Correlation of 360° torso surface topography (ST) indices to 3D skeletal deformity radiographic measures in adolescent idiopathic scoliosis (AIS)

Eligibility

Inclusion Criteria:
  • Children with AIS (all curve types)
  • Risser sign of less than or equal to 3 at the time of enrollment
  • Cobb angle between 11° and 40°

Exclusion Criteria:

  • Children with a non-AIS diagnosis (e.g. neuromuscular, congenital, or syndromic etiology)
  • Children with a significant limb length inequality (i.e. > 2 cm)
  • Children with AIS who have previously treated with a brace or surgical intervention
  • Children with AIS who have comorbidities that do not allow them to stand without support (e.g. balance challenges)

Description

Surface topography allows the 3D mapping of the torso using data from standard photographs. For children with AIS, improved surface topography indices validated against a 3D in-vivo skeletal model and evaluated for clinical relevance have the potential to give clinicians reliable and quantifiable non-radiographic information that they currently lack. Successful detection of scoliosis progression between two time points using torso surface topography will achieve the goal of reducing radiation exposure, as only those who present with detected progression would require follow-up x-rays. This fits within the overarching project objective to reduce X-ray exposure of AIS patients during routine monitoring and evaluation of the scoliotic deformity.

The purpose of this study is to correlate 3D torso surface indices (collected using a newly developed surface topography system) with respective 3D skeletal indices (collected via the EOS Imaging platform) to help validate the use of non-radiographic methods alone in the detection and monitoring of scoliosis progression in children with AIS.
