When Is Spinal Surgery Necessary for Scoliosis? A Patient’s Guide
Has your child recently been diagnosed with scoliosis? Or are you an adult experiencing back pain and wondering if scoliosis is the cause? You’re not alone. Scoliosis, a curvature of the spine, affects millions of people worldwide. While the word “scoliosis” can sound daunting, it’s important to remember that most cases don’t require surgery. There are many effective treatment options available, and the right approach depends on the individual’s specific situation.
This guide is designed to help you understand when spinal surgery becomes a necessary consideration for scoliosis and what to expect if it’s recommended. Based on decades of experience in spine care education, we aim to provide clear, understandable, and reassuring information to empower you and your family to make informed decisions about your health.
Understanding Scoliosis: More Than Just a Curve
Scoliosis is defined as an abnormal curvature of the spine. A healthy spine, when viewed from the back, should appear straight. In scoliosis, the spine curves to the side, often forming a “C” or “S” shape. It’s a condition that can affect people of all ages, but it’s most commonly diagnosed during childhood and adolescence. Understanding the different types of scoliosis is crucial for determining the best course of treatment.
Types of Scoliosis
Idiopathic Scoliosis
Idiopathic scoliosis is the most common type, accounting for approximately 80% of all cases. The term “idiopathic” means that the cause is unknown. While researchers have made progress in understanding the genetic factors that may contribute to idiopathic scoliosis, the exact trigger for the condition remains a mystery. Adolescent idiopathic scoliosis (AIS) is the most prevalent form, typically developing between the ages of 10 and 18, during the rapid growth spurts of adolescence.
Congenital Scoliosis
Congenital scoliosis is present at birth. It occurs when the vertebrae (the bones that make up the spine) don’t form properly during fetal development. This can result in vertebrae that are wedge-shaped, fused together, or missing altogether. Congenital scoliosis is often detected early in life, and its progression can be unpredictable. Early intervention is often necessary to prevent severe spinal deformities.
Neuromuscular Scoliosis
Neuromuscular scoliosis is caused by underlying neurological or muscular conditions, such as cerebral palsy, muscular dystrophy, spina bifida, or spinal cord injuries. These conditions can weaken the muscles that support the spine, leading to curvature. Neuromuscular scoliosis is often more severe and progresses more rapidly than idiopathic scoliosis. Treatment focuses on managing the underlying condition and stabilizing the spine.
Degenerative Scoliosis
Degenerative scoliosis typically develops in adults as a result of aging and spinal degeneration. Over time, the discs between the vertebrae can lose their height and become less supportive. This can lead to instability in the spine and the development of a scoliosis curve. Osteoarthritis, a common condition that affects the joints, can also contribute to degenerative scoliosis. Symptoms often include back pain, stiffness, and leg pain.
Progression of Scoliosis
Scoliosis can progress, especially during periods of rapid growth. In children and adolescents, the curve can worsen significantly during growth spurts. This is why regular monitoring and check-ups with a spine specialist are so important. In adults, scoliosis can also progress, although typically at a slower rate. Factors such as disc degeneration, ligament laxity, and muscle weakness can contribute to curve progression in adults.
Symptoms of Scoliosis
The symptoms of scoliosis can vary depending on the severity of the curve and the individual’s age. Common symptoms include:
- Uneven shoulders or hips
- Prominent shoulder blade
- Rib prominence
- Back pain (more common in adults)
- Fatigue
- Breathing difficulties (in severe cases)
In some cases, scoliosis may not cause any noticeable symptoms, especially in the early stages. This is why screening programs are often used in schools to detect scoliosis in children and adolescents.
Diagnosis of Scoliosis
The diagnosis of scoliosis typically involves a physical examination and imaging studies. The Adam’s Forward Bend Test is a common screening tool used to detect scoliosis. During this test, the patient bends forward at the waist, and the examiner looks for any asymmetry in the rib cage or back. If scoliosis is suspected, X-rays are taken to confirm the diagnosis and measure the severity of the curve.
The Cobb angle is the primary measurement used to determine the severity of scoliosis. It’s calculated by measuring the angle between the two most tilted vertebrae at the ends of the curve. A Cobb angle of 10 degrees or more is generally considered to be scoliosis. MRI (magnetic resonance imaging) may be used if neurological issues are suspected, such as spinal cord compression or nerve root impingement.
When is Surgery Considered? The Key Indicators
Surgery is not always necessary for scoliosis. In fact, most cases can be managed with non-surgical treatments. However, in certain situations, surgery may be the best option to prevent curve progression, reduce pain, and improve quality of life. The decision to proceed with surgery is based on a number of factors, including the Cobb angle, the patient’s age, the presence of symptoms, and the effectiveness of non-surgical treatments.
