Abstract

Objectives: In this study, we intended to reveal the trabecular structure of hamate by using micro-computed tomography.
Methods: This study was carried out on 55 human dry hamates. The bones were scanned with a micro-CT device. Volume, surface, and trabecular parameters (trabecular number, trabecular thickness, trabecular separation) of the scanned bones were analyzed.
Results: The mean percentage of the bone volume was 44.930±5.859%, trabecular number was 1.31±0.150 mmˉ¹, trabecular thickness was 0.35±0.056 mm, trabecular separation was 0.57±0.087 mm.
Conclusion: Hamate has sufficient strength for screw implantation in terms of trabecular thickness and number, but weaker in terms of trabecular separation when compared with other carpal bones. Hamate has the greatest trabecular thickness among the other carpal bones, while it is ranked as the second in terms of trabecular number.
