Lateral cephalometric radiograph is a radiograph of the head taken with the x-ray beam perpendicular to the patient's sagittal plane. Natural head position is a standardized orientation of the head that is reproducible for each individual and is used as a means of standardization during analysis of dentofacial morphology both for photos and ...
It is a common measurement of scoliosis. The Cobb angle is also the preferred method of measuring post-traumatic kyphosis in a recent meta-analysis of traumatic spine fracture classifications. [ 5 ]
Pelvimetry is the measurement of the female pelvis. [1] It can theoretically identify cephalo-pelvic disproportion, which is when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. However, clinical evidence indicate that all pregnant women should be allowed a trial of labor regardless of pelvimetry ...

Digital Motion X-ray is considered the most accurate method. Upright magnetic resonance imaging, supine magnetic resonance imaging, CT scan, and flexion and extension x-rays may also be used but are far less accurate and have a much higher potential for false negatives. The measurements to diagnose craniocervical instability are:
Goniometer made by Develey le Jeune in Lausanne, late 18th–early 19th century. A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. The term goniometry derives from two Greek words, γωνία 'angle' and μέτρον 'measure'. [1]
The first atlas published in 1898 by John Poland consisted of x-ray images of the left hand and wrist. [6] Since then, updated atlases of the left hand and wrist have appeared, [ citation needed ] along with atlases of the foot and ankle, [ 7 ] knee, [ 8 ] and elbow. [ 9 ]
[1] [2] However, the terms lordosis and lordotic are also used to refer to the normal inward curvature of the lumbar and cervical regions of the human spine. [3] [4] Similarly, kyphosis historically refers to abnormal convex curvature of the spine. The normal outward (convex) curvature in the thoracic and sacral regions is also termed kyphosis ...
