The Torsion Meter: A Critical Review

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° and measured with a torsion meter by three investigators. One hundred forty-four errors...

Zusammenfassung:	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° and measured with a torsion meter by three investigators. One hundred forty-four errors were made in the 351 measurements, of which >92% were within ±5°. We concluded that use of the torsion meter is an effective way to measure vertebral rotation.
