In 2005, 49-year-old Arsenio Matias from the Dominican Republic was operating a vacuum form machine, used to press plastic parts into shape, when he accidentally cut off both his hands from the wrist down. When he saw blood pouring from his wrists and his two hands laying on the machinery, he thought he was going to die. But fortunately, two of Matias’s coworkers had the presence of mind to assist him by tying their belts around his arms (to minimize the loss of blood) and putting his hands in ice (to preserve them). Hours later, doctors at the Stony Brook hospital used microscopes and magnifying lenses to reattach Matias’s severed limbs. However, doctors expected the patient to regain only up to 50% of normal feeling and mobility in his hands. Nevertheless, just days later, Matias described how he felt as “Perfect, perfect. I never have pain. This is unbelievable stuff medically.”
