Historically, the treatment of malignant bone tumors often involved limb amputation. With advancements in surgical techniques and chemotherapy, limb-sparing procedures, frequently utilizing prosthetic implants, became standard. However, concerns regarding the longevity and cost of prostheses have spurred increasing interest in biological reconstructive methods.
Liquid nitrogen (cryotherapy) in the treatment of malignant bone tumors offers several significant advantages:
1. Long-term Autologous Integration: Although the healing process may be slower than with prosthetic surgery, patients benefit from living with their own native bone throughout their lives. This is a crucial advantage, especially for pediatric patients, as it minimizes the need for multiple revisions associated with prosthetic implants.
2. Preservation of Bone Stock: Repeated prosthetic revisions can lead to substantial bone defects, potentially depleting suitable bone volume for future reconstructive options. Cryotherapy helps preserve the patient's own bone structure, circumventing this issue.
3. Reduced Long-term Infection Risk: While an initial risk of infection exists, it significantly diminishes after the first few months. In contrast, prosthetic infections often require complete implant removal, leading to considerable financial costs and further loss of healthy bone tissue.
4. Complete Functional Restoration: Patients must exercise caution during the initial bone healing phase. Once healing is complete, typically within 1 to 2 years, patients can fully resume all activities, including aggressive sports, without long-term restrictions.
