Abstract
A fenestrated pedicle screw augmented with bone cement showed increased pullout strength for both thoracic and lumbar vertebrae within severely compromised bone mineral density when compared with standard pedicle screws without PMMA. By using a fenestrated screw, it was possible to inject an exact amount of cement, localized around the screw tip, with decreased risk of epidural leakage. A total of 30 elderly patients with 38 symptomatic VCFs were enrolled in a prospective study of fenestrated pedicle screw (FPs).Clinical outcomes were measured pre- and postoperatively using the visual analogue scale (VAS), Oswestry Disability Index (ODI) and ambulatory status (AS). Most of outcomes were improved post-operatively and at followup visits. So, elderly patients with symptomatic VCFs had rapid, significant, and sustained improvements in back pain, back function, and quality of life following FPs augmented with cement injection
