Selective Retention of Bone Marrow Stromal Cells with Gelatin Sponge for Repair of Intervertebral Disc Defects after Microendoscopic Discectomy: A Prospective Controlled Study and 2-Year Follow-Up

<div>A unilateral posterior superior iliac crest puncture was performed; a total of 30 mL of BMA was harvested (a). Then, BONE GROWTH PROMOTER (B1) was used to filter and enrich BMSCs into the gelatin sponge cubes (B2); after 6 cycles of enrichment, the composite was fully prepared for implantation (B3). The composite was inserted into the AF defect (c) using an insert tube (d). After the implantation procedure, AF was sutured using a Disposable Annular Stapler (e).</div>
