“…In agreement with other studies, we think this study further demonstrates the EOS 2D/3D scanners potential role as a reliable tool for measuring lower limb parameters in a pediatric population . While difficulties may arise due to the growth cartilages, resulting in longer processing times in those under 10 years old and may prevent full 3D reconstruction in under fours, they can be reliably carried out in the majority of children …”

“…[10][11][12][13] The reliability of this reconstruction method has been well studied, though limited reports describe its use with children. [14][15][16][17][18][19] We had several aims in this study. Firstly to find and examine the reliability of a method for quick, reliable assessment of bone age for our database of stored EOS 2D/3D images.…”

The aim of this study was to evaluate bone age and its correlation with the lower limbs' developing skeletal anatomy during growth. 1005 children and young adults were evaluated for bone age and 14 different parameters measured on lower-limb reconstructions from radiological examinations carried out with an EOS 2D/3D system in the course of routine orthopedic indicated diagnostic practice. Cervical vertebral morphology evaluation for bone age using the Hassel-Farman method, which describes six stages of maturity, was selected. Intra- and inter-observer reliability tests for this method, and for the EOS 3D reconstructions were performed. Statistical analysis were performed using Spearman correlation, multiple linear regression, and t-test. The intra- and inter-observer reliability of the Hassel-Farman method and the EOS 3D lower-limb reconstruction were found to be excellent. Interestingly one bone age stage could include individuals across a 12.1 year range, and conversely individuals of the same calendar age could be of one of 3.2 different bone age stages. In the prepubertal age groups all six bone stages could be observed. Bone age revealed a stronger relationship, lower standard deviations with groups and proved to be a better discriminating variable than the calendar age by collodiaphyseal angle, femoral, and tibial torsion, femorotibial rotation, and mechanical tibiofemoral angle. Bone age is an indicator of skeletal maturity and may more accurately describe the growth of some lower limb parameters. As a result we suggest the consideration of bone age when evaluating lower-limb biomechanic-anatomical parameters. © 2016 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

“…The results suggest high accuracy and similar values as obtained from CT with the benefit of reduced radiation [3,5]. In fact, even pelvic parameters can be assessed [12]. Could this new technology enable us to look at the relation and the additive effect between femoral anteversion and acetabular version during stance?…”

“…A recent report suggested that inter-individual differences in hip anatomy may increase the risk of developing idiopathic osteonecrosis of the femoral head. 7 Hip anatomy is known to vary by age, 8 gender, and ancestry, 9 all of which have also been associated with altered risks of osteonecrosis. 2,3,5,10,11 Because hip anatomy can be readily assessed by plain x-ray which is universally available, we evaluated the association of hip anatomy with the development of osteonecrosis in children treated for ALL.…”

Osteonecrosis is a debilitating toxicity associated with acute lymphoblastic leukemia (ALL) treatment. A recent report associated inter-individual differences in hip anatomy with the development of idiopathic osteonecrosis in adults. To evaluate the impact of hip anatomy on the development of therapy related osteonecrosis, we retrospectively evaluated the femoral neck-shaft angle, femoral neck offset, and lateral center-edge angle using x-rays of 18 osteonecrosis cases and 46 control children treated for newly diagnosed ALL on a single protocol. Despite adequate statistical power, we found no association between hip anatomy and osteonecrosis. Investigation of other factors contributing to ALL associated osteonecrosis is warranted.

Three-dimensional quantitative analysis of the proximal femur and the pelvis in children and adolescents using an upright biplanar slot-scanning X-ray system

Abstract: The EOS 2-D/3-D system proved to be a valuable method in the evaluation of female and male developmental changes in pelvic and lower limb anatomical parameters, in normal individuals younger than 16 years of age.
