2018
Background: Backing out and failure of pedicle screws in patients with osteoporosis is becoming a big problem due to wide use of these screws nowadays. Purpose: The aim of this study is to evaluate the purchase of fenestrated pedicle screws augmented with cement in patients with osteoporosis. Study Design: This was retrospective observational study. Patients and Methods: From May 2015 to January 2016, 25 patients with a poor bone stock condition underwent posterior fixation by fenestrated pedicle screws and cement augmentation. Assessment of pain improvement was done by visual analogue score (VAS) score while the long-term clinical outcome was assessed using Oswestry low back disability questionnaire (Oswestry disability index [ODI]). Implant stability was evaluated by plain radiography. Complications were evaluated in all cases. Results: All patients were followed up clinically and radiographically for a mean age of 24.84 months. There was a significant reduction in pain and improvement of the quality of life as detected using VAS scores and ODI questionnaire consecutively ( P Conclusion: Augmentation of fenestrated screws with cement provided effective and lasting purchase in patients with osteoporosis. The only clinical complication strictly related to this technique was cement leakage.
