What Are the Risks of Spinal Surgery? A Patient’s Guide to Understanding and Preparing
Are you considering spinal surgery? It’s completely understandable to feel a mix of hope and anxiety. The prospect of alleviating chronic back pain or resolving a debilitating spinal condition can be exciting, but it’s also natural to have questions and concerns about the potential risks involved. At Legent Spine, we believe that informed patients are empowered patients. This guide is designed to provide you with a clear and comprehensive overview of the risks associated with spinal surgery, helping you make informed decisions in partnership with your doctor.
Back pain can be debilitating, significantly impacting your quality of life. Spinal surgery might seem like the only viable solution when other treatments have failed. Before making such a significant decision, it’s crucial to understand the potential risks involved. This isn’t meant to scare you, but rather to equip you with the knowledge you need to navigate this process with confidence.
While spinal surgery can be life-changing for many, offering significant pain relief and improved mobility, it’s important to acknowledge that, like any medical procedure, it carries potential risks. The goal is to minimize these risks through careful planning, a skilled surgical team, and diligent post-operative care. Our commitment at Legent Spine is to ensure you receive the highest quality care, prioritizing your safety and well-being every step of the way.
For the purpose of this article, “spinal surgery” encompasses a broad range of procedures, including but not limited to discectomy (removal of a herniated disc), laminectomy (decompression of the spinal cord or nerves), and spinal fusion (joining two or more vertebrae together). Each of these procedures addresses different spinal conditions and carries its own unique set of potential risks.
This article will explore the common and less common risks of spinal surgery, discuss factors that can influence those risks, and provide guidance on how to minimize your personal risk profile. Our aim is to provide you with the information you need to have a productive and informed conversation with your spine specialist.
General Risks Applicable to Most Spinal Surgeries
Certain risks are inherent in almost all types of spinal surgery. Understanding these general risks is the first step in preparing for surgery and knowing what to watch out for during your recovery.
Infection
The risk of infection is present in any surgical procedure. In spinal surgery, infection can occur at the surgical site, either superficially (in the skin) or deep within the tissues surrounding the spine. The incidence of infection after spinal surgery is relatively low, but it’s a serious complication that requires prompt treatment.
Signs and symptoms of infection include redness, swelling, increased pain at the incision site, fever, chills, and drainage from the wound. It’s crucial to monitor your incision site closely and report any of these symptoms to your doctor immediately.
Preventative measures are taken to minimize the risk of infection, including administering pre-operative antibiotics, using strict sterile techniques during surgery, and ensuring a clean surgical environment. At Legent Spine, we adhere to the highest standards of infection control to protect our patients.
Treatment for infections typically involves antibiotics, either oral or intravenous, depending on the severity of the infection. In some cases, further surgery may be necessary to drain the infection and remove any infected tissue.
Bleeding
Excessive bleeding can occur during or after spinal surgery. While surgeons take precautions to minimize blood loss, some bleeding is inevitable. The amount of bleeding varies depending on the type of surgery, the patient’s overall health, and other factors.
Potential complications from bleeding include hematoma formation (a collection of blood under the skin), which can cause pain and pressure on surrounding tissues, including nerves. In rare cases, significant blood loss may require a blood transfusion.
Before surgery, your doctor will assess your bleeding risk by reviewing your medical history, medications, and any pre-existing clotting disorders. Certain medications, such as blood thinners, may need to be stopped prior to surgery to minimize the risk of bleeding.
Blood Clots (Deep Vein Thrombosis – DVT and Pulmonary Embolism – PE)
Blood clots can form in the legs (deep vein thrombosis, or DVT) after spinal surgery, particularly if you are immobile for extended periods. These clots can then travel to the lungs (pulmonary embolism, or PE), which is a life-threatening condition.
Symptoms of DVT include swelling, pain, redness, and warmth in the leg. Symptoms of PE include shortness of breath, chest pain, and coughing up blood. If you experience any of these symptoms, seek immediate medical attention.
Preventative measures are crucial to reduce the risk of blood clots. These measures include compression stockings, which help to improve blood circulation in the legs; blood thinners, which prevent clots from forming; and early ambulation (getting up and walking around) after surgery.
Anesthesia Risks
Anesthesia is an essential part of spinal surgery, allowing you to remain comfortable and pain-free during the procedure. However, anesthesia also carries certain risks.
Common side effects of anesthesia include nausea, vomiting, and sore throat. These side effects are usually temporary and can be managed with medication.
Rare but serious risks of anesthesia include allergic reaction, breathing problems, and cardiac complications. Your anesthesiologist will carefully monitor you throughout the surgery to minimize these risks.
It’s essential to discuss your medical history, allergies, and any previous experiences with anesthesia with your anesthesiologist before surgery. This information will help them to choose the safest and most appropriate type of anesthesia for you.
Nerve Damage
The spinal cord and nerves are located in close proximity to the surgical site during spinal surgery. While surgeons take great care to protect these delicate structures, there is always a potential for nerve injury during surgery.
Symptoms of nerve damage can include pain, numbness, weakness, and tingling in the arms or legs. The severity of nerve damage can range from temporary to permanent. Temporary nerve damage usually resolves on its own over time, while permanent nerve damage may result in long-term disability.
Intraoperative monitoring techniques, such as electromyography (EMG), are often used during spinal surgery to monitor nerve function and help the surgeon avoid nerve injury.
