Background. Advances in diagnostic imaging, neoadjuvant chemotherapy, and operative
technique have made it possible to treat malignant tumours of bone and soft tissue by limb
salvage. With multidisciplinary treatment, such techniques produce a functional and durable limb
without reducing the long-term results. All the established methods of reconstruction such as the
use of massive prostheses, allografts, combinations of allografts and prostheses or with
bonecement have made limb salvage possible.
Method. We describe a method of reconstruction using tumour-bearing autograft treated by
liquid nitrogen in 3 patients. The operative technique consisted of en bloc excision of the tumour,
removal of soft tissue, curettage of the tumour, bone recycling using liquid nitrogen, drilling and
preparation for internal fixation or prosthetic replacement. Bone graft or cement was used to
augment bone strength when necessary. Outcomes were assessed through Revised
Musculoskeletal Tumour Society Rating Score.
Result. From three patients with musculoskeletal tumour we already treated using liquid
nitrogen, two patients gave a positive respond to this treatment, while one patient has a local
recurrence. Our results suggest that this is a simple and effective method of biological
reconstruction
Conclusion. The effectiveness of this reconstruction technique in properly selected patients with
malignant bone tumor. Reconstruction with tumour-bearing massive frozen autograft treated by
liquid nitrogen in malignant bone and soft-tissue tumours is a simple and effective method of
biological reconstruction. Long-term follow-up studies will provide more useful information and
clarify the effectiveness of this study.
