Osteoporotic fractures are very common and represent an enormous unmet medical need. Our group has previously reported that addition of rTNF to the fracture site promotes fracture healing in C57/BL6 mice (Glass et al. PNAS 2011). Using a murine fracture model of endochondral healing, we observed that local addition of rTNF only accelerates fracture repair if administered within the first 24 h following injury. The optimal therapeutic dose is 1 ng. TNF is firs...

Zoledronic acid has been shown to reduce the risk of fractures and improve bone mineral density (BMD) in osteoporosis vs placebo. This study compared changes in BMD in patients with osteoporosis treated with zoledronic acid vs alendronate. BMD at the lumbar spine and total hip pre- and post-bisphosphonate were recorded for 65 patients with osteoporosis (T score ≤−2.5) from retrospective analysis of DEXA scans. 35 patients received annual 5 mg IV zoledronic...
