The history of the design of spinal needle tips is discussed, from the first needles used by J. Leonard Corning in 1885 to innovative, modern needle designs that continue to appear on the market. The shape of the needle tip started as a cutting bevel and developed into the atraumatic tip and the pencil-point tip in current common use. Innovative designs such as the stylet-tipped needle and the ...

BACKGROUND Percutaneous kyphoplasty using a bone expander polymer device, such as percutaneous vertebroplasty and balloon kyphoplasty, is a therapeutic intervention for painful osteoporotic vertebral body compression fractures. Typically the procedure involves placement of bilateral Sky Bone Expanders in the fractured vertebral body via a transpedicular approach. We describe performance of "SKy...

CASE REPORT Two cases are presented in which the complication of dural puncture is documented in the context of a lumbar transforaminal epidural steroid injection. The hazard of dural puncture during transforaminal epidural injections, the anatomy of the dural and thecal sac, the potential for subdural injections, and relevant literature are reviewed. DESIGN Report of two cases. BACKGROUND ...

BACKGROUND Continuous femoral nerve block (CFNB) improves postoperative analgesia after total knee arthroplasty (TKA). The aim of this study was to investigate the clinical efficacy and complications of our in-plane three-step needle insertion technique that was devised to reduce the risk of direct femoral nerve injury during CFNB in anesthetized patients. METHODS This retrospective study inc...

INTRODUCTION Percutaneous renal surgery has been considered one of the most important advances in urology. There are several possibilities to perform a kidney puncture such as using fluoroscopy, ultrasound or both. The aim of this article is to describe our puncture technique. MATERIAL AND METHODS Correct puncture is one of the most critical and challenging steps during percutaneous surgery. ...

REGIONAL anesthesia has evolved in recent years from a technique into an art, practiced by some pioneering anesthesiologists. As with any art form, regional anesthesia has obtained a level of complexity not seen before. Until recently, regional anesthesia was used by a select group, using sophisticated wording and techniques that prohibited its widespread implementation. However, with the devel...

PURPOSE We aimed to evaluate the accuracy of a needle-placement robot for biopsy and radiofrequency ablation on an abdominal phantom. METHODS A master-slave robotic system has been developed that includes a needle-path planning system and a needle-inserting robot arm with computed tomography (CT) and CT fluoroscopy guidance. For evaluation of its accuracy in needle placement, a commercially a...

INTRODUCTION We aimed to compare the accuracy between the standard anterior technique of shoulder injection and the new superomedial technique modified from Neviaser arthroscopic portal placement. Intra-articular placement, especially at the long head of biceps (LHB) tendon, and needle depth were evaluated. METHODS Fifty-eight patients (ages 57 ± 10 years) requiring shoulder arthroscopy in th...

Spinal anesthesia is often the preferred technique of anesthesia for cesarean delivery. It is a simple procedure with rapid onset and deep sensory block effect that produces excellent operating conditions (1). As a complication of spinal anesthesia, post-dural puncture headache (PDPH) is caused by the needle penetration of the dura matter and loss of cerebrospinal fluid (CSF). During the postpa...

conclusions we think one of the influential factors for leading a guidewire and catheter into a nominated vein may be the left sided bevel of the needle at the time of internal jugular vein needle and catheter insertion. we were required to continue going towards the subclavian vein and accidentally turned into the left internal mammary vein. introduction central venous catheter placement is a ...
