Surgery has one primary goal, to halt the progression of scoliosis by using some type of spinal fusion. Successful surgery is considered when the scoliosis progression has been halted, however it has been increasingly recognized by scoliosis experts that this always doesn’t mean a healthy person. Things like physical appearance, pain levels, quality of life may be negatively affected by surgery. If surgery doesn’t achieve the desired outcome, option for further treatment can be limited.
