Final answer:
A straightening rod is used to "fix" curvature, such as in scoliosis, kyphosis, or lordosis. These rods are made of strong and flexible materials like titanium or stainless steel, and they are surgically attached to the spine to straighten and align the curvatures over time.
Step-by-step explanation:
The kind of rod used to "fix" curvature is called a straightening rod. It is commonly used in the process of orthopedic correction to treat conditions like scoliosis, kyphosis, or lordosis.
Straightening rods are usually made of a strong and flexible material such as titanium or stainless steel. These rods are surgically attached to the spine and are used to straighten and align the curvatures over time, allowing the spine to grow in a more normal position.
For example, in the case of scoliosis, the straightening rod is inserted into the spinal column along the length of the curved area and secured with screws at each end. As the patient grows, the rod can be lengthened or adjusted to gradually correct the curvature.
