Ancient skeletal remains, c. 3000–1000 BCE (paleopathological evidence from Egyptian and pre-Columbian archaeological sites); first clinical description by Sir James Paget, 1877
Paget's disease of bone was a chronic skeletal disorder characterized by abnormal bone remodeling, which remained poorly understood until the late nineteenth century when the British surgeon Sir James Paget provided the first systematic clinical and pathological description. For much of history, the condition's distinctive skeletal changes were either overlooked or conflated with other diseases affecting the bones. Paget's careful documentation of affected patients and post-mortem specimens in 1877 established the disease as a distinct entity and gave it a foundation for future investigation.
Historical Narrative
Evidence of what scholars later identified as probable Paget's disease of bone has been discovered in archaeological skeletal remains predating written medical records by thousands of years. Paleopathologists examining ancient Egyptian and pre-Columbian skeletal material in the twentieth century identified bony changes consistent with the condition, suggesting that it affected human populations long before any healer recognized it as a distinct illness. However, because ancient medical traditions — including those of Egypt, Greece, and Rome — lacked the anatomical and pathological frameworks necessary to distinguish one bone-altering condition from another, Paget's disease almost certainly went unnamed and unrecognized for millennia.
In ancient Greece, the Hippocratic corpus addressed diseases of the bones in broad terms, describing conditions of bone thickening and deformity without providing the specificity that would allow a retrospective diagnosis of any particular disorder. Galen of Pergamon, the enormously influential second-century Roman physician, elaborated on Hippocratic theories of bone disease within his humoral framework, attributing skeletal changes to imbalances of the four humors — blood, phlegm, yellow bile, and black bile — rather than to any structural pathology within the bone itself.
Medieval European medicine inherited and largely preserved this humoral framework, with scholastic physicians such as Avicenna — the eleventh-century Persian polymath whose 'Canon of Medicine' dominated European and Islamic medical education for centuries — discussing bone ailments in terms consistent with classical Greek theory. Avicenna described bone hardening and enlargement as consequences of corrupt humors settling in the skeletal structures, a conceptual model that offered no means of distinguishing Paget's disease from other conditions affecting bone density and shape.
The anatomical revolution of the Renaissance brought more precise observation of skeletal structure, and figures such as Andreas Vesalius, whose 'De Humani Corporis Fabrica' was published in 1543, corrected numerous Galenic errors through direct dissection. Yet systematic pathological correlation — linking the appearances of diseased bones at autopsy to the clinical histories of patients — remained underdeveloped until the eighteenth and nineteenth centuries.
It was Sir James Paget, the eminent Victorian surgeon and pathologist at St. Bartholomew's Hospital in London, who in 1877 published his landmark paper describing a condition he called 'osteitis deformans.' Paget had observed the same peculiar pattern of bone changes in several patients over the course of his career and, recognizing the consistency of the clinical and pathological picture, argued that it constituted a previously undescribed disease. He documented the progressive enlargement and deformity of the skull, spine, and long bones in affected individuals, and he carefully compared the gross and microscopic appearances of their bones at post-mortem examination with those of unaffected individuals.
Following Paget's description, European and American physicians began identifying additional cases and debating the underlying cause. Theories in the late nineteenth and early twentieth centuries ranged from chronic low-grade inflammation to metabolic disturbances, and the debate over whether the disease represented a form of chronic osteitis or a primary disorder of bone metabolism persisted for decades. Max Pommer and later researchers contributed microscopic analyses of the characteristic mosaic bone patterns visible in affected tissue, gradually elucidating the disordered sequence of bone resorption and formation that defined the disease at the cellular level.
