Cryoablation in the treatment of bone cancer is a method aimed at destroying or inactivating tumorous bone tissue by freezing it. While it can be applied alone in some cases, it is generally used in combination with other treatment methods such as chemotherapy and radiotherapy.
Cryoablation is not directly applied in areas such as the brain, spinal cord, and regions with critical nerve density due to its potential to damage nerve tissue; however, it can be performed by protecting nerve tissue with special techniques. Furthermore, it is a more suitable option when the tumor has not extensively damaged the bone structure.
In this method, the tumorous bone is removed from the body, cleared of tumor tissue, and frozen in a liquid nitrogen bath at -180°C. The freezing process aims to preserve the bone's biological activity without significantly affecting its durability.
Different reconstruction methods are used to replace the frozen bone:
1. Its interior can be filled with antibiotic-containing bone cement to prevent infection.
2. A fibula bone taken from the other leg can be embedded into the frozen bone and connected to main vessels using microsurgical techniques. This method ensures the bone's vitality and supportive capacity.
Through this 'cryo-preservation' approach, the tumorous bone can be replaced in its original form, the risk of infection is minimized, and the bone can heal and integrate over time.
