How Dangerous Is Scoliosis Surgery? Risks and Benefits

Scoliosis is a condition characterized by an abnormal sideways curvature of the spine, often appearing as an “S” or “C” shape. When the curve exceeds a certain degree, typically around 45-50 degrees, or progresses rapidly, surgical intervention may be considered to correct the curvature and prevent further progression. Like any major medical procedure, scoliosis surgery carries inherent risks, and understanding these potential challenges is important for individuals considering this treatment.

General Risks of Major Surgery

Anesthesia can lead to complications such as allergic reactions or respiratory issues. Patients may also experience excessive bleeding during or after the procedure, which could necessitate blood transfusions. Infection is another common concern, potentially occurring at the surgical site or becoming systemic. There is also a possibility of developing blood clots, such as deep vein thrombosis (DVT) in the legs, which can sometimes dislodge and travel to the lungs, leading to a pulmonary embolism (PE).

Scoliosis-Specific Surgical Risks

Scoliosis correction surgery, particularly spinal fusion, presents certain risks unique to the complexity of spinal procedures. Neurological damage, though uncommon, is a serious potential complication, ranging from temporary nerve issues to more severe outcomes like spinal cord injury, which could result in weakness, numbness, or even paralysis. Instrumentation complications can arise from the metal implants used to stabilize the spine, including hardware failure or the loosening and migration of screws.

Another concern is pseudoarthrosis, or non-union, which occurs when the spinal bones fail to fuse properly, potentially requiring additional surgery. Over time, some patients may develop adjacent segment disease, where the spinal segments directly above or below the fused area experience increased stress and degeneration. Flatback syndrome, characterized by a loss of the natural inward curve in the lower back, can also occur after fusion, leading to pain and difficulty standing upright. Some individuals may still experience persistent back pain, and in some cases, the achieved correction of the curve may be lost over time or not fully realized.

Factors Influencing Surgical Risk

Several factors can influence the overall risk profile of scoliosis surgery, varying from patient to patient. A patient’s age plays a role, as younger individuals often have better bone healing capabilities, while older patients may present with more co-existing medical conditions. The severity and type of the spinal curve also impact risk; larger, more rigid curves or atypical curvatures can make the surgery more technically demanding. A patient’s overall health, including the presence of other medical conditions such as heart disease, lung issues, or obesity, can increase surgical risks. The experience and specialization of the surgical team are also important, with highly experienced spinal surgeons generally associated with lower complication rates. Furthermore, the specific surgical approach used, such as anterior versus posterior fusion, or the adoption of minimally invasive techniques, can affect the potential for complications.

Minimizing Risks and Enhancing Safety

Medical teams employ various measures to minimize the risks associated with scoliosis surgery and enhance patient safety. A thorough pre-operative evaluation is conducted, involving a comprehensive medical history review, physical examinations, and detailed imaging to assess the patient’s condition and identify potential risks. This evaluation also includes careful surgical planning, sometimes utilizing 3D imaging. During the procedure, intra-operative neuromonitoring, such as evoked potentials, is used to continuously monitor spinal cord function in real-time, allowing surgeons to detect and address any changes promptly. Blood management strategies, including cell salvage and the use of anti-fibrinolytic agents, are implemented to reduce blood loss and the need for transfusions. Infection prevention protocols are strictly followed, involving prophylactic antibiotics administered before surgery and maintaining sterile techniques throughout the procedure. Post-operative care, which includes pain management, early mobilization, and physical therapy, is also important for a smooth recovery and to prevent complications.

Long-Term Outcomes and Quality of Life

For many patients, scoliosis surgery yields significant long-term benefits, particularly in correcting severe curves and preventing their progression. The procedure often leads to improved posture, better balance, and a reduction in pain. Patients frequently report an overall improvement in body image and self-esteem following surgery. Many individuals are able to return to most normal activities and sports after recovery. The benefits of scoliosis surgery often lead to a significant improvement in patients’ long-term health and overall quality of life.
