Comparative Study
Lumbar range of motion: reliability and validity of the inclinometer technique in the clinical measurement of trunk flexibility.
This study examines the reliability and validity of measuring lumbar range of motion with an inclinometer. ⋯ The noninvasive inclinometer technique proved to be highly reliable and valid, but the measurement technique for extension needs further refinement.

An analysis was made of the self-reported medical histories of patients with peripartum pelvic pain. ⋯ It is hypothesized that peripartum pelvic pain is caused by strain of ligaments in the pelvis and lower spine resulting from a combination of damage to ligaments (recently or in the past), hormonal effects, muscle weakness, and the weight of the fetus.

Andreas Vesalius was born in Brussels on December 31, 1514. After having spent some disappointing years at the Universities of Louvain and Paris, he graduated as Doctor of Medicine in Padua on December 5, 1537. The next day he was appointed as a teacher of both human anatomy and surgery. ⋯ Like Copernicus, Kepler, Bruno, and Galileo, Vesalius was one of the initiators of the new science. The tables of osteology and of the spine in Fabrica and Epitome are most impressive. Much of the nomenclature used for the spine today can be credited to him.

A prospective blind study compared three new technologies to assess back pain. ⋯ The diagnostic accuracy of thermography in recent onset low back pain does not support its use. Among those simulating normality or low back pain, triaxial dynamometry and spinoscopy have greater diagnostic accuracy than does a single clinical evaluation. However, for an individual, the inaccuracy that remains limits the use of triaxial dynamometry or spinoscopy for diagnosis in recent onset low back pain.

This study evaluated the anatomic relationship between the vertebral artery foramen and the posterior midpoint of the cervical lateral mass using cervical spine specimens. ⋯ The present study indicated that there is no risk of damaging the vertebral artery if a screw is directed perpendicular to the posterior aspect of the lateral mass at C3-C5 and 10 degrees lateral to the sagittal plane at C6 starting at the midpoint of the lateral mass.
