There are several ways to correct spinal deformities such as scoliosis and kyphosis:
Posterior – from the back of the spine as you lie on your stomach (most frequently performed for idiopathic adolescent scoliosis)
Anterior – from the front of the spine through the side of your chest or abdomen
Both posterior and anterior – a combination of both posterior and anterior techniques, generally recommended for curves that are very severe and stiff, or when previous attempts at fusion have failed.