Cobb Angle Thresholds
The Cobb angle is a critical factor in determining whether surgery is necessary. Different thresholds are used for adolescents and adults.
Adolescents
In adolescents, surgery is typically considered when the Cobb angle is 40-50 degrees or greater and progressing. A curve of this magnitude has a high risk of progressing into adulthood, even after growth has stopped. Progressive curves can lead to significant spinal deformity, pain, and breathing difficulties. The goal of surgery is to stop the curve from progressing and prevent these long-term complications.
Adults
In adults, surgery is considered for significant pain, neurological symptoms, or curve progression that affects quality of life. Cobb angle thresholds may be less strict than in adolescents, focusing more on symptom management. Even a smaller curve can cause significant pain and disability in adults, especially if there is underlying spinal degeneration. The goal of surgery is to reduce pain, improve function, and prevent further curve progression.
Failed Non-Surgical Treatments
Surgery is usually a last resort, considered only after non-surgical treatments have been tried and have failed to provide adequate relief. Common non-surgical treatments include:
- Observation: Monitoring the curve to see if it progresses.
- Bracing: Wearing a brace to prevent curve progression (primarily used in adolescents). The purpose of a brace is to hold the spine in a straighter position, preventing the curve from worsening during growth. Bracing is most effective when used in conjunction with physical therapy.
- Physical therapy: Scoliosis-specific exercises to strengthen the muscles that support the spine.
- Pain management: Medications and injections to relieve pain.
Surgery is considered when these treatments are no longer effective in controlling pain or preventing curve progression. If the curve continues to worsen despite non-surgical treatment, surgery may be the best option to prevent long-term complications.
Pain and Neurological Symptoms
Severe, persistent pain that interferes with daily activities can be an indication for surgery, especially in adults. Scoliosis can cause pain by putting pressure on the spinal joints, muscles, and nerves. Neurological symptoms like numbness, tingling, or weakness in the legs or feet can also be an indication for surgery. These symptoms can occur if the scoliosis curve is compressing the spinal cord or nerve roots.
Impact on Organ Function
In very severe cases, scoliosis can affect lung or heart function, making surgery necessary. This is rare, but it can occur when the curve is so severe that it restricts the chest cavity, making it difficult to breathe or for the heart to pump blood effectively. Surgery can help to improve lung and heart function by correcting the spinal deformity.
Cosmetic Concerns
Cosmetic concerns can play a role, especially in adolescents. While the primary goal of scoliosis surgery is to address functional issues, surgery can also improve the appearance of the spine. Patients may be self-conscious about the unevenness of their shoulders or hips, or the prominence of their ribs. Surgery can help to correct these deformities and improve body image.
Types of Spinal Surgery for Scoliosis
Several types of spinal surgery are available for scoliosis, each with its own advantages and disadvantages. The best type of surgery for a particular patient depends on the severity of the curve, the patient’s age, and the presence of other medical conditions.
Spinal Fusion
Spinal fusion is the most common type of scoliosis surgery. It involves fusing vertebrae together to stop the curve from progressing. Bone grafts are used to promote fusion, and instrumentation (rods, screws) are used to stabilize the spine during the healing process. The goals of spinal fusion are to stop curve progression, reduce pain, and improve spinal alignment.
The procedure involves making an incision in the back to access the spine. The surgeon then prepares the vertebrae for fusion by removing the cartilage between them. Bone grafts, which can be taken from the patient’s own body or from a donor, are placed between the vertebrae. Rods and screws are then attached to the vertebrae to hold them in place while the bone grafts heal. Over time, the bone grafts will fuse the vertebrae together, creating a solid, stable spine.
Different Approaches
- Posterior Approach: The most common approach, involving an incision in the back.
- Anterior Approach: Involving an incision in the front, often used for curves in the lower spine.
- Thoracoscopic Approach: A minimally invasive approach using small incisions and a camera.
Vertebral Body Tethering (VBT)
Vertebral Body Tethering (VBT) is a newer, less invasive option for growing children with scoliosis. It involves attaching a flexible cord to the vertebrae on the convex side of the curve. The cord is tightened to correct the curve, allowing for continued growth and flexibility. VBT is not suitable for all patients, and it’s important to discuss the advantages and disadvantages with your surgeon.
The procedure involves making small incisions on the side of the chest. A flexible cord is then attached to the vertebrae on the convex side of the curve using screws. The cord is tightened to correct the curve, and the incisions are closed. VBT allows for continued growth and flexibility because it doesn’t involve fusing the vertebrae together. However, it’s not suitable for all patients, and it may not be as effective for severe curves.
