For many patients living with chronic pain, a spinal cord stimulator represents a last resort, one final option for relief when medication and surgery have already failed. That trust doesn’t always hold. Roughly 30% to 40% of implant recipients experience complications, and the FDA has logged more than 80,000 device-related injury reports over the past decade, among the highest counts for any medical device. A 505-patient study at a St. Louis, MO, pain clinic found a 14.1% explantation rate, with many devices removed after losing effectiveness.
As the global market for these devices, valued at $3.3 billion in 2025, continues to expand, so does the population exposed to nerve damage, infections, burns, and loss of mobility when hardware fails. These outcomes are prompting families across Missouri and beyond to explore a spinal cord stimulator failure lawsuit, arguing manufacturers rushed flawed designs to market. Regulatory gaps, including approval shortcuts that skipped fresh clinical testing, have only intensified scrutiny. This post breaks down how these failures happen and what affected patients can do next.
Why Device Failure Matters
A malfunctioning system might deliver erratic impulses, stop working, or cause painful stimulation. Burning sensations, muscle spasms, weakness, numbness, and worsening pain deserve medical review rather than simple adjustment. People researching possible harm often find a spinal cord stimulator failure lawsuit while seeking information about device defects, surgical errors, inadequate warnings, or delayed treatment. Such research can help patients prepare focused questions for physicians and attorneys without replacing individualized professional advice.
Common Mechanical Problems
Leads can fracture, migrate, disconnect, or press against nearby tissue. Scar formation sometimes changes electrical contact and reduces therapeutic coverage. A failing battery can cause abrupt treatment loss or unexpected shocks. Revision procedures carry additional risks, including retained fragments, bleeding, and infection. Device interrogation, radiographic studies, operative reports, and follow-up notes can help determine whether hardware failure preceded the patient’s symptoms.
Nerve Damage and Pain
Electrical current must remain within the intended treatment area. A displaced lead can irritate nerve roots or create sharp, electric sensations. Tissue injury during placement or removal may produce weakness, altered feeling, or impaired coordination. Serious compression can interfere with walking, bladder function, or bowel control. Some signs appear during recovery. Others emerge later, as swelling, scarring, or infection places continued pressure on sensitive structures.
Signs That Need Attention
New leg weakness warrants urgent evaluation, particularly if both limbs are affected. Falls, spreading numbness, severe balance problems, or difficulty controlling urine or stool require immediate attention. Fever, drainage, warmth, and redness near an incision can signal infection. Repeated shutdowns, sudden shocks, or escalating pain also need prompt review. A dated symptom record should note severity, duration, triggers, and changes after programming adjustments.
How Delayed Care Raises Risk
Waiting can permit infection, inflammation, or nerve irritation to progress. Some patients interpret increasing pain as a return of the original condition and postpone evaluation. That delay can complicate diagnosis and limit treatment choices. Physicians might order device testing, magnetic resonance imaging, blood work, or surgical exploration. Reporting symptoms early gives clinicians a clearer timeline and allows comparison with recent procedures, settings, and physical changes.
Evidence Can Clarify Events
Records can establish whether a device problem preceded lasting harm. Important materials include consent documents, surgical reports, programming logs, imaging results, medication lists, and therapy notes. Input from the following sources may also work well as evidence:
- Family members or coworkers might describe changes in walking, sleep, concentration, employment, or personal care.
- Photographs can document swelling or wound changes.
- A daily journal adds precise dates and observations, preserving details that become difficult to recall months later.
Who May Face Responsibility
Responsibility depends on the specific cause and available proof. A manufacturer could face allegations involving defective hardware, insufficient warnings, or unsafe instructions. A surgeon’s technique, placement decision, removal process, or follow-up care might also receive scrutiny. Hospitals and clinics can bear responsibility if staff ignored warning signs or failed to arrange appropriate testing. More than one party might be involved, but each allegation requires evidence linking conduct to injury.
Steps After an Injury
Patients should contact their treating physician after unusual symptoms begin. Emergency care is appropriate for paralysis, severe weakness, fever, rapidly spreading numbness, or loss of bodily control. Individuals should avoid changing settings without clinical guidance. Copies of records should be requested and stored securely. Packaging, receipts, appointment messages, medication changes, and employment documentation can also matter. Written statements should remain factual, dated, and free from unsupported conclusions.
Medical Review and Recovery
Treatment varies based on the location, severity, and cause of injury. Doctors might reprogram the system, prescribe medication, treat infection, remove hardware, or perform revision surgery. Physical therapy can address weakness, loss of balance, and reduced mobility. Pain specialists may adjust medication while neurologists assess nerve function. Psychological care can help patients manage sleep disruption, fear, and reduced independence. Follow-up visits track recovery and identify new warning signs.
Legal Options and Timing
A legal assessment can examine whether defective equipment, improper care, inadequate warnings, or delayed response caused measurable harm. Potential damages can include medical expenses, lost earnings, rehabilitation costs, physical pain, emotional distress, and future care needs. Filing deadlines differ by state and by the parties involved. Special rules may apply to public hospitals or government entities. Early advice helps preserve records and identify responsible parties.
Conclusion
Spinal cord stimulator failures can produce more than temporary treatment loss. Infection, nerve irritation, weakness, and severe pain may affect work, mobility, relationships, sleep, and personal independence. Medical attention should come first after concerning symptoms appear. Clear documentation can support diagnostic decisions, recovery planning, and later review of responsibility. Patients facing persistent harm deserve direct answers from qualified clinicians, along with informed guidance about their legal options.
