New sterilization methods for human bone allografts may lead to alterations in bone mechanical properties, which strongly influence short- and medium-term outcomes. In many sterilization procedures, bone allografts are subjected to gamma irradiation, usually with 25 KGy, after treatment and packaging. We used speed-of-sound (SOS) measurements to evaluate the effects of gamma irradiation on bone. All...
The aim of this study was to evaluate the mechanical consequences of different common sterilisation treatments applied to human bone before transplantation. Ultrasound velocity measurements at low (LF) and high frequency (HF) were used as surrogate markers of structural (LF) and material (HF) elastic properties and failure stress. Cubic cancellous bone specimens (N=192) were obtained from human femoral...
