An Unsung Hero of Ukraine

"There are fewer [bionic] arms available than lost ones."
"I now know a lot not only from textbooks but also from my own experience."
"I feel uncomfortable when I'm without the prosthesis."
"But when I have the bionic arm on, I feel comfortable. It's like a part of you."
Alexis Cholas, volunteer combat medic, hospital rehabilitation specialist, Ukraine

Since the conflict that Russia inflicted on Ukraine in February 2022, an estimated 20,000 Ukrainians have suffered amputations; soldiers for the most part, whom blast wounds caused the loss of arms or legs. Ukrainians can access artificial limbs through the country's public health-care system. Artificial limbs are available to anyone who needs them, free of charge. Conventional artificial limbs cost between $800 and $2,800. But a bionic artificial limb, a far more sophisticated device enabling the wearer to perform tasks of a delicate nature, have a far higher cost, up to $50,000.

So, while the state steps in to provide a basic replacement of an amputated limb, anyone with thoughts of being able to replace natural fine motor skills to allow for an amputee to continue working in a profession requiring delicacy of movement in fine-tuned mode, would yearn for a bionic arm. That type of costly prosthetic enables natural and fluid movements, unlike the functionality of the basic artificial limb. 

26-year-old Alexis Cholas lost his right arm while operating as a volunteer combat medic close to the front lines in eastern Ukraine. With that, his profession as a surgeon was no longer possible. Despite which, as one of a small number of amputees, he was fitted with a bionic prosthesis, far more advanced than the basic, providing greater mobility. Thanks to his bionic hand, his movements are natural and fluid, enabling him to remove a bandage with ease, and dress a patient's wounds on his own, without nursing assistance.

Bionic artificial limbs are sophisticated replacements picking up electrical signals from the muscles above the amputation site in bioelectric technology that functions in carrying out an intended motion. Before 2022, the manufacturer of the bionic arm installed for Dr. Cholas by Esper Bionics targeted the U.S. market until a sharp rise in demand in Ukraine for prosthetic limbs leading to Esper distributing 70 percent of its products now in Ukraine.

Produced in Kyiv, the company is working at full tilt, over 30 workers producing roughly a dozen bionic hands monthly. A small group of engineers program, assemble and test the bionic arms known as Esper Hand. Despite ramping up production, the company struggles to meet demand. Close to 120 people are on the wait list for the prosthetic which, in Ukraine, the company absorbs no profit for, selling the arm for about $7,000, enough to just cover production, whereas the hand sells in the U.S. for over $20,000.

Another feature of the Esper Hand is artificial intelligence, powering an ability to adapt over time, as it learns the wearer's unique interactions with the hand. Dr. Cholas returned to volunteering as a combat medic on the front lines once he was outfitted with his bionic arm. He maintains his day job in Kyiv as a rehabilitation specialist in a public hospital, where his patients are members of the military or civilians who have lost limbs. His own amputation experience aids him in developing rapport with his patients.
