توضیح
The hand surface area (HSA) is estimated at 1% and a total of about 3% of the body surface area (BSA). So, hand burn functional impairment is of great importance. Electrical or chemical hand injuries are associated with high morbidity. Generally, second or third-degree hand burns are considered a major burn injury, and it is mandatory to refer them to the burn center [1-3]. Contracture following hand burns is common, and movement limitations could decrease quality of life, significantly. Therefore, initial management by a specialized medical care team is crucial [4-7].
Hand injuries usually occur due to occupational exposure to hazardous conditions, natural disaster, or recreational accidents [8]. Electrical burns occur directly due to the electrical current or following severe muscle contractions induced by an electrical current. Electrical voltage also determines the severity of burn injury [9]. Overall, low-voltage injuries cause local skin burns at the contact sites, while high-voltage burns may damage skin tissue. High-voltage burns also cause indirect injury at the entry and exit of electricity flow site, generally referred to as entrance and exit wounds [10]. Moreover, electrical burn damage is related to the object's resistance, the electrical current passes through it, and the duration of contact [8, 9]. Ring burn injuries are a particular type of low-voltage injuries, in which electrical current passes through the ring worn on fingers. Metal rings could cause a circumferential burn, which is sometimes deep. Electrical damage occurs when energy flows through the body due to contact with an electrical source. Injuries occur due to either the flow of current through the …
