Clinical Trial Summary

Bone marrow aspirate (BMA) in association to graft substitutes has long been introduced as a promising alternative to iliac crest bone graft in spinal fusion. However, BMA use is limited by the absence of a standardized technique, of a physical texture and by the possibility of dispersion away from the implant site. Recently, the potential use of a new formulation of BMA, named BMA clot, has been preclinically described. A prospective pilot clinical study designed to assessing the safety and efficacy of autologous vertebral BMA (vBMA) clot as multifunctional bio-scaffold in instrumental posterior lumbar fusion will be performed.

Intervention

Biological:
Vertebral bone marrow clot
vBMA will be harvested from each patient vertebral pedicle with the preparation of the site for pedicle screw insertion during spinal surgery. After the positioning of pedicle screws, the decompression of the cauda and nerve roots will be achieved with a hemilaminectomy and foraminotomy. vBMA clot will be opposed on the hemi-laminae and transvers process on the contralateral side of the hemilaminectomy. On the hemilaminectomy side, foramino-arthrectomy will be performed to insert the interbody fusion cage if necessary. After aspiration, the vBMA will be clotted and used for surgical procedure. vBMA clot will be applied on each side of the vertebra according to the number of segments to be fused.

Outcome

Type Measure Description Time frame Safety issue
Primary Brantigan classification Improvement of spinal fusion rate and time in patients treated with vBMA clot associated to bone allograft chips in comparison to bone allograft chips alone, also considering age and gender differences. CT-scan and X-ray, perform pre-operatively and at FUs, will be evaluated basing on Brantigan classification (which ranges from A to E, with E score indicating better SF rate). At baseline (day 0)
