Rods placed in the back are based on how the spine is curved. Compression rods are placed on the outside of the curves and are used to compress, or shorten, the curve. Distraction rods are placed on the inner side of the curves, and are used to push out, or lengthen, the curves. People with scoliosis may require one or both types of rods, depending on what abnormal curvature is present. After surgery a patient may be placed in plaster casts for a few months to keep from moving the rods.
Patients usually require at least a few days in the hospital after surgery.
Full healing takes at least 12 to 18 months. This time allows the pieces of bone that are placed in the back to heal totally. During the healing process, strenuous exercise and contact sports should be avoided. Most other activities are encouraged as they speed healing. Remember that adolescence may be a difficult time, and many adolescents who undergo this kind of surgery feel discouraged and sad.
