“…Cosmetic disorder is one of the main reasons to treat Idiopathic Scoliosis patients (SOSORT Consensus) [ 1 ]. Shoulder balance (ShB) has been considered a characteristic of the deformity in idiopathic scoliosis [ 2 ]-[ 4 ]. According to Raso, this represents 75% of the perceived deformity of the trunk, together with asymmetry of the scapulae and shoulder girdle [ 2 ].…”

ObjectiveTo determine the validity of digital photography as an evaluation method for shoulder balance (ShB) in patients with idiopathic scoliosis.Material and methodsA total of 80 patients were included (mean age 20.3 years; 85% women). We obtained a full x-ray of the vertebral column and front and back clinical photography for all patients. For antero-posterior x-rays we measured the proximal thoracic curve angles (CPT). To evaluate radiological shoulder balance we calculated the clavicle-rib intersection angle (CRIA) and T1-tilt. For clinical photography we measured shoulder height angle (SHA), axilla height angle (AHA) and the left right trapezium angle (LRTA). We analyzed the reliability of the different photographic measurements and the correlation between these and the radiological parameters.ResultsThe mean magnitude of PTC, CRIA and T1-tilt were 19°, −0.6° and 1.4° respectively. Mean SHA from the front was −1.7°. All photographic measurements revealed an excellent-near perfect intra and inter-observer reliability in both photographic projections. No correlation was found between the ShB and the magnitude of the PTC. A statistically significant correlation was found between clinical balance of the shoulders and radiological balance (r between 0.37 and 0.51).ConclusionsDigital clinical photography appears to be a reliable method for objective clinical measurement of ShB. The correlation between clinical and radiological balance is statistically significant although moderate/weak.

“…Different methods have been proposed to assess shoulder imbalance [ 2 ]-[ 4 ]. Zaina et al, have developed a tool for routine clinical use (TRACE), consisting of photographs depicting different severities of four aspects of trunk deformity; shoulder, scapulae, hemithorax and waist.…”

“…The gold standard for diagnosis and subsequent curve surveillance remains standing full-column radiographs of the spine [3]. Radiographic images allow healthcare professionals to assess the dimensions of the deformity in both the coronal and sagittal planes, while quantifying the spinal curvatures by deriving Cobb angle measurements.…”

Purpose:In patients with adolescent idiopathic scoliosis (AIS), radiographic surveillance is the gold standard of assessing spinal deformity, but has negative long-term effects. The Formetric 4D surface topography system was compared to standard radiography as a safer option for evaluating patients with AIS.Methods:Fourteen volunteers with typical AIS patient stature had 30 repeated Formetric 4D measurements taken, and reproducibility was assessed. Sixty-four patients with AIS were then enrolled during routine clinic visits. Evaluation included standard radiographs and surface topography measurements. A comparison analysis was performed.Results:When assessing same-day repeated scans, a standard deviation of +/- 3.4 degrees for scoliosis curve measurements was determined, and the Reliability Coefficient (Cronbach) was very high (0.996). Cobb angles measured with the Formetric 4D differed from radiographic measurements by an average of 9.42 (lumbar) and 6.98 (thoracic) degrees, while the correlation between the two measurements was strong (95% confidence interval [CI]), 0.758 (lumbar) and 0.872 (thoracic) respectively.Conclusions:The Formetric 4D is comparable to radiography in terms of its test-retest reproducibility. Although this device does not predict curve magnitude exactly, the predictions correlate strongly with the Cobb angles determined from radiographs. It can be reliably used in the surveillance of patients with AIS.

“…Several landmarkbased indices of torso deformity were created as part of legacy systems for back torso imaging. These include the cosmetic score [14], the Posterior Trunk Symmetry Index score [16], the Integrated Shape Imaging System score [17], and the Quantec score [12]. These indices are the standard clinical measures of torso deformity that measure the relative lengths of the distances between landmark that are on the left and right of the torso.…”

This paper describes the use of structured splines indices for the clinical monitoring of torso deformity in scoliosis. Structured splines indices are computed from the distribution of points of maximal curvature (dominant points) of an object. The suitability and robustness of the indices for this application is assessed by ascertaining their robustness to inevitable torso shape variations due to sway and breathing and the variability in their values relative to existing clinical measures of deformity. To assess the consistency of these indices with other indices in use for this application, they were used to assess the relative information contents of the front and back of the torso. Results show that structured splines indices are more robust than existing clinical measures for monitoring torso deformity in scoliosis. Results also show that the scoliosis information content ratio of the back torso to the front torso is three to one.
