Pivoted tensiometers (51) adapted for use in measuring tension in an intervertebral disc space and method of use are described. The tensiometer (51) includes a first longitudinal member (53) having a distal end portion (55) adapted for engaging a first vertebral surface, an intermediate portion (151), and a proximal handle portion (57) having an attachment point (117). A second longitudinal member (63) having a distal end portion (65) adapted for engaging a second vertebral surface, an intermediate portion (161), and a proximal handle portion (67) having an attachment point (119), the first and second longitudinal members being pivotally attached at a first pivot junction (71) between the proximal handle and intermediate portions of each longitudinal member is also included. A load cell (81) is attached to each of the attachment points (117,119) and is adapted to report a load corresponding to a change in distance between the attachment points. |
