Abstract: A bone trabecular structure, a prosthesis having the same, and a fabrication method thereof are provided. The bone trabecular structure includes a body configured to be a three-dimensional porous structure, which includes a plurality of struts and a plurality of pores formed by staggered connection of the plurality of struts. The pores are communicated with each other and have different average diameters. The average diameter of the pores ranges from 100 ?m to 400 ?m, and the porosity of the three-dimensional porous structure ranges from 50% to 80%. This bone trabecular structure facilitates postoperative bone ingrowth of a patient, and thus effectively improves the postoperative recovery effect of the patient.
