Abstract

Background. Idiopathic scoliosis is a three-dimensional deformity of the spine. The measurement of vertebral axial rotation is one of the most important parameters in the assessment of a scoliotic curve. Bunnell proposed a device — scoliometer in order to measure the angle of trunk rotation (ATR). Scoliometer has not been described in polish scientific literature. Material and methods. 50 patients (65 scoliotic curves) were examined with Bunnell scoliometer. In the forward bending test position the scoliometer was applied to the surface of the back in the region of maximum deformity, with its „zero” over spinous processes. The exam was made by four independent observers: three senior students of physiotherapy and one orthopaedic surgeon experienced in scoliosis management. One author performed the exam three times. lnterobserver and intraobserver agreement were checked with ANOVA. Rib hump height was measured in millimetres and the correlation with the angle of trunk rotation was calculated. Results. lnterobserver agreement revealed high concordance of measurements (ANOVA, p<0,01). Non-experienced observers demonstrated results parallel to those of an experienced specialist. lntraobserver agreement was also found very high (ANOVA, p<0,01). Strong positive correlation between the rib hump height measurement with a goniometer and the angle of trunk rotation measurement with a scoliometer was found (r=0,92, p<0,05) in thoracic curves (n=30). Conclusion. Scoliometer can be recommended for standard use in the checking of children and adolescents examined for scoliosis. Non-experienced paramedicals can correctly use the device.

Abstract

Introduction. Changes in spinal geometry should be assessed in three planes, and accounting for the movement of spinous processes. An assessment of the angle of trunk rotation allows for early and non-invasive detection of scoliosis and its prevention.
Purpose. The purpose of this study was to assess the angle of trunk rotation (ATR) in the population of 10-year-old primary school children in Poznań.
Materials and methods. The participants included 1533 children aged 10 years (759 girls and 774 boys). The ATR was measured with the Bunnell scoliometer at three levels of the spine: Th1-Th4, Th5-Th12, Th12-L4. On the basis of the measurements conducted in this study, a group of children with ATR at 0, 1-3˚, 4-6˚ and ≥ 7˚ (including rotation to the left and to the right) was identified.
Results: The lowest values of ATR in both groups (boys and girls) were found at the level of Th1-Th4 with ATR ≥ 7˚ occurring in 0.2% of the participants. 4% of all participants also presented with a clinical suspicion of lateral curvature of the spine. Values of the ATR measured at the Th5-Th12 and Th12-L4 levels increased considerably. At the Th level of the spine, 10% of the participants presented with a clinical suspicion of scoliosis, and the diagnosis was confirmed for 2.5% of all primary school children. At the lowest level of the spine, 9% of the participants were identified as being at an increased risk of scoliosis, and 2.7% of children exhibited an ATR ≥ 7˚.
Conclusions:
1. The highest angle of trunk rotation (ATR ≥ 7˚) was found in girls at the Th5-12.level of the spine. Both genders exhibited primarily rotation to the right.
2. Scoliosis poses a significant diagnostic challenge in a school environment. If left untreated, it increases the risk of pathological changes in the trunk and disease progression.
3. The Bunnell scoliometer allows for early and non-invasive assessment of the angle of trunk rotation, and should be permanently included in screening procedures.
4. Using appropriate instruments for posture assessment is necessary for diagnosing musculoskeletal disorders accurately.
