Owner Lennie Green of Industry Maine puts a prosthetic leg made by Derrick Campana on Angel Marie, a three-legged mini horse, during a visit to Campana at Animal Ortho Care in Sterling, Virginia, U.S., March 27, 2017. The certified orthotist at Animal Ortho Care in Sterling, Virginia fashioned prosthetic front legs using highly durable, medical grade plastics. He says watching Angel Marie take her first steps was emotional. “Seeing her walk, and having her here today walking is just a dream come true. A miracle”. Owner Lennie Green credits Campana with saving Angel Marie's life. Campana started his career in making orthotics for humans, and saw a niche for helping animals. He's become a go-to in the industry globally – he's fashioned a prosthetic limb for an elephant in Thailand that had it's front foot blown off by a land mine. While he is not a veterinarian, Campana says his practice is a cost-effective alternative to more invasive procedures at the vet. The future in prosthetics, he says, is likely in 3D printing, which he says is costly now, but may become more affordable in years to come – which will give furry pals near and far a leg up in life.
