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)
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)
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)
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)
BACKGROUND Osteoporosis and migraine are both important public health problems and may have overlapping pathophysiological mechanisms. The aim of this study was to use a Taiwanese population-based dataset to assess migraine risk in osteoporosis patients. METHODS The Taiwan National Health Insurance Research Database was used to analyse data for 40,672(More)
BACKGROUND Neuropathic pain in small-fiber neuropathy results from injury to and sensitization of nociceptors. Functional prostatic acid phosphatase (PAP) acts as an analgesic effector. However, the mechanism responsible for the modulation of PAP neuropathology, which leads to loss of the analgesic effect after small-fiber neuropathy, remains unclear. (More)
BACKGROUND Bilateral and isolated abducens nerve palsy is a rare initial presentation after aneurysms rupture. Several possible mechanisms including intracranial hypertension have been purposed. To date, there have been no reports with objective measurements to demonstrate the relationship between intracranial pressure and isolated abducens palsy in the(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)
