Sixteen patients (modified group) received modified HPT combined with PSO, and 22 patients (control group) underwent traditional HPT combined with PSO.

No significant differences in surgical parameters were observed between the two groups. The total complication rate in the modified group (6.3%) was lower than in the control group (9.1%). At one-year follow-up, Cobb angles in the coronal and sagittal planes were maintained at 45.94\u2009\u00b1\u20092.91\u2005\u00b0 and 45.06\u2009\u00b1\u20091.88\u2005\u00b0, respectively, with an average height increase of 9.38\u2009\u00b1\u20090.72 cm in the modified group.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Both modified and traditional HPT combined with PSO are effective and safe.