Pain Management Issues
While the goal of spinal surgery is to relieve pain, some patients may experience persistent pain after surgery. This can be due to a variety of factors, including nerve damage, scar tissue formation, or underlying inflammation.
It’s important to have realistic expectations regarding pain relief after spinal surgery. While many patients experience significant pain reduction, it’s not always possible to eliminate pain completely.
Different pain management strategies are available to help manage post-operative pain, including medications (such as opioids, non-steroidal anti-inflammatory drugs, and nerve pain medications), physical therapy, and nerve blocks. It’s important to work closely with your doctor to develop a pain management plan that is right for you.
The potential for opioid dependence is a concern with long-term opioid use. Your doctor will carefully monitor your opioid use and explore alternative pain management options to minimize this risk.
Wound Healing Problems
Wound healing problems, such as slow healing or wound breakdown, can occur after spinal surgery. These problems are more common in patients with certain risk factors, such as smoking, diabetes, and poor nutrition.
It’s essential to follow your doctor’s post-operative wound care instructions carefully to promote proper wound healing. This includes keeping the incision site clean and dry, changing dressings as directed, and avoiding activities that could put stress on the wound.
Specific Risks Associated with Different Types of Spinal Surgery
In addition to the general risks outlined above, certain types of spinal surgery carry their own specific risks.
Discectomy
Recurrent Disc Herniation
Even after a discectomy, there is a possibility of the disc herniating again at the same level. This is more likely to occur if you have a pre-existing weakness in the disc or if you engage in activities that put excessive stress on your spine.
Annular Tear
The annulus is the outer layer of the disc. A discectomy can sometimes lead to further tearing of the disc annulus, which can cause pain and instability.
Laminectomy/Laminoplasty
Spinal Instability
A laminectomy involves removing a portion of the lamina, the bony arch that covers the spinal cord. If too much bone is removed, it can lead to spinal instability, which can cause pain and nerve compression.
Post-Laminectomy Syndrome
Some patients develop chronic pain and instability after laminectomy, a condition known as post-laminectomy syndrome. This can be a challenging condition to manage and may require further treatment.
Spinal Fusion
Non-Union (Pseudoarthrosis)
Spinal fusion involves joining two or more vertebrae together. If the bones do not fuse properly, it can lead to a condition called non-union or pseudoarthrosis. This can cause pain and instability and may require further surgery.
Adjacent Segment Disease
Spinal fusion can put extra stress on the vertebrae above and below the fused segment, leading to problems in those areas. This is known as adjacent segment disease and can cause pain, nerve compression, and the need for further surgery.
Hardware Failure
Spinal fusion often involves the use of screws, rods, or plates to stabilize the spine. These hardware components can sometimes break or loosen, requiring further surgery to repair or replace them.
Bone Graft Complications
Spinal fusion typically involves the use of bone graft to help the bones fuse together. Bone graft can be harvested from the patient’s own body (autograft) or obtained from a donor (allograft). Complications related to bone graft harvesting can include pain, infection, and bleeding at the harvest site.
Minimally Invasive Spinal Surgery (MISS)
While often presented as lower risk, minimally invasive spinal surgery still carries risks. These procedures involve smaller incisions and less tissue damage than traditional open surgery, but they also have their own unique set of potential complications.
Potential complications of MISS include incomplete decompression (failure to fully relieve pressure on the spinal cord or nerves) and nerve injury due to limited visualization. The longer learning curve for surgeons performing MISS may also increase the risk of complications in some cases.
Spinal Cord Stimulation (SCS)
Spinal Cord Stimulation (SCS) is a procedure used to manage chronic pain by delivering electrical impulses to the spinal cord. While it can be effective, it’s important to be aware of potential risks:
Lead Migration
The leads that deliver the electrical impulses can sometimes move from their intended location, reducing the effectiveness of the therapy and potentially requiring repositioning.
Infection
As with any implanted device, there is a risk of infection at the implant site.
Device Malfunction
The SCS device itself can malfunction, requiring repair or replacement.
Pain at the Implant Site
Some patients may experience pain or discomfort at the site where the device is implanted.
Factors That Can Increase the Risk of Spinal Surgery
Certain factors can increase the risk of complications after spinal surgery. It’s important to be aware of these factors and discuss them with your doctor.
Pre-existing Medical Conditions
Certain medical conditions can increase the risk of complications after spinal surgery. These conditions include:
- Diabetes
- Obesity
- Smoking
- Cardiovascular disease
- Compromised Immune System
- Osteoporosis
Age
Older patients may have a higher risk of complications after spinal surgery due to age-related changes in their bodies and a higher prevalence of pre-existing medical conditions.
Lifestyle Factors
Certain lifestyle factors can also increase the risk of complications after spinal surgery. These factors include:
- Smoking (smoking significantly impairs healing and fusion)
- Poor Nutrition
- Lack of Exercise
Previous Spinal Surgeries
Previous spinal surgeries can increase the complexity and risk of subsequent procedures due to scar tissue formation and altered anatomy.
Surgeon Experience
The experience and skill of the surgeon performing the spinal surgery can significantly impact the risk of complications. Choosing an experienced and qualified surgeon is crucial.
Minimizing Your Risk: What You Can Do
There are several steps you can take to minimize your risk of complications after spinal surgery.
Thorough Pre-operative Evaluation
A thorough pre-operative evaluation is essential to identify any potential risk factors and optimize your health before surgery. This evaluation should include a comprehensive medical history, physical examination, and imaging studies (such as MRI and CT scans).
