Lumbar puncture in the lateral decubitus position will make the neonates uncomfortable and is likely to cause position change and unstable vital signs, and the application of sedative drugs will cause adverse effects. This study explored a novel method for lumbar puncture in the prone position for ...
The puncture site (between L2 and L3) is aseptically prepared and infiltrated with 2 to 3 ml of local anesthetic. A 25-cm, 16-gauge needle with a marker on the needle shaft is inserted through the desensitized skin and advanced until its tip contacts the transverse process of L2 or L3....
7.2.1 Lumbar Puncture As the spinal cord ends at approximately the level of the second lumbar vertebra, but the subarachnoid space continues to the level of the second sacral vertebra, samples of cerebrospinal fluid can be extracted. Prior to the extraction of the cerebrospinal fluid, pressure me...
Group A: The patient was placed in the prone position and the responsible segment was localised by fluoroscopy. According to the pre-determined surgical approach, puncture was performed under fluoroscopic guidance. After confirming the good position, the guide wire was placed. The guide rods were ...

c Intraoperative positioning of the long needle puncture. d Placement of disposable working tube. e the light source was placed and the soft tissues around the facet joint were eliminated. f Surgical view in the working tube. g On the symptomatic side, the same method was used as on the ...
The termination of the spinal cord, termed the conus medullaris, occurs at the L1-L2 vertebrae. This structure is clinically significant for procedures in this area, most notably the lumbar puncture. A lumbar puncture (spinal tap) is performed by inserting a needle between the vertebral lamina ...
if required. An imaginary line drawn to the annular puncture site through the foramen designated the entry point into the skin and surgical trajectory. Prior to surgery, we used axial MRI and CT images to calculate the distance of the skin entry point of the needle from the midline and the...
A spinal puncture needle (20G puncture needle) is accurately inserted into the skin, and the angle and position are determined by the transducer and anatomy. Our target is the back of the intervertebral foramen and the needle is inserted along the lateral edge of the lamina, where the ...
internum and nerve roots of the cauda equina. Because of the large size of the subarachnoid space and relativeabsenceof neural structures, this space is most suitable for the withdrawal of CSF bylumbar puncture(LP). The LP is usually preformed between the third andfourth lumbar vertebra(L3 to...
