Effect of simulated early weight bearing on micromotion and pullout strength of uncemented distal femoral stems.

abstract：:A retrospective cohort study was conducted to compare fusion rates achieved by H-grafts, posterior vertebral grafts, and no graft for the surgical treatment of thoracolumbar fractures. Ninety-two patients were included in this study. The patients fell into 1 of 3 groups: those who received H-grafts (n=36), posterior v...
