Quantitative in vivo assessment of bone allograft viability using 18 F-fluoride PET/CT after glenoid augmentation in reverse shoulder arthroplasty: a pilot study

Background Success after glenoid bone augmentation in total shoulder arthroplasty depends on osseous integration and non-resorption. Standard imaging techniques, such as computed tomography (CT) and X-rays, cannot quantify bone viability. Therefore, we introduce a new technique to assess graft viability using 18F-sodium fluoride (18F-NaF) PET–CT for femoral allografts in reverse total shoulder arthroplasty (RSA).
