Potential risks of using cement-augmented screws for spinal fusion in patients with low bone quality

Dramatic increases in the average life expectancy have led to increases in the variety of degenerative changes and deformities observed in the aging spine. The elderly population can present challenges for spine surgeons, not only because of increased comorbidities, but also because of the quality of their bones. Pedicle screws are the implants used most commonly in spinal surgery for fixation, but their efficacy depends directly on bone quality. While PMMA-augmented screws represent an alternative for patients with osteoporotic vertebrae, their use has raised some concerns due to the possible association between cement leakages (CLs) and other morbidities.
