A felon is a purulent abscess within the volar pulp space of the finger — a small but high-risk compartment encased by tight fascial septae. Delays to timely treatment may compromise neurovascular structures and undermine bone and joint integrity. This portends significant risk of functional deficit. Pre-eminent ancient surgeons recognized the urgency of this soft-tissue-infection with propensity of functional destruction. Celsus (25 BC–50 AD) and Galen (129–c. 200 AD) denote advocated for early and aggressive incision and drainage. This pressure-relieving intervention was often performed without anaesthesia. Avicenna (Ibn Sina, 980–1037) then reported on progression of felons and deleterious consequences following missed or delayed diagnoses. Such classical texts illustrate the collective understanding and importance of early felon-infections. Initial invasive management options however conferred extensive scarring and stiffness with functional limitations. Surgical practice made significant progress in the 19th and 20th centuries, with enhanced understanding of pathophysiology, aseptic technique and antibiotic therapies. This, in conjunction with refined approaches to hand anatomy, have influenced our current management of felons. Standard practice involves a longitudinal volar pulp incision for emergent decompression and drainage. This preserves critical neurovascular structures and improves functionality. The paradigm-shift from aggressive and functionally limiting interventions to anatomically-precise surgical debridement reflects strides made in modern hand surgery. We recognise the foundations laid out by classical and pre-eminent surgeons. Their fundamental understanding of disease processes, centred on urgent incision and drainage, continues to guide critical surgical principles in management of felons today.
