c. 1600 BCE — Ancient Egypt (Edwin Smith Papyrus; also evidenced in skeletal remains of earlier periods)
Historical healers and physicians observed and attempted to treat abnormal curvature of the spine for thousands of years, developing explanations that ranged from humoral imbalance to structural deformity of bones and intervertebral tissues. Ancient Egyptian and Greek medical traditions both left detailed records of spinal deformity, and the condition attracted sustained medical attention across many cultures and centuries. The effort to understand and correct the curved spine drove significant innovations in anatomical knowledge and orthopedic theory.
Historical Narrative
The earliest known descriptions of spinal curvature appeared in ancient Egypt, where the Edwin Smith Papyrus — composed approximately 1600 BCE but believed to transmit much older knowledge — contained observations of spinal injuries and their consequences. Egyptian physicians recognized that trauma to the spine could produce lasting deformity and loss of function, and certain mummies examined by modern archaeologists displayed skeletal evidence of significant spinal curvature, including cases consistent with what later generations would recognize as tuberculous infection of the spine.
Ancient Greek medicine produced the most systematic early engagement with spinal deformity. Hippocrates devoted considerable attention to the spine in his treatises On Joints and On the Surgery, describing various forms of curvature and attempting both explanation and correction. Hippocratic physicians distinguished between curvature arising from internal disease and that resulting from trauma, and they developed early mechanical interventions — including the use of the Hippocratic board, a device on which patients were strapped while practitioners applied pressure and manipulation — in attempts to reduce deformity. The Greek term kyphos, meaning hump or convexity, entered medical vocabulary in this period.
Galen expanded upon Hippocratic anatomical observations in the second century CE, refining the classification of spinal curvatures into kyphosis (posterior convexity), lordosis (anterior convexity), and scoliosis (lateral deviation). Galen's authority was such that his terminology and frameworks became the dominant vocabulary of European medicine for over a thousand years. His explanations grounded spinal deformity in humoral theory and the mechanics of bone and ligament, and his anatomical dissections, performed largely on animals, informed his descriptions of spinal structure.
Medieval European medicine largely preserved and transmitted Galenic frameworks, while Arabic physicians made notable contributions. The eleventh-century Persian physician Avicenna devoted sections of his encyclopedic Canon of Medicine to spinal diseases, including curvature, attributing some cases to softening of bones and others to inflammation or injury. Avicenna's work synthesized Greek and Islamic medical traditions and remained a standard reference in both Islamic and European medical education for centuries.
The Renaissance brought renewed engagement with human anatomy. Andreas Vesalius, whose 1543 De Humani Corporis Fabrica corrected numerous Galenic errors through direct human dissection, produced detailed illustrations of the spine that gave later practitioners a more accurate structural foundation. His work did not immediately transform treatment of spinal curvature, but it shifted the anatomical basis on which subsequent physicians reasoned about the condition.
The eighteenth century produced the first systematic orthopedic approaches to spinal curvature. Nicolas Andry de Boisregard, a French physician whose 1741 work L'Orthopedie coined the very term orthopedics, discussed the correction of spinal deformity in children through mechanical means and postural training. His influential tree-and-stake illustration became an enduring symbol of the orthopedic project. Later in the century, Percivall Pott, a British surgeon, described the destructive spinal curvature associated with tuberculosis — thereafter known as Pott's disease — in 1779, representing a major step in distinguishing disease-caused from structurally caused curvature.
The nineteenth century brought corsets, braces, and early surgical discussions into the management of severe curvature, and the development of anesthesia and antiseptic technique in the mid-to-late 1800s gradually made operative intervention conceivable in extreme cases.
