Zhang Zhe, the child, actually suffers from chronic osteomyelitis. Chronic osteomyelitis doesn't require a pathological examination for diagnosis. A clear diagnosis can be made based on the patient's medical history, physical examination, and radiological examination.
However, any organs and tissues removed during surgery need to undergo a pathological examination - this is standard medical practice.
Song Zimo took this opportunity to study the pathological manifestations of this rare focal chronic osteomyelitis and to determine whether the surgery truly completely removed the diseased tissues.
To this end, Song Zimo asked the Pathology Department for assistance, and they made dozens of pathological slides from the entire bone fragment that was removed. This allowed for a detailed observation of the entire bone fragment.
