Kenyatta National Hospital (KNH) has cemented its place on the global medical map by performing the world’s first Transhumeral Targeted Sensory Reinnervation (TSR) surgery a revolutionary procedure that restores sensation to an amputated arm.
The groundbreaking operation, performed on April 29, 2025, was conducted on 22-year-old software engineering student Moses Mwendwa. The seven-hour surgery successfully re-routed severed nerves from Mwendwa’s amputated left arm to remaining skin, allowing his brain to perceive sensations such as touch, temperature, and pain as if his hand were still present.
“For the first time since losing my hand, I can feel it again. That’s not just medicine it’s magic,” said Mwendwa, reflecting on his journey from trauma to hope.
The historic surgery was conducted during Africa’s first TSR Surgical Camp, hosted at KNH. A multinational team led the procedure, including Kenyan surgeons Prof. Ferdinand Nang’ole and Dr. Benjamin Wabwire, alongside visiting Italian expert Prof. Alexander Gardetto.
Dr. Wabwire, Head of Plastic & Reconstructive Surgery at KNH, said the success of the surgery marks a new frontier in post-amputation care. “By creating this neural hand map, we’re changing what’s possible for amputees. This achievement is not just a medical breakthrough it’s a restoration of dignity, function, and hope.”
The medical team was further supported by anaesthetists Dr. John Mwanzia and Dr. Ruth Nyambura, and surgical nurses led by Mr. Erick Odongo. Their collective expertise ensured the success of the complex procedure.
KNH CEO Dr. Evanson Kamuri praised the milestone, calling it proof of the hospital’s dedication to excellence through global partnerships. “This reaffirms our commitment to strategic collaborations and demonstrates that KNH is home to world-class professionals and cutting-edge technology.”
Mwendwa’s journey began in January 2025 after a fall following a church service in Nairobi’s Ziwani area, which led to a severe case of compartment syndrome. Following inconclusive diagnoses at two other facilities, KNH doctors intervened with emergency surgeries that culminated in the amputation of his dominant arm.
Now, thanks to this pioneering surgery, Moses and many like him have renewed hope for a future filled with possibility.
