This technique was originally described to allow for shortening of the posterior column during correction of excessive thoracic kyphosis; however, its indications have since been expanded to other spine deformities such as adolescent idiopathic scoliosis (AIS). Its expanded role in deformity surgery has been met with controversy: proponents tout increased flexibility and better spinal correction in three planes, while detractors cite lack of ostensible clinical benefit and potential for more complications. Differences in surgical technique are also prevalent. In this manuscript, we review the surgical technique of PCOs, including the traditional PCO as well as a modified posterior column release (PCR). Additionally, the controversy over when this technique should be utilized is further explored through summation of current literature on PCO outcomes.</p> ER -
