The use of Reamer Irrigator Aspirator (RIA) autograft harvest in the treatment of critical-sized iliac wing defects in sheep: Investigation of dexamethasone and beta-tricalcium phosphate augmentation

► We investigated bone formation in a sheep iliac wing model using a RIA bone graft. ► Augmentation with beta-tricalcium biphosphonate granules increases bone formation. ► Other augmentation techniques showed no significant difference.
