Treatment for an aneurysmal bone cyst (ABC) can vary depending on the lesion's location and the degree of damage it has caused to the bone.
Surgical Methods:
If the lesion is confined to a specific area within the bone and can be completely removed surgically, complete excision of the cyst is necessary. However, the possibility of microscopic cyst cells remaining behind can increase the risk of recurrence.
Adjuvant Therapies (Liquid Nitrogen Treatment):
To prevent the recurrence of ABC, adjuvant therapies such as chemical methods (e.g., liquid nitrogen, phenol, or alcohol) are applied to destroy even unseen cyst cells. Specifically, when liquid nitrogen is sprayed onto cyst cells within the bone, the environment is instantaneously cooled to -180°C and then brought back to room temperature, ensuring the breakdown and destruction of cyst cells. After ensuring that all cyst cells have been completely cleared, the resulting cavity is filled with a bone graft or bone cement (a special chemical alloy). Bone cement is often preferred due to its mechanical strength and its ability to inhibit cyst recurrence.
Wide Resection and Bone Grafting:
If the aneurysmal bone cyst is located in small bones and has caused significant bone destruction, the entire affected bone may be removed and replaced with a bone graft.
