BORNEO: Evidence of the earliest known amputation was recovered from Liang Tebo Cave. The successful surgery was performed on a teenager 31,000 years ago, when the person’s lower left leg was skillfully removed. It is believed that the patient survived the procedure and lived for another 6 to 9 years before succumbing to an unknown cause of death. The individual also displayed signs of a healed neck fracture and clavicle trauma, both of which may have occurred during the same event in which the leg was injured.
