Scoliosis is a condition where the spine develops an atypical sideways curvature. While it can affect individuals of any age, it is most frequently identified in childhood or early adolescence, particularly between 10 and 15 years old. Approximately 2-3% of the population in the United States is affected. For some, surgery becomes a consideration to address the curvature. Modern surgical techniques have improved safety, but understanding risks and benefits is important.
Understanding Surgical Risks
Scoliosis surgery, often involving spinal fusion, carries potential complications, similar to any major surgical procedure. A rare but serious risk is paraplegia, which is the loss of movement and sensation in the lower body. This outcome highlights the delicate nature of spinal procedures.
Excessive blood loss is a risk during scoliosis surgery, sometimes requiring transfusions. Infections can also occur at the surgical site or elsewhere in the body. These can manifest days to years later and may require additional medical intervention.
Hardware complications are also possible, as the surgery often involves implanting rods, screws, or other devices to straighten and stabilize the spine. These can include hardware loosening, breakage, or even corrosion over time, which may necessitate further surgery. Pseudoarthrosis, or the failure of the spine to fuse properly, is another potential complication. This can lead to continued progression of the curve or persistent pain and may require revision surgery. General anesthetic risks, such as adverse reactions to medications, are also present.
Factors Influencing Surgical Safety
Several variables play a role in determining the safety and outcome of scoliosis surgery. A patient’s age and general health are influential factors. Older adults with degenerative scoliosis, for instance, may face increased risks due to existing medical conditions like smoking, obesity, or diabetes. The severity and flexibility of the spinal curve also impact the surgical approach.
The experience and specialization of the surgeon are significant. Surgeons who frequently perform scoliosis procedures often have a deeper understanding of the complex spinal anatomy and precise techniques required. The specific surgical technique chosen, such as posterior spinal fusion (PSF) or vertebral body tethering (VBT), also contributes to the safety profile. The medical facility’s resources, including advanced monitoring systems and specialized care units, can enhance patient safety. These elements are considered during preoperative evaluation to tailor the safest and most effective treatment plan.
Life After Scoliosis Surgery
The period immediately following scoliosis surgery typically involves a hospital stay for monitoring and pain management. Most patients remain hospitalized for about four to seven days. During this initial phase, patients are encouraged to begin moving, often as early as the first day after surgery, with assistance from medical staff. Pain management strategies are put in place, often starting with intravenous medications and transitioning to oral medications.
After discharge, home recovery begins, with an initial two to four weeks focused on limited activities like walking, dressing, and bathing. Full recovery can take six months to a year, depending on the original curve’s severity. Physical therapy and rehabilitation are important for regaining strength, flexibility, and proper posture. Patients should avoid bending or twisting the spine, lifting heavy objects, and high-impact sports for several months to allow proper fusion. Long-term follow-up monitors fusion and spinal health; while a fused spine has reduced flexibility, many patients adapt and maintain sufficient daily mobility.
When Surgery Becomes an Option
Scoliosis surgery is a treatment option considered when the potential benefits of correcting the spinal curvature outweigh the associated risks. Generally, surgery is recommended for individuals with severe curves, typically those measuring 45-50 degrees or more by the Cobb method. For growing children, surgery may be considered when a curve is greater than 40-45 degrees and shows signs of progression. This intervention aims to halt further progression and provide correction.
Surgery may also be considered when scoliosis causes significant pain unresponsive to conservative treatments. Severe spinal curves can compromise lung function by limiting chest movement; surgery can improve lung capacity and ease breathing, though full recovery may take time. The decision to proceed with surgery is a collaborative discussion between the patient, their family, and the healthcare team, weighing the individual’s condition and treatment goals.
