The procedure, which restores sensation to the stump of an amputated arm, was carried out on 22-year-old software engineering student Moses Mwendwa on April 29, 2025.
In an official statement, KNH announced: “We have performed the world’s first Transhumeral TSR surgery on Moses Mwendwa, 22, restoring sensation in his missing left arm. This revolutionary 7-hour surgery rerouted nerves to form a ‘sensory map,’ enabling tactile feedback and improved control of prosthetics.”
Mwendwa, who lost his arm in January due to compartment syndrome following a fall, underwent the procedure during TSR Camp—the first of its kind in Africa—held at KNH between April 28 and May 2.
“Feeling my hand again is magic,” Mwendwa told reporters.
The surgery was led by Prof. Ferdinand Nang’ole (Consultant Plastic Surgeon, KNH/UoN), Dr. Benjamin Wabwire (Head of Plastic and Reconstructive Surgery, KNH), and Prof. Alexander Gardetto (Plastic Surgery Specialist, Italy). They were supported by KNH’s Dr. Dorsi Jowi, Dr. Christine Nyabuto (chief resident, plastic surgery, UoN), and Dr. Rachel Machiya (resident orthopaedic surgeon, UoN).
Dr. Wabwire described the success as a transformative leap in medical science: “This isn’t just a breakthrough—it’s a restoration of dignity, hope, and functionality. We’re redefining possibilities for amputees.”
KNH CEO Dr. Evanson Kamuri praised the team’s accomplishment, emphasizing the hospital’s commitment to innovation and excellence: “This underscores the value of strategic partnerships and proves that KNH is home to world-class expertise and technology.”
KNH recounted Mwendwa’s medical journey, noting he was injured after a fall in Nairobi’s Ziwani area. After inconclusive evaluations at two other facilities, he was admitted to KNH where emergency surgeries were performed, eventually leading to the amputation of his dominant arm on January 24. The ordeal took a heavy emotional toll on both Mwendwa and his family.
