6 months
Study Arms (2)
Conservative Medical Management
NO INTERVENTIONContinued medical management restricted to exclude interventional pain treatments
Axium Group
ACTIVE COMPARATORAs the CMM group but also treated with Dorsal Root Ganglion stimulation using the Axium neurostimulator
Interventions
Eligibility Criteria
You may qualify if:
- Subject is at least 18 years old
- Subject is able and willing to comply with the follow-up schedule and protocol
- Chronic inguinal pain following Pfannenstiel Incision or Open Inguinal Hernia Repair for at least 6 months
- Previously undergone neurectomy procedure as a treatment for chronic inguinal pain
- Minimum daily average baseline pain rating of 5 out of 10 in the inguinal area on an 11-point NPRS
- Subject is able to provide written informed consent
- Subject has been screened by a multi-disciplinary panel including the designated psychologist of the Máxima Medical Center and deemed suitable for implantation
You may not qualify if:
- Female subject of childbearing potential is pregnant/nursing or plans to become pregnant during the course of the Trial
- Escalating or changing pain condition within the past month as evidenced by investigator examination
- Subject has had injection therapy or radiofrequency treatment of a target neural structure within the past 3 months
- Subject currently has an active implantable device including implantable cardioverter defibrillator, pacemaker, spinal cord stimulator or intrathecal drug pump
- Subject is unable to operate the device
- Subjects currently has an active infection
- Subject has participated in another clinical investigation within 30 days
- Subject has a coagulation disorder or uses anticoagulants that, in the opinion of the investigator, precludes participation
- Subject has a current or on going condition, which will probably require MRI investigation sometime in the following 2 years
- Subject has had a spinal surgical procedure at or between vertebral levels T10-L2
- Subject has been diagnosed with cancer in the past 2 years, except for skin malignancies.
