Assesment [sic] of cement augmentation and screw trajectory on pedicle screw fixation in osteoporotic vertebrae
Pfeiffer, Ferris M., 1976-
Metadata[+] Show full item record
Internal fixation of osteoporotic spines for fracture or deformity is currently difficult, owing to failure at the bone- implant interface. This study aims to ascertain whether pedicle screw trajectory and pedicle cortex retention can independently significantly affect fixation strength in osteoporotic vertebrae.
