Background Transpedicular screws are a common adjunct for lumbar spine fusion. Accurate screw placement to prevent neurological injury has been the subject of many studies. The adoption of spine neuronavigation has shown a significant decrease in screw malposition morbidity. We aim to evaluate the accuracy of pedicle screw insertion using intraoperative CT-guided navigation in lumbar spondylosis. Methods We reviewed a prospective registry-based cohort study. This included patients who underwent transpedicular screws insertion for lumbar spondylosis under intraoperative CT-guided navigation (iCT-Nav) and compared it to another group operated using conventional fluoroscopy (FS) over one year. In addition, the correlation between clinical outcome using the visual analog scale (VAS) and short 12 physical component scores (SF-12 PCS) and hospital stay was reported. Results Fifteen patients were included in the iCT-Nav group compared to 42 patients in the FS group. The median age of the iCT-Nav group was 59.3 years old (27-76 years) versus 45 years old (20-60 years) in the FS group. The number of screws was 98 in the iCT-Nav group and 252 screws in the FS group. Based on more than 2-mm breach increments measured on CT images, lumbar pedicular screw placement accuracy was 100% in the iCT-Nav group and 86.9% in the FS group. None of the patients in the iCT-Nav group had to undergo any postoperative revisions. On the other hand, two patients of the FS group developed new postoperative symptoms related to displaced screws and required readmission and revision surgery. Conclusion In a commonly performed pedicular fixation in lumbar spondylosis, iCT-Nav has been shown to improve the accuracy of pedicle screw placement, hospital stay, and functional outcomes compared to FS.

Introduction: Quality Use of Medicines (QUoM) is of utmost importance regarding the safety and overall healthcare of the consumers/patients. This study aimed to explore the general usage pattern and attitude of the Makkah community about the safe use of medicines i.e. QUoM. Methods: Face to face interviews were done to administer questionnaires among patients from two hospitals and four primary care centers dealing with patients from rural and urban areas in the Holly Makkah region. Results: A total of 554 patients were enrolled while the majority of them were lived in urban areas (n=457,82%). Around 419 (76%) responder were females and 531(96%) were living with their family and had up to college education (n=174,31%). We found that most of the respondents were diabetic (185,33%) and hypertensive (n=172,31%). Most of the patients (207,37%) stated that they preferred to get drug information from healthcare professionals. Conclusion: This periodic mapping of appropriate medication usage among patients/consumers is indeed an important effort to explore issues on QUoM.
