the authors believe that testing of this substance on a larger scale should be recommended.
