The Chronic LBP Patient – Healthcare Burden

LBP is the most common cause of job-related disability1

• Impacts 29% of the population2

• $150-200 billion in annual healthcare expenditures3

• 33 million people disabled4

• 102 million lost workdays annually5

The Case for Vertebrogenic Pain

LBP patients with MC vs. LBP patients without MC

• MC changes were associated with persistent LBP1

• These patients seek care more often2, however,

• MC1 with chronic LBP associated with poor outcomes to conservative treatment3

• MC1 patients had worse outcomes after discectomy, underscoring the role of the

vertebra as a possible pain generator4

• MC were associated with historical LBP, and with severity and duration of symptoms

• Highly significant treatment effect against standard care (p < 0.001) in INTRACEPT Study

• SMART Trial data supports durable results at 2 years*

• Adverse event profile and animal studies support safety

• No serious device related AEs; procedure AEs mild in severity

• No regeneration of nerve, no avascular necrosis, or biomechanical instability post-ablation

• Modic Changes have clinical implications

lifestyles.

• Spinal stenosis is the result of aging and “wear and tear” on the spine from everyday activities. These changes cause the canals in the spine to narrow which can “pinch” the nerves in the lower back. This is called lumbar spinal stenosis (LSS). The result is pain, numbness, tingling and/or weakness in the back and legs.

What is Spinal Stenosis?LIGAMENT

Clinical Presentation of Lumbar Spinal Stenosis

✓ Standing/walking provokes symptoms

✓ Pain/weakness in legs

✓ Patient lean forward while walking to move around more comfortably: “Shopping Cart Sign”

✓ Sitting (flexion) relieves symptoms

Traditional treatments for LSS

• Conservative Care (Non Surgical)• NSAIDs (Aspirin, Advil, Aleve, etc.)

• Epidural Steroid Injections

• Reduced Physical Activity

• Physical Therapy

Traditional Surgical Treatments

• Surgical Treatment Options• Laminectomy

• Laminectomy and Fusion

Bridging the Gap in the Continuum of Care

What is Superion®?

This device is implanted by minimally invasive methods through a small cannula.

Superion® is a spinal implant designed to treat symptoms of moderate lumbar spinal stenosis (LSS).

The Superion® procedure is reversible and will not remove the structures (bones or tissue) of the spine. All future treatment options will still be available.

Patients who will benefit the most from the Superion® implant are those whose symptoms are relieved when bending forward, such as when pushing a shopping cart.

VF-LD-0119-A

Neurogenic Intermittent Claudication (NIC)

Canal and foraminal space for nerves increase in FLEXION

Canal and foraminal space for nerves decrease in EXTENSION

Superion restricts EXTENSION

Preventing extension reduces or eliminatesthe compression of nerves at the implanted level(s)

Procedural Flow

Physician gains access through a small incision in your lower back.

The implant that best fits your anatomy is delivered in a single step.

The surgical site is then closed.

Note: general anesthesia is not required for this procedure.

Procedural Flow

Patient’s Pre-Operative ImagingPre-Operative MRIs, Sagittal

Sagittal MRIs allow your physician to visualize your

spinal canal and look for any stenosis. This also helps

determine what the operative level should be.

Patient’s Pre-Operative ImagingPre-Operative MRIs, Axial L4/5

Axial MRIs (or top/bottom views of specific segments of your spine) allow your physician to determine the degree of central canal stenosis as well as any lateral or foraminal stenosis.

Patient’s Post-Operative Imaging

For 6 weeks, limit all lifting, bending, and strenuous activity including:

• Lifting any weight over 10-15 lbs.

• Any large bending of the spine, especially twisting.

• Strenuous activity such as swimming, golf, tennis, racquet ball, running, jogging, or remodeling/RV projects

Increase your light activity, such as walking, as tolerated.

Post-operative care guidelines

Tracking Patient Satisfaction• The Superion® system offers a safe and effective alternative to other more invasive surgical

options, such as decompression or spinal fusion.

• It has been thoroughly tested for the treatment of leg pain symptoms associated with moderate spinal stenosis.

• The clinical trial was regulated by the FDA. 471 patients were enrolled in the trial.

• Among those patients in the clinical trial that were followed up through five years, almost all expressed overall satisfaction with the Superion® implant.

For Direct Neural Inhibition, Frequency MattersResults of Preclinical Research into Frequency Effects on Nerve Types

• 10kHz frequency can drive inhibitory neurons without meaningfully activating excitatory neurons.

• This effect was not achieved at 1 or 5 kHz

Omnia Case Study

Patient Profile

• Implant date: August 14, 2019

• Battery swap of SJM IPG; Omnia IPG with existing SJM perc leads at C2

• Pain areas: Predominately bilateral arm, shoulders, and upper extremities

Results

• Baseline pain score: 9

• Pain score at last follow up: 1.3

• Patient prefers frequency pairing (HF10 + LF) program

• Patient has been reporting 85%+ pain relief in upper extremities, arms, and shoulders since her battery was swapped. She is extremely active as she farms so after bailing hay for 8 hours a day, she enjoys switching over to tonic for a few hours as she reports it is a nice distraction and she doesn’t lose the pain relief that she has gotten in her upper extremities.
