Outcome Measures

Primary Outcomes (1)

  • Pain Management

    Numeric Rating Scale (NRS) Pain Intensity Scores completed by subjects three times per day from Day 0 to 3 months post treatment, then NRS weekly through 6 months post treatment. 2. The total daily opioid consumption from Day 0 to 6 months post treatment.

    Six Months

Secondary Outcomes (3)

  • Adverse Events and Serious Adverse Events

Study Arms (1)

Active Treatment

OTHER

As a Proof of Concept Study, 5 subjects will follow the same protocol, with one cryoanalgesic treatment (iovera°®) with a 6 month clinical follow-up.

Device: Cryoanalgesia (iovera°®)

Interventions

iovera°® treatment will be administered via ultrasound guidance to 1-2 branches of the dorsal/digital/proper nerve/s that innervate the Morton's neuroma. The treatment will be completed one time per subject.

Also known as: iovera°®
Active Treatment

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Healthy adult male or female volunteers ages 18 or older.
  • Able to provide informed consent, adhere to the study schedule, and complete all study assessments.
  • Body Mass Index (BMI) ≥18 and ≤40 kg/m2.
  • Unilateral Morton's Neuroma diagnosed by MRI.
  • Subject has failed conservative treatment options.

You may not qualify if:

  • Documented allergy, hypersensitivity, intolerance, or contraindication to amide-type local anesthetics (i.e., lidocaine), or opioids, NSAIDs.
  • Documented history of uncontrolled diabetes, bleeding disorder, severe Peripheral Vascular Disease (PVD).
  • Concurrent painful physical condition that may require analgesic treatment (i.e., long-term opioid use) which, in the Principal Investigator's opinion, may confound the treatment assessments.
  • History of, suspected, or known addiction to/or abuse of illicit drug/s, prescription medicine/s, or alcohol within the past 3 years.
  • Administration of an investigational drug or medical device within 30 days of the Screening Period.
  • Previous participation in a cryoneurolysis study.
  • Uncontrolled anxiety, schizophrenia, or other psychiatric disorder that, in the opinion of the Principal Investigator, could potentially interfere with study assessments or compliance.
  • Currently pregnant, nursing, or planning to become pregnant during the study.
  • Clinically significant medical disease that, in the opinion of the Principal Investigator, would make participation in a clinical study inappropriate.
  • Inadequate sensory function of the affected foot (as defined at the Screening Visit Neurologic Lower Extremity (LE) exams).
  • Any clinically significant event or condition uncovered during the Screening Period (e.g., contra-lateral foot injury) that, in the opinion of the Principal Investigator, renders the subject medically unstable or complicates the subject's study participation.
  • Subject has a history of: Cryoglobulinemia, paroxysmal cold hemoglobinuria, cold urticaria or Raynaud's Disease.
  • Subject has an active, wound, open and/or potential infection near the anticipated treatment site.
