KNH Makes Medical History with World’s First Transhumeral TSR Surgery
Kenyatta National Hospital (KNH) has achieved a historic global milestone by successfully performing the world’s first Transhumeral Targeted Sensory Reinnervation (TSR) surgery, a revolutionary procedure that restores sensation to amputated limbs.
The surgery was performed on April 29, 2025, on Moses Mwendwa, a 22-year-old software engineering student who lost his dominant left arm earlier this year. The complex seven-hour procedure rerouted severed nerves from Mwendwa’s amputated arm to intact skin, enabling his brain to interpret physical sensations like touch, temperature, and pain as if the limb 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 after the procedure.
TSR is a cutting-edge technique within the realm of plastic and reconstructive surgery, and the success of this procedure has placed KNH at the forefront of surgical innovation worldwide.
Dr. Benjamin Wabwire, Head of Plastic and Reconstructive Surgery at KNH, praised the achievement, stating, “This is not just a medical breakthrough. It is a restoration of dignity, function, and hope. By creating this neural hand map, we’re changing what’s possible for amputees.”
KNH CEO Dr. Evanson Kamuri lauded the team behind the groundbreaking surgery and emphasized the significance of strategic partnerships in elevating healthcare standards in Kenya. “This reaffirms our commitment to cutting-edge innovation and shows that KNH is home to world-class professionals and state-of-the-art technology,” he said.
The surgery took place during Africa’s first TSR Surgical Camp hosted by KNH, an initiative aimed at advancing post-amputation care across the continent. The operation was led by a multinational team comprising Prof. Ferdinand Nang’ole, Dr. Wabwire, and visiting Italian surgeon Prof. Alexander Gardetto. They were assisted by Dr. Dorsi Jowi, Dr. Christine Nyabuto, and Dr. Rachel Machiya. The anesthesia team included Dr. John Mwanzia and Dr. Ruth Nyambura, while the surgical nursing team was headed by Mr. Erick Odongo, supported by Ms. Mercy Chepkemoi, Ms. Esther Munga, and Ms. Catherine Muthengi.
Mwendwa’s journey to this medical milestone began in January 2025 when he suffered a fall after a church service in Nairobi’s Ziwani area. The incident resulted in a severe case of compartment syndrome—a life-threatening condition caused by excessive pressure within muscle compartments. After inconclusive diagnoses at two separate facilities, Mwendwa was rushed to KNH, where doctors performed emergency surgeries that culminated in the amputation of his arm on January 24.
KNH noted in a statement that the emotional impact on Mwendwa and his family was profound, with weeks of grief and adjustment. However, this unprecedented surgical success now offers not only renewed hope for Moses but a brighter future for amputees across the globe.
