All patients underwent corrective surgery using the sandwiched bar and screw fixation system. Data were collected on demographic characteristics, operative time, length of hospital stay, Haller Index (HI), and postoperative complications. The effectiveness of the procedure was evaluated based on changes in the HI. Statistical analyses were performed using paired t\u2010tests to compare preoperative and postoperative HI values, and multivariate linear regression was used to identify factors associated with postoperative outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of the 39 consecutive patients, 12 (30.8%) had symmetric PC, 10 (25.6%) asymmetric PC, and 17 (43.6%) had PC with an excavatum complex.
