A novel bone cement injector augments Chinese osteoporotic lumbar pedicle screw channel: a biomechanical investigation

Suochao Fu et al.

Summary: This study aimed to create and test a series of pedicle injectors with different numbers of holes for the augmentation of pedicle screw among osteoporotic lumbar pedicle channel. The results showed that 4-hole and 6-hole sheath augmented pedicle screws had similar effects to the straight pore injector. However, the 8-hole injector had relatively lower pull-out strength, and the straight pore injector had risks of cement leakage and solidification near the screw head.

Vertebral compression fractures: Still an unpredictable aspect of osteoporosis

Fatma Yesim Kutsal et al.

Summary: Vertebral compression fracture is a common fragility fracture associated with osteoporosis, and patients with this type of fracture are at high risk for additional fractures. Diagnostic methods include clinical evaluation, imaging, and laboratory tests, with screening and treatment of high-risk individuals being cost-effective.
