Medical evidence, including the US government sponsored AHCPR meta-analysis, has indicated that 85-90% of LBP will resolve within 6-12 weeks with only palliative (symptomatic) care; therefore many physicians question whether more specific intervention is really necessary during this period.

However, recent longitudinal studies suggest that back pain is typically recurrent in nature, even if the original symptoms resolve, and many patients suffer chronic, unremitting symptoms at intervals. Studies indicate that over 60% of patients with acute LBP, suffered at least one recurrence in the following year. The high incidence of recurrence and chronicity point to the inadequacy of current management protocols, and warrants analysis and revision of our current treatment algorithms (standards).

The medical community, despite its appearance of being at the cutting edge of health advancements, can often be quite conservative when it comes to adopting new methods. If a patient does not experience a spontaneous resolution of their back problem within the first two months, an initial benign problem may become a chronic situation. This is why it is so important to institute early management that is effective.

Often patients recall that their back pain appears after periods of physical activity or prolonged periods of sitting or standing. Initially the pain may last a few hours or a few days and usually subsides with a limitation of the patient’s activity and medication. The pain pattern at this time is mechanical in nature, in the sense that it is usually made worse by standing, lifting, twisting, and prolonged sitting, and is often relieved by rest.

Since over 90% of clinically significant lumbar disc herniations occur at the L4-L5 or L5-S1 levels, the most common neurologic impairments are those of the L5 and the S1 nerve roots. Symptoms of disc protrusion are leg pain in a root distribution aggravated by lifting, coughing, laughing, sneezing and movements that increase intradiscal pressure. Important neurological signs are sensory deficits (tingling, numbness) in the legs and feet [L5-S1], reduced ankle reflexes [S1] and lower extremity weakness.

As the patient ages, painful episodes become more frequent or intense in nature, and may lead to more disability. The majority of these patients are not ideal surgical candidates. Specific therapy that targets disc pathology should be initiated early for these patients.

If low back pain symptoms have not resolved within four weeks, VAX-D should be considered (in the absence of contraindications) for those patients with a diagnosis of discogenic pain; including those with radiculopathy.
