Wider cuffs provide better transmission of tissue compression and lower cuff pressures are required to compress the artery and hence minimize potential pressure-related complications.19 In a cross-over volunteer study of 20 patients, all the patients were subjected to wide as well as narrow cuffs and it was found that wider cuffs (14 cm) were less painful than narrow cuffs (7 cm) if inflated at lower pressures and they were still effective at occluding blood flow.20 The cuff should not directly overlie bony prominences like the head of fibula or malleoli as there is risk of direct nerve compression.21 Hence, it is recommended that the edge of the tourniquet should be at least 2 cm distal to the head of fibula and 2 cm proximal to the malleoli in case of calf cuffs.21 It is recommended that tourniquets be avoided in fixation of simple isolated fractures of fibula as it may increase the time of recovery and postoperative complications.22 The length of the cuff should be individualized, according to the size and circumference of the patient's limb.
