Purpose
Electrical burns of the finger caused by metal rings are uncommon but potentially severe due to circumferential thermal conduction and the confined anatomy of the digit. These injuries may appear minor initially yet can progress to vascular compromise, scarring, and functional impairment. This case series describes the clinical features and management of ring-associated electrical burns and proposes a practical treatment algorithm to guide early assessment and intervention.
Methodology
We retrospectively reviewed three patients presenting with electrical burns to the finger secondary to conduction through a metal ring. Data collected included demographics, mechanism of injury, burn depth, neurovascular status, management, complications, and functional outcomes. A treatment algorithm was developed based on case findings and established burn management principles.
Results
Two male and one female patients aged 46–57 years presented following accidental contact between a metal ring and a live electrical source. All sustained circumferential burns at the ring site with mixed-depth injury, including a full-thickness component. Initial management prioritised urgent ring removal and wound debridement, followed by hospital admission for serial neurovascular monitoring. Two patients were managed conservatively with dressings and hand therapy, while one required escharotomy under local anaesthetic for evolving vascular compromise. No patients developed compartment syndrome or required amputation. All achieved satisfactory wound healing within four weeks, with preservation of protective sensation and functional range of motion.
Conclusion
Electrical ring burns represent a distinct hand injury with potential for deep circumferential tissue damage disproportionate to initial appearance. Early recognition, prompt ring removal, careful neurovascular assessment, and timely surgical intervention when indicated are essential. We propose a treatment algorithm incorporating injury mechanism, burn depth, and perfusion status to guide management and optimise outcomes.
