Introduction
Monitoring of scoliosis is traditionally done with radiographs, which can be associated with an increased risk of cancer secondary to multiple exposures over many years. This study investigated whether the findings from surface topography can be used to monitor scoliosis curves and how much this method affects outcome scores in patients with scoliosis. This study therefore had two subsets: (1) to investigate whether lateral asymmetry (LA) from ISIS2 surface topography can predict radiographic Cobb angle, providing an alternative non-invasive means of monitoring patients with scoliosis (LA and Cobb subset); and (2) to establish the relationships between the magnitude of the deformity in scoliosis, measured by Cobb angle on radiograph and volumetric asymmetry (VA) with the ISIS2 surface topography, and the patient perception of self-image and mental health, measured with SRS-22 scores (Cobb, VA, and SRS subset). In the LA and Cobb subset, 72 untreated patients with scoliosis (77 curves) with a Cobb angle of 55° or less were included in the study. They had clinical assessment, Cobb angle measurement taken from a standard radiograph, and surface topography done on the same day. A comparison of Cobb angle and LA was done. In the Cobb, VA, and SRS subset, 89 untreated patients with scoliosis were included in the study. They had clinical assessment, Cobb angle measurement of radiograph, and surface topography done on the same day along with SRS-22 questionnaires. A comparison correlation of SRS scores for function, pain, self-image, and mental health against Cobb angle and VA was undertaken. All statistical analysis was done with software R.Introduction
