研究室紹介
Professor Jae Chul Sim's research lab specializes in interventional pain management and image-guided spinal interventions, with a focus on improving the accuracy and efficacy of epidural and nerve block procedures. The lab investigates fluoroscopic and ultrasound-guided techniques for targeted delivery of therapeutic agents, including transforaminal epidural injections, radiofrequency denervation, and genicular nerve blocks. Key research directions include optimizing catheter placement, evaluating contrast flow dynamics, and minimizing complications such as intravascular needle placement or misplacement of catheters in the epidural space.

15In patients with chronic discogenic low back pain, percutaneous RF denervation of the ramus communicans nerve should be considered as a treatment option.
BACKGROUND: Based on the necessity to confirm the epiradicular catheter misplacement, epiradicular threshold current for the confirmation of catheter tip localization is required. METHODS: Thirty-four adult patients with low extremity radiating pain were to receive epiradicular catheterization at the lumbosacral level. The epidural space was accessed percutaneously in cranial to caudal direction. A metal coil-reinforced epidural catheter was inserted and advanced caudolaterally toward the target

BACKGROUND: Retrograde interlaminar ventral epidural injection (RIVEI) may hypothetically be more effective if the catheter is placed at the ventrocaudal aspect of the exiting nerve. We tested that hypothesis by measuring ventral and dorsal epidural contrast flow during RIVEI. METHODS: To perform RIVEI, a 17 G Tuohy needle was inserted to access the epidural space. A 19 G epidural catheter was inserted and advanced through the needle, passing in a caudal direction to the lower aspect of the cont
Background: In most cases of lumbosacral radiculopathy secondary to stenosis, the site of impingement usually lies at the level of the supra-adjacent intervertebral disc, which is rostral to the conventional bevel position of the lumbar transforaminal epidural injection needle. However, one cannot always guarantee a rostral spread of injectate to bathe the epidural/preganglionic portion of the nerve root. The contrast flow patterns and intravascular needle placement of fluoroscopically guided lu
Background: The genicular arteries (GAs) can be utilized for genicular nerve block. We aimed to evaluate the ability to localize GAs under ultrasound in patients with chronic knee pain.
Background: The aim of the study is to evaluate the relevant spreading for contrasts in the ventral and dorsal epidural space during retrograde interlaminar ventral epidural injections (RIVEIs)with the catheter tip placed ventral or dorsal to the spinal nerve. Methods: For RIVEIs, a 17G Tuohy needle...

Background: Although the paramedian approach for epidural blockade is useful in some clinical situation, the parameters which are correlated with the distance from skin to the epidural space has not been established. Methods: We studied in 143 patients having elective continuous epidural blocks for relief of postoperative pain. All blocks were performed using paramedian approach with Tuohy needle in the lumbar (group 1, n=100) and thoracic (group 2, n=45) area. We measured the distance from skin
Purpose : The Swedish Interactive Thresholding Algorithm (SITA) strategies is a new diagnostic tool of Humphrey automatic perimetry and has been reported to reduce testing time without loss of useful diagnostic information. To test the usefulness of this new diagnostic method, we compared the SITA and full threshold diagnostic method, which had been used previously. Methods: Forty six patients (46 eyes) who were followed up for glucoma or ocular hypertension were in this study. Autoperimetry was
Fibromyalgia is a chronic syndrome, which is characterized by widespread pain, unrefreshed sleep, a disturbed mood and fatigue. Until more is understood about fibromyalgia and myofascial pain syndrome, the management issues concerning its treatment remain difficult and problematic. Symptom management, with emphasis on functional restoration, takes priority. Such treatment should ideally be offered as part of a multidisciplinary treatment program using both pharmacological and nonpharmacological
