Preoperative Teriparatide Use on Insertional Torque of Pedicle Screws for Lumbar Fusion Surgery
Effect of 1 Month Preoperative Teriparatide Use on the Insertional Torque of Pedicle Screws for Lumbar Fusion Surgery
About This Trial
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.
Who May Be Eligible (Plain English)
Who May Qualify:
- Patients must be osteoporotic: baseline BMD assessed by DEXA scan must be considered as osteoporotic (\>2.5 SD from sex-matched young adult, or previous vertebral and/or femoral fractures) and indicated for spinal fusion surgery
Who Should NOT Join This Trial:
- Paget disease of bone, high laboratory tests for serum alkaline phosphatase or calcium, previous radiation treatment or fusion surgery to lumbar spine, bone tumors, metabolic bone disease, and hypersensitivity to teriparatide
Always talk to your doctor about whether this trial is right for you.
