What is What Is the Impact of Scoliotic Correction on Postoperative Shoulder Imbalance in Severe and Rigid Scoliosis about?

## Background: Although recent studies have investigated the risk factors for psi, few studies have focused on the impact of scoliotic correction on postoperative shoulder imbalance (psi), especially in severe and rigid scoliosis (srs). the purpose of the study was to study the effect of scoliotic correction on psi in srs. ## Methods: The preoperative, postoperative, and minimum 2-year follow-up radiographs of 48 consecutive patients with srs who underwent posterior spinal fusion surgery were evaluated. we regarded radiographic shoulder height (rsh) as a shoulder balance parameter and divided the patients into improved and aggravated groups of psi from pre- to post-operation and from post-operation to last follow-up, respectively. in addition, patients were divided into nine groups based on the observed changes in psi after surgery and at follow-up, and the correction rate ratios were calculated among the groups. independent samples t test and chi-squared test were performed between the improved and aggravated groups of psi. ## Results: After surgery, the proximal thoracic curve (ptc) flexibility (p = 0.040), correction rate of the main thoracic curve (mtc) (p = 0.010), and cobb an
