Abstract: This study evaluates the surgical outcomes of hemivertebra excision using the eggshell osteotomy technique in patients with congenital scoliosis. A retrospective case series of seven patients was analyzed, measuring segmental and compensatory curves preoperatively, postoperatively, and at final follow - up. The results demonstrated significant initial corrections in segmental coronal curvature and kyphosis; however, long - term outcomes varied, with some patients showing progression. Continuous monitoring is crucial for managing deformity progression and optimizing treatment plans. The eggshell osteotomy technique is effective for immediate correction, but variability in outcomes highlights the need for personalized management.
