Summary
This project aims to investigate any difference of insertional torque strength for
osteoporotic patients with preoperative 1-month teriparatide injections versus those without.
The increased insertional torque of pedicle screws during surgery after only 1 month of
teriparatide use has also been studied. However, the effect of teriparatide on vertebral body
bone mineral density (BMD) prior to and after fusion surgery has not been studied. The
effects on screw insertional torque has also not been studied via a randomized controlled
trial method.
