INTRODUCTION Pedicle screws are commonly employed to restore spinal stability and correct deformities. The Renaissance robotic system was developed to improve the accuracy of pedicle screw placement. PURPOSE In this study, we developed an intraoperative classification system for evaluating the accuracy of pedicle screw placements through secondary(More)
This purpose of this retrospective study is validation of an intraoperative robotic grading classification system for assessing the accuracy of Kirschner-wire (K-wire) placements with the postoperative computed tomography (CT)-base classification system for assessing the accuracy of pedicle screw placements.We conducted a retrospective review of(More)
The objective of this study was to investigate the risk of osteoporosis in patients with herpes zoster (HZ) infection using a nationwide population-based dataset. The Taiwan National Health Insurance Research Database was used to compare data between 11,088 patients aged 20 to 49 years diagnosed with HZ during 1996 to 2010 and a control group of 11,088(More)
The aims of this study were to investigate the risk of hip fracture and contributing factors in patients with erectile dysfunction(ED). This population-based study was performed using the Taiwan National Health Insurance Research Database. The analysis included 4636 patients aged ≥ 40 years who had been diagnosed with ED (International Classification of(More)
In this study, we aimed to investigate the risk of osteoporosis in patients with erectile dysfunction (ED) by analyzing data from the Taiwan National Health Insurance Research Database (NHIRD). From the Taiwan NHIRD, we analyzed data on 4460 patients aged ≥40 years diagnosed with ED between 1996 and 2010. In total, 17,480 age-matched patients without ED in(More)
A 44-year-old man presented with a 6-month history of intermittent occipital headaches. The patient had no history of cranio-facial trauma. The neurological examination was unremarkable. Cerebral angiography revealed the typical angiographic features of a developmental venous anomaly (DVA) in the left cerebellar hemisphere by showing dilated medullary veins(More)
Whether traumatic brain injury (TBI) is causally related to substance related disorder (SRD) is still debatable, especially in persons with no history of mental disorders at the time of injury. This study analyzed data in the Taiwan National Health Insurance Research Database for 19,109 patients aged ≥18 years who had been diagnosed with TBI during(More)
The aim of this study was to investigate osteoporosis risk in atopic dermatitis (AD) patients. This study included patients in the Taiwan National Health Insurance Research dataset. The population-based study included all patients aged 20-49 years who had been diagnosed with AD during 1996-2010. In total, 35,229 age and gender-matched patients without AD in(More)
This article describes factors affecting the accuracy of transpedicle screw placements performed with the Renaissance robot-guided system and reviews the relevant literature. Between January 2013 and January 2015, Renaissance robot-guided spinal surgery was performed in 125 patients at Kaohsiung Medical University Hospital in Kaohsiung, Taiwan. The(More)
