[Augmentation in surgical sepsis : Chances and limitations in the treatment of osteitis with calcium hydroxyapatite containing antibiotics]. / Augmentation in der septischen Chirurgie : Chancen und Limitationen in der Behandlung der Osteitis mit antibiotikahaltigem Kalziumhydroxylapatit.

BACKGROUND: The surgical treatment of osteitis or fracture-related infections (FRI) is often associated with large bone defects. The treatment of these defects remains a major challenge in trauma surgery. Within the concept of tissue engineering, the development of various hybrid bone graft substitutes, such as calcium hydroxyapatite with added antibiotics, is continuously progressing. OBJECTIVE: Chances and limitations in the treatment of osteitis with calcium hydroxyapatite containing antibiotics. MATERIAL AND METHODS: Overview of the results of a 2-stage (infection) pseudarthrosis model on rat femurs treated with Cerament® G (Bonesupport, Lund, Schweden). Evaluation of the clinical experiences based on three case examples of osteitis treated with calcium hydroxyapatite containing antibiotics (Cerament® G or Cerament® V). RESULTS: After establishment of a 2­stage pseudarthrosis model on the rat femur, the osteoconductive and osteoinductive potential of calcium hydroxyapatite containing antibiotics could be confirmed. In the clinical application, the use of Cerament® G seems to lead to a more favorable outcome in small cavitary defects. The recurrence rates are higher than previously described, especially for larger segmental defects. CONCLUSION: Taking the clinical and experimental results into consideration, a stricter evaluation of the indications for the use of Cerament® G is necessary to achieve the best possible outcome for patients.
