Abstract

Osteoporosis is a frequently accounting condition in an elderly-adult population that is associated with decrease in bone mass and disruption of bone architecture that finally results in a load bearing capacity decrease [1]. Pedicle screw fixation is a frequently employed technique for degenerative diseases and unstable traumatic injuries treatment however this type of surgery remains a challenge in patients with osteoporosis as far as loosening rate may exceed 50% in those cases [2]. Taking into account risks of implant instability in patients with poor bone quality it is essential to achieve a sufficient purchase of screws in bone to resist physiological loads and to provide sufficient stability for fusion formation. Several strategies were suggested to achieve an increase in pedicle screw fixation strength in patients with poor bone quality and the most frequently used are based on bone cement augmentation [3,4].
