Initial Jamshidi needle bone defect edge and bone repair at 3 months postoperative at the repair tissue-bone interface below the bone plate. Nondecalcified plastic sections were stained with von Kossa (black stain for mineral phosphate) and toluidine blue (blue = protein, violet = glycosaminoglycan) from day 1 (A) and 3 months postoperative showing new woven bone (B, treated defect), and endochondral ossification at the interface of mature chondrogenic foci and trabecular bone (C and D, control defect). White arrows show mineral formation inside mature chondrogenic foci.
