Bone scan in evaluation of bone viability in severe frostbite of the hand

A 39-year-old male presented to the emergency department (ED) with frostbite to the fingers of both hands. In the ED, he received warm baths, acetylsalicylic acid, clopidogrel, and heparin. A three-phase bone scintigraphy with technetium-99m-methylene diphosphonate revealed absent radiotracer uptake in distal phalanges of both hands. The patient received acetylsalicylic acid, clopidogrel and wound care for the next 5 days and made an excellent recovery with satisfactory wound healing in both hands. Early rapid rewarming and reperfusion can improve the prognosis significantly and therefore bone scan done within first 1-2 days may give spurious results.
