Spinal hardware removal surgery removes screws, rods, plates, cages, or other implants from a previous spine surgery when they cause pain, irritation, infection, loosening, or complications after spinal fusion. At Midwest Spine & Brain Institute (MSBI), board-certified spine surgeons perform advanced revision spine surgery and minimally invasive hardware removal procedures for patients across Minnesota and western Wisconsin.
What Is Spinal Hardware Removal Surgery?
Spinal hardware removal is a revision spine procedure used to remove implants placed during a previous spinal surgery, most commonly after spinal fusion. Hardware may include:
- Pedicle screws
- Rods
- Plates
- Interbody cages
- Hooks
- Spinal instrumentation systems
In many patients, spinal implants remain safely in place permanently. However, some patients develop pain, inflammation, nerve irritation, infection, hardware loosening, or failed fusion that may require additional evaluation and possible removal surgery.
Patients with persistent symptoms after fusion surgery may also benefit from evaluation for failed spinal fusion, pseudoarthrosis repair, or revision spine surgery.
Why Would Spinal Hardware Need to Be Removed?
Hardware removal may be recommended when spinal implants contribute to ongoing symptoms or complications.
Common Reasons for Hardware Removal
- Hardware loosening or instability
- Painful spinal instrumentation
- Nerve compression or irritation
- Infection around spinal implants
- Prominent hardware under the skin
- Broken rods or screws
- Failed spinal fusion (pseudoarthrosis)
- Adjacent segment degeneration
- Hardware migration or malposition
Patients may also experience symptoms related to underlying spine conditions such as:
- degenerative disc disease
- spinal arthritis
- spondylolisthesis
- spinal stenosis
Symptoms That May Indicate a Hardware Problem
Patients with spinal instrumentation complications may experience:
- Persistent back or neck pain
- Pain near prior incision sites
- Burning or radiating nerve pain
- Leg weakness or numbness
- Muscle spasms
- Swelling or redness
- Drainage from a surgical incision
- Pain with movement or standing
- Reduced mobility after fusion surgery
Symptoms can appear months or years after the original procedure.
How MSBI Diagnoses Hardware Complications
Accurate diagnosis is critical before considering hardware removal surgery.
Diagnostic Evaluation May Include
- Physical examination
- Surgical history review
- X-rays to evaluate hardware alignment
- CT scans to assess fusion healing
- MRI to evaluate nerves and soft tissues
- Infection testing or laboratory work
- Diagnostic injections in selected cases
MSBI specialists evaluate whether symptoms are caused by hardware itself, incomplete fusion, nerve compression, scar tissue, or progressive degeneration.
Patients with nerve-related symptoms may also require evaluation for pinched nerves, myelopathy, or sciatica.
How Spinal Hardware Removal Surgery Is Performed
Hardware removal surgery varies depending on the location of implants, fusion status, and underlying spinal condition.
During Surgery
The surgeon:
- Reopens the prior surgical incision
- Carefully removes scar tissue surrounding implants
- Identifies and protects nearby nerves
- Removes screws, rods, plates, or cages
- Evaluates spinal stability and fusion healing
- Performs additional stabilization if necessary
If the spine has fused successfully, hardware may be removed without additional fusion. If instability or pseudoarthrosis is present, revision fusion surgery may also be required.
Some procedures can be performed using minimally invasive spine surgery techniques, depending on anatomy and prior operations.
Surgical vs. Non-Surgical Treatment Options
Non-Surgical Management
Some patients improve without surgery through:
- Physical therapy
- Activity modification
- Anti-inflammatory medications
- Pain management injections
- Nerve medications
- Rehabilitation programs
When Surgery Is Recommended
Surgery may be considered when patients have:
- Persistent pain despite conservative care
- Confirmed hardware failure
- Neurologic symptoms
- Infection
- Progressive spinal instability
- Failed spinal fusion
Benefits of Hardware Removal Surgery
Potential benefits may include:
- Reduced pain and irritation
- Improved mobility
- Decreased nerve compression
- Resolution of infection
- Improved daily function
- Better quality of life
Outcomes depend on spinal stability, nerve health, fusion status, and the underlying cause of symptoms.
Risks and Complications
Like all spine procedures, hardware removal surgery carries risks.
Possible Risks Include
- Infection
- Bleeding
- Cerebrospinal fluid leak
- Nerve injury
- Incomplete symptom relief
- Recurrent instability
- Need for revision fusion surgery
- Scar tissue formation
MSBI surgeons use evidence-based surgical planning and advanced imaging guidance to improve safety and precision.
Recovery After Spinal Hardware Removal
Recovery time varies based on the extent of surgery and whether additional fusion is required.
Typical Recovery Timeline
- Walking usually begins the same day or next day
- Light activity may resume within several weeks
- Physical therapy often begins during recovery
- Full healing may take several months
Patients who undergo revision fusion or reconstruction may require longer recovery periods.
Can Spinal Hardware Be Removed Years Later?
Yes. In some cases, spinal implants can be removed years after the original surgery if they become painful, loosen, break, or contribute to nerve irritation or infection.
However, not all spinal hardware should be removed. Evaluation by an experienced spine surgeon is important before considering revision surgery.
When to See a Spine Specialist
You should seek evaluation if you experience:
- Persistent pain after spinal fusion
- Worsening neurologic symptoms
- Pain near surgical implants
- Signs of infection
- Difficulty walking or standing
- Progressive weakness or numbness
Early evaluation can help identify whether symptoms are related to hardware, fusion healing, or another spinal condition.

Frequently Asked Questions
What is spinal hardware removal surgery?
Spinal hardware removal surgery removes screws, rods, plates, or cages from a previous spine operation when implants cause pain, infection, loosening, or other complications.
Why would spinal hardware cause pain?
Hardware may irritate nearby muscles, tendons, or nerves. Pain can also occur if the fusion does not heal properly or if implants loosen over time.
Is hardware removal a major surgery?
It can range from minimally invasive outpatient procedures to complex revision spine surgery depending on the location of the implants and spinal stability.
Can spinal screws and rods stay in forever?
Yes. Many spinal implants remain in place permanently without causing problems. Removal is only recommended when symptoms or complications occur.
How long does recovery take after hardware removal?
Many patients recover over several weeks, although full healing can take months if revision fusion or reconstruction is needed.
Can spinal hardware removal help nerve pain?
If implants are compressing or irritating nerves, hardware removal may improve symptoms such as burning pain, numbness, or weakness.
What happens if spinal fusion did not heal correctly?
Incomplete fusion, also called pseudoarthrosis, may require revision surgery, bone grafting, or new stabilization procedures.
Is hardware removal covered by insurance?
Most medically necessary spinal hardware removal procedures are typically covered by insurance plans, although coverage varies by provider and policy.
Can infection require hardware removal?
Yes. Deep spinal infections involving implants sometimes require hardware removal combined with antibiotics and additional stabilization procedures.
Do all painful spinal implants need removal?
No. Some pain may come from scar tissue, arthritis, or adjacent spinal degeneration rather than the implants themselves.
