  • First Online:
Essential Measurements in Pediatric Musculoskeletal Imaging

Abstract

This chapter is intended to provide a quick guide to the musculoskeletal measurements provided by EOS imaging and their interest in pediatric musculoskeletal pathology.

This kind of imaging, more than any other radiological technique, allows a wide variety of musculoskeletal measurements with a high grade of precision.

The measurements are obtained in physiological orthostatic conditions and are made on 2D biplanar images and 3D modeling.

An introduction will briefly explain the physical principles of EOS imaging and its most common applications in the pediatric field.

The second section is dedicated to the measurements that can be obtained for the pelvis (pelvic incidence, sacral slope, pelvic tilt, pelvic obliquity, axial rotation of the pelvis) and the spine (coronal balance, C7—central sacral line, Cobb’s angle, lateral flexion, sagittal vertical axis, CAM plumb line, spino-sacral angle, thoracic kyphosis, lumbar lordosis). The measurements of the spine can be obtained with two different types of references, with respect to the radiological plane or to the anatomical plane of the patient’s pelvis.

The third section of the chapter is dedicated to the measurements of the lower limb (femoral mechanical axis length, tibial mechanical axis length, functional length of the lower limb, anatomical length of the lower limb, femoral head diameter, femoral offset, femoral neck length, neck/shaft angle, femoral mechanical angle, tibial mechanical angle, mechanical tibiofemoral angle, hip-knee-shaft angle, femoral torsion angle, tibial torsion angle, femorotibial rotation, sagittal femorotibial angle).
