Placement of lumbar fixation screws using the cortical bone trajectory is a novel and potentially valuable technique. In this chapter, we discuss the current literature on clinical outcomes and biomechanical properties of the cortical bone trajectory. We examine indications for which this trajectory may be beneficial compared to a traditional pedicle ...

Cortical bone measurements in Turner's syndrome
American Journal of Physical Anthropology, 1977AbstractCortical bone width measurements taken at midshaft on the second metacarpal were obtained from 156 hand X‐rays of 80 karyotypically documented individuals with Turner's syndrome age 1 to 25 years. Total shaft width, medullary width, cortical width and percent cortical area were grouped by bone age and compared with normal female standards ...

Quantitative radiology: radiogrammetry of cortical bone
The British Journal of Radiology, 1976Based on personal experience and data in the literature, an overview is given of radiogrammetry of cortical bone of the second metacarpal. There is a within- and between-observer error which amounts respectively to 1.2 and 1.5% for the outer diameter and 4.8 and 6.4% for the inner diameter.

Eighty percent of the skeleton consists of cortical bone, while twenty percent is trabecular; the percentages are of the wet or dry weight of the bone and do not include the soft-tissue or marrow spaces that make up part of the bone, particularly the trabecular or spongy bone.
