title: The sagital balance in idiopatic and neuromuscular scoliosis.
abstract: OBJECTIVE
  To describe and compare the distribution of spinopelvic parameters (SPP) in a Brazilian population with idiopathic scoliosis (IS) and neuromuscular scoliosis (NMS), and evaluate the association between pelvic incidence (PI) and lumbar lordosis (LL).
  
  
  METHODS
  Medical records investigation was performed. Sagital balance angles were measured in patients with neuromuscular and idiopathic scoliosis.
  
  
  RESULTS
  IS SAMPLE MEANS (IN DEGREES): PI 55.55; Sacral Slope (SS) 45.35; Pelvic Tilt (PT) 10.19; Lumbar Lordosis (LL) 43.48; and Thoracic Kyphosis (TK) 32.10. In NMS: PI 53.77; SS 42.31; PT 11.46; LL 49.46; and TK 45.69. No statistically significant differences in PEP distribution were found between the two types of scoliosis (p=0,057). The association between pelvic incidence and lumbar lordosis is low among idiopathic scoliosis (R=0,074) and neuromuscular scoliosis (R=0,274).
  
  
  CONCLUSIONS
  PEP measurements in a Brazilian population of idiopathic scoliosis and neuromuscular scoliosis patients are similar to those in the international literature and do not differ statistically between them. The association between LL and PI could not be assessed in this study. Level of Evidence IV, Case Series.
