Pathology of the Bones and Joints T2 Pathology: The Big Picture YR 2008 FD 2008 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-147748-2 LK accessphysiotherapy.mhmedical.com/content.aspx?aid=57055819 RD 2024/04/20 AB Diseases of the bone include non-neoplastic disorders such as genetic defects (e.g., achondroplasia), osteoporosis, infections of the bone (i.e., osteomyelitis), and Paget disease. The age of the patient and the location of the tumor are very important considerations in the diagnosis of bone tumors. For example, most chondrosarcomas occur in older adults and almost never occur in the bones of the hands, whereas most Ewing sarcomas occur in the diaphysis of long bones of children.