Growing Rods
Growing rods are used for young children with severe scoliosis who are still growing. Rods are attached to the spine and lengthened periodically to accommodate growth. Fusion is delayed until the child reaches skeletal maturity. This allows the spine to grow while preventing the curve from progressing.
The procedure involves making an incision in the back to access the spine. Rods are then attached to the vertebrae above and below the curve. The rods are lengthened periodically, typically every six months, to accommodate growth. Once the child reaches skeletal maturity, a spinal fusion is performed to permanently stabilize the spine.
Osteotomies
Osteotomies are bone cuts used to correct severe deformities or restore spinal alignment. They are often used in adult scoliosis surgery to correct complex curves and improve spinal balance. Osteotomies can be used to realign the spine and reduce pain.
The procedure involves making incisions in the back to access the spine. The surgeon then makes cuts in the vertebrae to realign the spine. Rods and screws are used to stabilize the spine during the healing process. Osteotomies are complex procedures that require a high level of surgical skill. They are typically reserved for patients with severe spinal deformities who have not responded to other treatments.
What to Expect Before, During, and After Surgery
Undergoing spinal surgery for scoliosis can be a significant undertaking. Knowing what to expect before, during, and after surgery can help you prepare and feel more confident about the process.
Pre-Operative Preparation
Before surgery, you will undergo a thorough medical evaluation, including a physical exam, blood tests, and imaging studies. Your surgeon will discuss the risks and benefits of surgery with you and answer any questions you may have. You may also be asked to stop smoking, optimize your nutrition, and participate in pre-operative physical therapy to strengthen your muscles.
The medical evaluation is important to ensure that you are healthy enough to undergo surgery. Blood tests are used to check for any underlying medical conditions that could increase the risk of complications. Imaging studies, such as X-rays and MRI, are used to assess the severity of the scoliosis curve and plan the surgery. Smoking cessation is important because smoking can impair healing. Nutritional optimization can help to improve your overall health and reduce the risk of complications. Pre-operative physical therapy can help to strengthen the muscles that support the spine, which can improve your recovery after surgery.
The Surgical Procedure
The duration of the surgery will depend on the type of surgery being performed and the complexity of the curve. You will be under general anesthesia during the procedure. Intraoperative monitoring will be used to protect the spinal cord. A hospital stay is required after surgery.
General anesthesia will put you to sleep during the surgery so that you don’t feel any pain. Intraoperative monitoring involves using electrodes to monitor the function of the spinal cord during the surgery. This helps to ensure that the spinal cord is not damaged during the procedure. The length of your hospital stay will depend on the type of surgery you have and how quickly you recover.
Post-Operative Recovery
Pain management will be provided with medications and injections. Physical therapy will be started to regain strength and mobility. Bracing may be required for a period of time. Activity restrictions will be in place, including avoiding heavy lifting, bending, and twisting. Follow-up appointments with the surgeon will be scheduled. The typical recovery timeline is weeks to months.
Pain management is an important part of the recovery process. Your surgeon will prescribe medications to help manage your pain. Physical therapy will help you regain strength and mobility. Bracing may be required to support the spine while it heals. Activity restrictions are important to prevent complications. Follow-up appointments with the surgeon are necessary to monitor your progress and ensure that the fusion is healing properly.
Potential Risks and Complications
As with any surgery, there are potential risks and complications associated with scoliosis surgery. These include infection, bleeding, nerve damage, pseudarthrosis (failure of the fusion to heal), hardware failure, pain, and cosmetic issues. While complications are possible, they are relatively rare, and your surgical team will take every precaution to minimize your risk.
Living with Scoliosis After Surgery
Life after scoliosis surgery can be significantly improved. Most patients experience a reduction in pain and an improvement in their quality of life.
Long-Term Outlook
Most patients experience significant improvement in pain and quality of life after surgery. The goal is to stabilize the spine and prevent further curve progression. While you may not be able to do everything you could before surgery, you should be able to live a full and active life.
Activity Level
You will be able to resume most activities after surgery, but you may need to modify some activities to protect your spine. It’s important to stay active and maintain a healthy lifestyle. Your physical therapist can help you develop an exercise program that is safe and effective for you.
Ongoing Care
Regular follow-up appointments with the surgeon are necessary to monitor your progress. Physical therapy may be needed as needed. Pain management may be needed as needed.
Emotional Support
Scoliosis surgery can be a challenging experience. It’s important to seek support from family, friends, or support groups. Talking to others who have gone through the same experience can be helpful.
