Evaluation of the Factors Affecting the Loss of Lumbar Lordosis in Surgical Treatment of Patients with Adolescent Idiopathic Scoliosis Using Segmental Instrumentation

Abstract

Background: The identification of independent factors affecting the loss of lumbar lordosis can facilitate programmed surgery in adolescent idiopathic scoliosis (AIS) patients especially with considering the importance of sagittal characteristics. Objectives: This study aimed to investigate the factors affecting the amount of the loss of lumbar lordosis in surgical treatment of the patients with AIS using segmental instrumentation. Methods: In this study which was conducted in three years, 91 AIS patients who underwent segmental instrumentation were studied and 63 patients remained in the study according to the inclusion criteria. All patients' information was recorded on admission in separate forms and radiography results were coded and archived before the surgery for more evaluation. All patients were subject to standing whole spine radiograph again 12 months after the surgery. Ultimately, the information was put into predetermined forms and was used for a statistical analysis after the completion of forms.
