The Use of PRP and BMC in Patients With Internal Disc Disruption Multicenter Prospective Randomized Controlled Trial in Patients With Internal Disc Disruption
- Conditions
- Internal Disc Disruption
- Interventions
- Procedure: Intradiscal PRP & BMC Injections
- Registration Number
- NCT04102761
- Lead Sponsor
- Annu Navani
- Brief Summary
The condition being studied is chronic low back or leg pain in patients with internal disc disruption (IDD). The intervention to be studied is the intradiscal delivery of autologous Platelet Rich Plasma (PRP) or bone marrow concentrate (BMC) into the nucleus pulposus of the disrupted disc(s).
- Detailed Description
This multi-center randomized controlled pilot trial will be the first to evaluate the response of PRP and BMC for discogenic pain by direct comparison. The investigators propose to incorporate a crossover design that compares placebo to two treatment modalities (i.e. Neutrophil-Poor PRP \[NP-PRP\] and BMC).
If the investigators can demonstrate statistically significant and clinically meaningful improvements in study's primary and secondary outcome measures, this study will have identified a natural, effective and sustainable treatment for discogenic back pain that currently accounts for the highest level of disability in US. This will help guide physicians in the choice of care between surgical and conservative treatment options when treating patients.

Group Intervention Description Trigger Point Needling Intradiscal PRP & BMC Injections The first group will receive a deep trigger point injection of saline into deep tissue. Bone Marrow Aspirate Injection Intradiscal PRP & BMC Injections The third group will receive an injection of approximately 1-2 mL of Bone Marrow Concentrate into the painful disc/discs. Platelet Rich Plasma Injection Intradiscal PRP & BMC Injections The Platelet Rich Plasma group will receive an injection of approximately 1-2 mL of Platelet Rich Plasma into the painful disc/discs.
- Primary Outcome Measures
Name Time Method Worsening of Disc Pathology with Injection of Biologics 24 weeks post procedure Pre and post op discs will be examined and compared for worsening pathology.
Improvement in Disc Pain with Injection of Biologics 24 weeks post procedure Pre and post op Pain will be measured and compared by Numeric Rating Scale (NRS) Numeric Pain Rating Scale (NRS): Measured from 0-10, 0 minimum score (better outcome) and 10 maximum score (worse outcome) Oswestry Low back disability (ODS): Measured from 0-50, 0 minimum score and 10 maximum score. The numbers are then calculated into percentages between 0% (minimum disability- better outcome)-100% (maximum disability- worse outcome) NASS Patient satisfaction Index (NASS): Measured from 0-4, 0 (better outcome) and 4 (worse outcome)
Improvement in Function in Patients with Injection of Biologics 24 weeks post procedure Pre and post op function will be measured and compared by Oswestry Disability Index (ODI)
- Secondary Outcome Measures
Name Time Method Hospitalization Pre injection, 1 month post op, 3 months post op, 6 months post op, 1 year. Hospitalization will be measured by patient's self report.
Spine Surgery Pre injection, 1 month post op, 3 months post op, 6 months post op, 1 year. Spine Surgery will be measured by patient's self report.
Medications Pre injection, 1 month post op, 3 months post op, 6 months post op, 1 year. Medications will be measured by patient's self report.
Patient Satisfaction Pre injection, 1 month post op, 3 months post op, 6 months post op, 1 year. Patient satisfaction will be measured by the modified North American Spine Surgery (NASS) Outcome Questionnaire
