Combined Subchondral, Intradiscal and Peridiscal BMAC Injections for Advanced Degenerative Discs and Endplates with...

Degenerative disc disease (DDD) with cartilaginous endplate degeneration and Modic type 1 or 2 changes is increasingly recognized as a source of chronic vertebrogenic and discogenic low back pain. Because the intervertebral disc and vertebral endplates function as a biological and biomechanical unit, regenerative strategies targeting both structures may better address the disc-endplate complex.

Thirteen consecutive patients with chronic refractory vertebrogenic and/or discogenic low back pain, MRI evidence of DDD with Modic type 1 or 2 changes, and failure of conservative management underwent combined intradiscal, peridiscal, and subchondral bone marrow aspirate concentrate (BMAC) injections under fluoroscopic guidance. Four patients had previously undergone basivertebral nerve radiofrequency ablation. The cohort included 6 men and 7 women with a mean age of 56.2 ± 17.5 years. Follow-up ranged from 4 to 15 months. Mean Visual Analog Scale scores decreased from 7.3 ± 2.0 at baseline to 2.1 ± 1.6 at latest follow-up, a mean reduction of 5.2 ± 1.8 points (72.7% ± 19.5%). All patients achieved at least 50% pain reduction and reported functional improvement. Twelve patients (92.3%) were satisfied or very satisfied, and all would recommend the procedure. No major procedure-related complications were observed.

Combined intradiscal, peridiscal, and subchondral BMAC injections were associated with substantial pain reduction, functional improvement, high patient satisfaction, and no major complications in this small retrospective case series. Larger prospective controlled studies are needed to confirm these preliminary findings.
