Preoperative Teriparatide Use on Insertional Torque of Pedicle Screws for Lumbar Fusion Surgery

NCT03770338 · Status: ACTIVE_NOT_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 192

No results posted yet for this study

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.
