1850s, British surgical literature (Sir James Paget's descriptions of post-fracture median nerve dysfunction)
The condition now recognized as carpal tunnel syndrome accumulated a long prehistory of disconnected anatomical and clinical observations before it was coherently defined in the twentieth century. Surgeons and anatomists had long been aware of the median nerve's passage through the wrist, but the functional consequences of its compression were not systematically described until relatively late in medical history. The pathway from isolated curiosity to recognized clinical entity stretched across more than a century of incremental discovery.
Historical Narrative
The anatomy of the wrist and its enclosed structures attracted the attention of early modern European anatomists as dissection became a more systematized practice from the Renaissance onward. Andreas Vesalius and his contemporaries mapped the major nerve trunks of the upper extremity in the sixteenth century, and the median nerve's course through the narrow passage at the wrist was documented in these foundational anatomical works. However, the practical clinical significance of this anatomical arrangement was not explored during this period, as Renaissance anatomists were primarily concerned with description rather than the functional consequences of structural constraint.
The first clinical observations that can be retrospectively associated with median nerve compression at the wrist appeared in nineteenth-century surgical literature, largely in the context of wrist injuries and their sequelae. British surgeon Sir James Paget described cases of median nerve dysfunction following wrist fractures in the 1850s and 1860s, noting that patients developed hand weakness and sensory disturbances that he attributed to pressure on the nerve. Paget did not conceptualize this as a distinct entity but rather as a complication of trauma, and his observations were not synthesized into a broader framework.
German neurologist Georg Phalen is sometimes cited alongside earlier figures, but the more direct historical lineage runs through the early twentieth century, when the emerging specialty of neurology began to document cases of hand and wrist dysfunction that did not follow traumatic injury. James Learmonth, a Scottish surgeon, performed what is considered one of the earliest deliberate surgical decompressions of the median nerve at the wrist in the 1930s, and his operative reports represent a pivotal moment in the surgical history of the condition. Learmonth's work demonstrated that the symptoms patients had been experiencing could be relieved by releasing the transverse carpal ligament, even if the theoretical framework for why this worked remained incompletely articulated.
The formal clinical delineation of the syndrome as an independent entity is most strongly associated with George Phalen, an American orthopedic surgeon at the Cleveland Clinic, whose publications in the late 1940s and through the 1950s systematically described the clinical features, proposed the mechanism of nerve compression within the carpal tunnel, and advocated for surgical release as a definitive treatment. Phalen's prolific case series and his clear articulation of the anatomical rationale gave the condition its modern clinical identity. His name became so associated with the history of the condition that a clinical maneuver used by physicians in the mid-twentieth century bore his name.
Prior to Phalen's consolidating work, the condition had been variously attributed to occupational neuritis, menopausal changes in women, and vague rheumatic processes. The nineteenth and early twentieth century medical literature described women in middle age as particularly susceptible, and some physicians attributed the hand complaints of this demographic to hormonal or constitutional factors rather than mechanical compression. The idea that the anatomy of the wrist itself could act as a trap for the nerve, independent of injury or systemic disease, required a shift in mechanical thinking about nerve pathology that Phalen and his contemporaries were instrumental in driving forward through the postwar decades of the twentieth century.
