Pore size bone ingrowth
WebAn articular surface and cage technology, applied in the field of medical prostheses, can solve the problem of insufficient bonding strength of a porous structure cage, and achieve the effects of preventing burrs, increasing the contact area, and improving the strength WebBone ingrowth was determined using histomorphometry and a novel micro-CT image analysis. Substantial bone ingrowth was observed in implants that filled the defect site. Further validating this quantitatively by micro-CT, the Bone mineral density of the implant at the defect site was 1024 mgHA/ccm, which was approximately 61.5% more than the bone …
