Thermal osteonecrosis and bone drilling parameters revisited [PDF]
Archives of Orthopaedic and Trauma Surgery, 2007 During the drilling of the bone, the temperature could increase above 47 degrees C and cause irreversible osteonecrosis. The result is weakened contact of implants with bone and possible loss of rigid fixation. The aim of this study was to find an optimal condition where the increase in bone temperature during bone drilling process would be minimal ...
