Mid-seventeenth century, European medical literature
Trigger finger, characterized historically by the sudden locking or snapping of a finger during movement, was recognized as a distinct mechanical curiosity long before its anatomical cause was precisely identified. Early physicians attributed the phenomenon to a variety of explanations ranging from humoral imbalance to joint dislocation, and formal surgical understanding of the tendon sheath as the site of pathology only emerged in the nineteenth century. The condition's history reflects the gradual shift from surface observation to anatomically grounded diagnosis that characterized modern surgical medicine.
Historical Narrative
The earliest descriptions of finger locking phenomena appear in European medical literature of the seventeenth century, though the condition almost certainly affected individuals throughout the ancient and medieval periods without receiving specific documentation. The agricultural and craft-based nature of most pre-modern labor meant that repetitive hand use was ubiquitous, and degenerative or inflammatory changes in the tendons of the hand were likely commonplace, even if healers of the era lacked the anatomical vocabulary to identify the precise structure at fault.
Seventeenth and eighteenth-century physicians who noted the snapping or locking of fingers generally attempted to explain the phenomenon within the framework of joint pathology. Some attributed it to small bony prominences or irregular joint surfaces that caught on one another during movement, while others invoked humoral concepts of thickened or viscous fluids accumulating within the joints and impeding smooth motion. Treatment during this period reflected these misattributions, with practitioners employing poultices, friction, and passive manipulation in attempts to restore free movement, guided by the assumption that the joint itself was the seat of the problem.
A clearer anatomical picture began to emerge in the nineteenth century as surgical anatomy reached greater levels of precision. French and German surgeons, benefiting from the improved access to cadaveric dissection that accompanied the reform of medical education in the post-Revolutionary era, were able to examine the fibrous sheaths surrounding the flexor tendons of the fingers in greater detail than before. The French surgeon Alphonse Notta is credited with publishing in 1850 what became recognized as the first systematic clinical and pathological description of the condition, identifying the nodular thickening of the tendon at the level of the first annular pulley as the mechanical cause of the locking phenomenon. The eponym "Notta's node" reflected this attribution for some time in European medical literature.
Notta's work fundamentally reframed the condition as a tendon sheath disorder rather than a joint disorder, and subsequent decades saw surgical intervention at the level of the sheath rather than the joint become the accepted approach among those advocating operative treatment. The late nineteenth century saw debates within surgical circles about whether division of the constricting portion of the sheath was preferable to conservative manipulation, and case reports from British, French, and German surgical journals documented various approaches and their outcomes.
The early twentieth century brought the condition into clearer clinical focus as orthopedic surgery developed as a defined specialty. Investigators began noting the condition's association with repetitive occupational hand use, and the term "trigger finger" — derived from the characteristic snapping release reminiscent of a gun's trigger mechanism — gained widespread currency in English-language medical literature during this period. Studies of industrial workers in the interwar years contributed epidemiological observations linking the condition to specific patterns of manual labor. By mid-century, the anatomical consensus established by Notta and refined by subsequent surgeons had become the standard framework within which the condition was taught and managed across Western medical institutions.
