Abstract
An intervertebral support device may include upper and lower vertebral mounting fixtures to be respectively connected to an upper and a lower vertebra in a patient's spine. The device may further include a bias member for urging the upper and lower vertebral mounting fixtures together, and a bias adjuster connected to the bias member maintained in tension for adjusting the tension thereof. The bias adjuster advantageously allows a spinal surgeon installing the intervertebral support device to adjust the tension of the bias member during installation, as well as to re-adjust the tension post-operatively during follow-up visits to modify a patient's intervertebral mobility as needed.
