[Frostbite of the upper and lower limbs in an expert mountain climber: the value of bone scan in the prediction of amputation level].

A 38 year old man was admitted to our hospital 10 days after suffering a frostbite injury in hands and feet while practicing mountain climbing, at 8,100 meters of altitude, while he was trying to reach the top of the K2 mountain. A 99mTc-MDP bone scan performed in aseptic conditions showed: in hands: absence of bone uptake in the 3rd phalanx and distal portion of 2nd phalanx of the 5th finger of the left hand, and multiple areas of increased uptake in the distal portion of both hands. In feet: uptake decreases in the 2nd phalanx of the first toe of the left foot, and absence of bone uptake in the 3rd phalanx of the 2nd toe of the left foot, and in 2nd phalanx of the 1st toe and 3rd phalanx of the 2nd, 3rd and 4th toes of the right foot. As in the hands, there were multiple areas of increased uptake in the distal portion of both feet. The phalanges with absence of bone uptake had to be amputated, while those that presented increased uptake recovered with conservative treatment. Bone scan is indicated in the evaluation of frostbite injuries and helps to establish the prognosis early.
