Fortunately, revision lumbar surgery can give you the relief you\u2019re looking for. NU-Spine: The Minimally Invasive Spine Surgery Institute provides spinal procedures\u00a0and treatment for patients in New Jersey, Florida, and Pennsylvania. Here, we discuss lumbar fusion revision surgery\u00a0and how it can help provide relief from common surgery side effects.Key TakeawaysLumbar fusions fail for several reasons, including nonunion, hardware malfunctions, and adjacent segment disease (ASD).Revision surgery can address complications and side effects, such as pain, weakness, and limited mobility, by resolving the root cause of the failure.NU-Spine: The Minimally Invasive Spine Surgery Institute provides complex revision procedures in New Jersey, Florida, and Pennsylvania.What Are the Causes of Failed Lumbar Fusion?Lumbar fusion\u00a0is often successful, but there are also times when it leads to complications or fails to provide the pain relief patients are looking for. This is referred to as a failed lumbar fusion or failed back surgery syndrome (FBSS). Some causes include:Pseudarthrosis and nonunion: Pseudoarthrosis, which means false joint, is a nonunion where a bone fracture or spinal fusion fails to heal properly. It creates a mobile, fibrous gap instead of solid bone, leading to pain and instability.Hardware failure: Hardware failure can include screw loosening, breakage, or malposition. It often results from nonunion, osteoporosis, or excessive stress, and can lead to persistent pain, palpable lumps, and numbness.Adjacent segment disease (ASD): This is a long-term complication where degeneration occurs in the spinal levels above or below the fusion, leading to pain and neurological issues.What Are Symptoms That May Signal the Need for Revision Surgery?Patients who have had previous spine surgery and are now dealing with symptoms or side effects may require revision surgery to resolve the issue causing problems. Symptoms that suggest the need for revision surgery include:Persistent or worsening pain after initial fusionNew leg symptoms, such as weakness or imbalanceNew or worsening neurological symptoms like numbness and tinglingSigns of infection, such as fever, redness, or drainageReduced mobility and functionVisible or functional changesThese symptoms may indicate the need for revision surgery, but not always. It\u2019s important to see your doctor about complications or side effects you\u2019re experiencing to see what the best solution is.What Is the Workup Before Lumbar Fusion Revision Surgery?Before receiving a lumbar fusion revision surgery, the patient will need to undergo a thorough workup so the doctor can assess the problem and determine the best path forward. It includes:Imaging options: Imaging scans, such as X-rays, computed tomography (CT), and magnetic resonance imaging (MRI), are often used to get detailed images of the spine and the previous fusion. It can tell the surgeon whether there is nonunion, ASD, or hardware malfunctions.Diagnostic injections and nerve blocks: These tools are often used before revision spine surgery to identify the exact pain source and determine the failure source. They also help to improve accuracy and confirm the necessary surgical level.These processes help the surgeon confirm whether revision spine surgery is necessary and whether it will help to relieve the patient\u2019s symptoms.What Techniques are Used in Revision Lumbar Fusion Surgery?If the surgeon determines that revision lumbar fusion surgery is the best treatment option, there are several techniques that may be used. The option used depends on the cause of the failure:Hardware removal and replacement: If the failure is a result of hardware malfunctions, the solution may be to remove the faulty pieces and replace them with new ones.Extension of fusion: If the cause is nonunion, the surgeon may extend the fusion to adjacent levels or add a new bone graft to address it.Revision decompression: For patients dealing with ASD, the surgeon may perform decompression, which involves removing scar tissue, bony growths, or disc material that is compressing spinal nerves.Although revision surgery can effectively address side effects and complications, it also has lower success rates, higher complication rates, and longer, more complex recovery periods\u00a0compared to first-time surgery. Patients will need to have realistic goals for pain relief and function, which their surgeon can advise them on.Find Treatment for Complex Spine Revision Cases Near You in New Jersey, Florida, and PennsylvaniaIf you\u2019re struggling with complications or pain after spine surgery, you may need lumbar fusion revision surgery to get relief.

Revision lumbar surgery is a second procedure performed after a previous lower back surgery has not healed properly, has caused complications, or has not relieved symptoms. We use a detailed diagnostic process to understand the source of pain before recommending any surgical plan.How do I know if my spinal fusion never healed?Symptoms like persistent pain, instability, weakness, or numbness can indicate a failed fusion. However, imaging is required for a definitive diagnosis.Is revision lumbar surgery riskier than the first surgery?Yes, revision lumbar surgery is typically riskier than the first surgery because there is a higher likelihood of complications from the increased complexity, scar tissue, and altered anatomy. However, these surgeries can still successfully relieve pain when they\u2019re performed by experienced surgeons.How long is the recovery after revision fusion?Recovery after revision spinal fusion typically takes six months to a year or more for full recovery.When should I request a second opinion after lumbar fusion? We recommend requesting a second opinion if you have persistent pain, new leg symptoms, numbness, weakness, reduced mobility, or concerns about hardware after a prior fusion. A second opinion can help determine whether your symptoms are related to nonunion, hardware failure, adjacent segment disease, or another spine condition.Does adjacent segment disease always require surgery? No. Adjacent segment disease does not always require surgery. We recommend a full evaluation to determine whether symptoms can be managed conservatively or whether decompression, extension of fusion, or another procedure may be appropriate."},{"@context":"https:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Blog","item":"https:\/\/www.nu-spine.com\/blog\/#breadcrumbitem"},{"@type":"ListItem","position":2,"name":"Revision Lumbar Surgery: Pseudarthrosis, Hardware Pain, ASD","item":"https:\/\/www.nu-spine.com\/blog\/revision-lumbar-surgery-pseudarthrosis-hardware-pain-asd\/#breadcrumbitem"}]}]
