Experimental quantification of resistance to subsidence conferred by endplate-specific expandable implants in anterior lumbar interbody fusion

In our study, endplate-specific expandable ALIF implants have shown higher resistance to subsidence than static implants. While, these results must be corroborated by clinical data, the superiority here identified indicates the potential for these implants to be advantageous over static implants. The linear correlation between the epiphyseal rim cross-sectional area of the endplate and the subsidence load, as found in the current study, highlights the potential for estimating the subsidence load during preoperative planning.
