The tensiometer has a disc space spreader (11) that enters a disc space and distracts the space upon rotation. A torque gauge engage the spreader, where spreader has a proximal portion (21) and a distal pedal portion (13) with upper and lower surfaces having a thickness T and a lateral surface having the width W such that the width is greater than the thickness. The gauge has a longitudinal beam fitted to a handle. An independent claim is also included for a method of measuring tension in an intervertebral disc space. |
