Purpose: The purpose of this cadaveric study was to compare the volume and weight of bone graft harvested using the curettage vs. the trephination technique from the anterior iliac crest. Methods: Embalmed cadavers were studied in this experimental research. The right hemipelvis of each cadaver was used for the trephine bone harvesting technique, whereas the left hemipelvis was used for the conventional curettage technique. The weight and the volume of the harvested bone were measured and statistically compared between the 2 sides. The Wilcoxon Signed-Rank test was employed to compare the graft volume and weight obtained from the right and left sides of the hemipelvis. Results: Ten embalmed adult cadavers were used in this study. All subjects were Caucasian males with a mean age of 59.8 years (range 44 – 73 years) at the time of death. A total of 81 cylindrical bone grafts were harvested from the right iliac crest. In 9 out of 81 (11.1 %), the cortex of the ilium was penetrated by the chisel. The mean weight of the bone graft harvested with the trephine technique (26.97 ± 2.32) g was heavier than the curettage technique (23.74 ± 2.09) g (p = 0.007). Similarly, the volume of the bone graft was higher in the trephine technique (8.40 ± 0.84) cm3 compared to the curettage technique (6.60 ± 1.26) cm3 (p = 0.011). The trephination technique lasted a mean of (12.76 ± 1.87) min (range 10.30–16.10 min), while the curettage technique lasted a mean of (14.53 ± 0.89) min (range 13.50–16.00 min) (p = 0.028). Conclusion: Harvesting anterior iliac crest bone graft with the trephine technique provides a higher bone volume and weight than the conventional curettage technique. The trephine technique might be advocated over the curettage technique, especially when a large amount of autologous bone graft is required. However, a meticulous harvesting technique should be followed to prevent complications, particularly the three-dimensional anatomy should be kept in mind, and the depth of trephination should be well-controlled.
