The torsion meter: a critical review

J Pediatr Orthop. Jul-Aug 1990;10(4):527-31.

Abstract

The purpose of this study was to determine how effectively the torsion meter measures vertebral rotation. Nine thoracic vertebrae from three disarticulated spines were individually rotated through an arc of 0-60 degrees and measured with a torsion meter by three investigators. One hundred forty-four errors were made in the 351 measurements, of which greater than 92% were within +/- 5 degrees. We concluded that use of the torsion meter is an effective way to measure vertebral rotation.
