Herniated Lumbar Disk
Conditions
Brief summary
This is a prospective, multi-center, randomized, controlled, patient and evaluator-blinded clinical study to assess the safety and effectiveness for the reduction of pain and symptoms following lumbar surgery.
Interventions
Oxiplex is a clear, viscoelastic gel that is applied to operative site during lumbar spine surgery in order to coat the nerve root with a protective barrier.
Single level partial discectomy as per standard of care procedures.

Eligibility
Inclusion criteria
1. Be between 22 and 70 years of age; 2. Have symptomatic posterior or posterolateral disc herniation at L4-L5 or L5-S1 with radiographic confirmation of nerve compression using MRI that requires partial surgical discectomy with or without laminotomy; 3. Have radiculopathy (e.g., decreased motor strength, sensory deficits, decreased reflexes) from specific nerve root distribution from L4 to S1 with positive straight leg raise (0-60 degrees); 4. Have at least one of the following: 1. At least six weeks of prior conservative treatment (e.g., physical therapy and/or use of anti-inflammatory medications, narcotics, and muscle relaxants at the manufacturer's recommended therapeutic dose); 2. The patient is experiencing intractable pain; or 3. There is substantial progression of loss of neurological function. 5. Have VAS leg pain score in the ipsilateral leg of at least 60mm on a 100mm scale; 6. Have VAS back pain score of at least 50mm on a 100mm scale; 7. Be appropriate for treatment using a posterior surgical approach; 8. Be likely to return for all follow-up visits; and 9. Be willing and able to provide Informed Consent for study participation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in ipsilateral leg pain | Pre-op; 6 weeks; 3 months; 6 months | Subjects will complete a Visual Analogue Scale (VAS) for their ipsilateral leg pain at each visit. The VAS is a continuous and linear, scale ranging from No Pain to Worst Possible Pain. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in back pain | Pre-op; 6 weeks; 3 months; 6 months | Subjects will complete a Visual Analogue Scale (VAS) for their back pain at each visit.The VAS is a continuous and linear, scale ranging from No Pain to Worst Possible Pain. |
