Your spinal cord stimulator failed — was that a device problem, a surgical problem, or both?
This article explains what clinicians are required to do when a Precision Spectra system is implanted and monitored, where that process commonly breaks down, and what that means for you.
What should have happened
Implanting a spinal cord stimulator is not a set-and-forget procedure. The surgeon who places the device carries responsibility for correct lead positioning and secure connector assembly. The clinical team managing your care after implant carries responsibility for monitoring device function, responding promptly to reported changes, and investigating hardware failure without unnecessary delay. When a lead fractures, a connector loosens, or an implanted pulse generator malfunctions, the question is whether the failure resulted from a surgical error, inadequate follow-up, or a delayed response to symptoms the patient had already reported.
A patient reports that her stimulation has become intermittent — present in the morning, absent by afternoon. Her neurosurgeon’s rooms tell her this is likely a programming issue and schedule a device check in six weeks. At that appointment, the technician adjusts settings. The problem continues. Three months later, imaging confirms a lead fracture at the connector site. She undergoes revision surgery. The fracture pattern is consistent with a technical error at the original implant. No one had ordered imaging when she first reported the change.
The lead was placed under tension — and it fractured
Lead fracture is the most common hardware failure in spinal cord stimulation systems. It does not always mean the device was defective. Leads fracture when they are placed with insufficient slack to accommodate spinal movement, when they are anchored incorrectly, or when the connector is not secured properly at the time of implant.
The surgeon controls all of these variables. A lead that fractures within months of implant — particularly at the connector site or at a point of mechanical stress — raises a direct question about surgical technique. When a patient reports loss of stimulation and the treating team delays imaging, that delay can itself cause harm: the patient continues without effective pain management, and a correctable problem becomes a more complex revision.
The connector was not secured — and the device never worked properly
Connector failure is distinct from lead fracture but produces similar symptoms: intermittent or absent stimulation, unexpected changes in sensation, or stimulation that shifts to the wrong area. A loose or incorrectly assembled connector at the extension-to-lead junction can cause all of these.
This failure is almost always a surgical error. The connector assembly is a discrete step in the implant procedure, and the surgeon is responsible for confirming it is secure before closing. When a patient reports stimulation loss in the early post-operative period and the clinical team attributes it to swelling or programming without investigating the hardware, a connector fault can go undetected for months.
The IPG malfunctioned — and the team did not investigate promptly
Implanted pulse generator malfunction is less common than lead or connector failure, but it does occur. When it does, the patient typically reports sudden loss of stimulation or unexpected changes in device behaviour. The clinical obligation is to investigate promptly — through device interrogation, imaging, and if necessary manufacturer review — and to keep the patient informed throughout.
Where teams fail is in attributing reported symptoms to other causes — pain fluctuation, psychological factors, or programming drift — without ruling out hardware failure first. A patient who reports a sudden change in their stimulator’s behaviour has given the clinical team a clear signal. Ignoring that signal, or delaying investigation, is a failure of the monitoring obligation.
- Your stimulation became intermittent or stopped working within weeks or months of implant, and your clinical team delayed ordering imaging.
- You reported a change in your stimulator’s behaviour and were told it was a programming issue — but the problem continued after reprogramming.
- You needed revision surgery to fix a lead fracture or connector fault, and no one explained what caused the original failure.
- Your surgeon or clinical team attributed your symptoms to your underlying pain condition rather than investigating the hardware.
- You experienced new pain — particularly at the implant site, along the lead path, or in areas previously covered by stimulation — and imaging was not ordered promptly.
- You were not told before surgery about the risk of lead migration, fracture, or connector failure, and you would have made a different decision had you known.
The records — the operative notes, the device interrogation logs, the imaging reports, and the clinical correspondence — will answer these questions far more reliably than anyone’s recollection. Time limits apply to medical negligence claims in Australia and vary by state and territory. If you are considering whether to look into this, sooner is better.
What happens next
A legal review of a spinal cord stimulator failure starts with the records. The operative report describes how the lead was placed and anchored. The device logs show when stimulation changed and whether the clinical team interrogated the device in response to your reports. Imaging timestamps show how long it took to investigate after you first raised a concern. These documents tell the story — independent of what anyone remembers or was told.
The goal of that review is an honest answer. Not to find fault for its own sake — but to determine whether the failure was avoidable, and whether the response to it met the standard your care required.

Her legal background allows her to read medical records — and then apply the law to what she finds. For spinal cord stimulator hardware failure, that perspective matters: the failures that cause harm often sit in the gap between what the operative notes show, what the device logs recorded, and what the patient was told at each stage.
Dr Listing’s work is focused on giving people an honest answer about whether what happened to them was avoidable. Many people wait a long time before looking into it. She understands why and applies a sensitive and caring approach to all her clients’ cases.
