Understanding Scoliosis and Traditional Surgery Techniques

Scoliosis, a medical condition marked by an abnormal sideways curvature of the spine, primarily affects children and adolescents, especially just before puberty. The curvature, diagnosed when it exceeds 10 degrees, can occur in any of the spine’s three major sections: cervical (neck), thoracic (chest and upper back region), and lumbar (lower back). The treatment strategy for adolescent idiopathic scoliosis hinges on the curvature’s degree at diagnosis and its anticipated progression, with options ranging from observation in mild cases to nonsurgical methods like bracing or surgical interventions such as spinal fusion surgery.

Traditional Surgery Techniques:

  • Spinal Fusion Surgery: The most common surgical intervention for more significant cases of scoliosis, spinal fusion, involves the welding of vertebrae together using bone chips. The alignment is maintained using hooks or screws and rods, allowing the spine to heal in the correct position. Typically, patients may need to stay in the hospital for three to five days and can usually return to school in four to six weeks. However, rare complications can include infection and spinal cord abnormalities or injury.
  • Instrumentation Systems: Modern surgical treatments for scoliosis have evolved to use more anchors to connect the rod and the spine, leading to better correction of the curvature and less frequent implant failures. Techniques include segmental pedicle screw constructs or hybrid constructs using pedicle screws, hooks, and wires.
