Last August in Githunguri, Kiambu County, 8-year-old Nathan Kibiro began experiencing severe pain above his knee. Initial hospital visits diagnosed osteomyelitis, a bone infection, and prescribed medication. However, Nathan’s pain persisted, prompting further tests.
At Kenyatta National Hospital (KNH), Dr. Catherine Muendo, a pediatric hematologist-oncologist, recommended immediate chemotherapy. Initial biopsy results surprisingly indicated no cancer, but the doctors remained concerned.
“The biopsy didn’t match the X-rays or clinical signs,” Dr. Muendo said.
Confirmation of Osteosarcoma
Dr. Nicholas Okumu, an orthopedic surgeon, performed a new biopsy using a camera to examine the bone. The results confirmed osteosarcoma, or bone cancer.
Many doctors advised immediate amputation to prevent cancer from spreading. Nathan, a young football enthusiast, worried about his dreams. His parents sought alternatives, even considering traveling to India for treatment.
Innovative Limb Salvage Surgery
Dr. Okumu offered a groundbreaking solution: limb salvage surgery, a procedure where the cancerous bone segment is removed, treated, and re-implanted, allowing the leg to remain intact. Using biological reconstruction, the treated bone acts as a scaffold for natural regeneration—ideal for children.
“To my knowledge, this was the first time this procedure had been done in Kenya,” Dr. Muendo confirmed.
The Eight-Hour Surgery
On December 1, 2024, Nathan underwent an eight-hour surgery at AAR Hospital in Kiambu. Prior chemotherapy cleared cancer that had spread to his lungs, making the procedure feasible.
Nathan is now pain-free, recovering with a cast, and continuing chemotherapy to eliminate any remaining cancer cells. He will have regular check-ups over the next five years to ensure he remains cancer-free.
Impact and Cost
Had the family traveled to India, expenses would have been overwhelming. Instead, they spent Sh2.5 million to Sh3 million, relying on savings and family support. The Social Health Authority (SHA) covered only hospital bed costs.
Nathan’s story highlights advancements in Kenya’s medical field and the determination of his family to pursue innovative treatment.
“Before the surgery, we were in a very dark place. Now, I feel hopeful,” said Simon Kibiro, Nathan’s father.
