LEG LENGTH DISCREPANCY IN ADOLESCENT IDIOPATHIC SCOLIOSIS

ABSTRACT Objective The objective of this study is to evaluate leg length discrepancy in adolescent idiopathic scoliosis. Methods A retrospective study of 80 subjects with adolescent idiopathic scoliosis (AIS) was conducted. The inclusion criteria were patients aged 10 to 18 years old with posteroanterior (PA) and lateral full-length radiographs. The exclusion criteria were patients subjected to surgery or orthotic treatment, those with other spinal disease, and those with poor quality x-rays. The parameters evaluated were: age, sex, Risser stage (RS), triradiate cartilage (TC), scoliotic curvatures, differentiated according to Lenke classification, sagittal (SB) and coronal balance (CB), and leg length discrepancy, which was assessed through the difference between the femoral heads (LLD) and through the assessment of pelvic obliquity (PO). Results The majority of patients with AIS demonstrated a mild LLD (
