flag South African surgeon performs first liquid nitrogen bone-salvage surgery on 15-year-old boy.

flag A South African orthopaedic surgeon has performed the country's first limb-salvage surgery using liquid nitrogen to treat a 15-year-old boy with Ewing's sarcoma. flag The four-and-a-half-hour procedure removed a 24cm section of the boy's femur, froze it to kill cancer cells, and reimplanted it. flag This innovative technique, inspired by a Japanese method, aims to regenerate the bone and preserve joint function, offering an alternative to amputation or prosthetics.
