Illustration depicting lumbar puncture (spinal tap) Spinal needles used in lumbar puncture Illustration depicting common positions for lumbar puncture procedure. The person is usually placed on their side (left more commonly than right). The patient bends the neck so the chin is close to the chest, hunches the back, and brings knees toward the ...
Types of epidural needles include: [3] The Crawford Needle; The Tuohy Needle; The Hustead Needle; The Weiss Needle; The Sprotte Spezial Needle; Other Epidural Needles : Other less popular types are the Wagner needle (1957), the Cheng needle(1958), the Crawley needle (1968), the Foldes needle (1973), and the Bell needle (1975)—all variants of the Huber design with a blunted tip of varying ...
Post-dural-puncture headache or post-spinal headache [4] – Associated with the size and type of spinal needle used. A 2020 meta analysis recommended use of the 26G atraumatic spinal needle to lower the risk of PDPH – specifically, the Braun Atraucan 26G needle. [10]
It is the space within the thecal sac which extends from below the end of the spinal cord (the conus medularis), typically at the level of the first to second lumbar vertebrae down to tapering of the dura at the level of the second sacral vertebra. The dura is pierced with a needle during a lumbar puncture (spinal tap).

Lumbar puncture is carried out under sterile conditions by inserting a needle into the subarachnoid space, usually between the third and fourth lumbar vertebrae. CSF is extracted through the needle, and tested. [34] About one third of people experience a headache after lumbar puncture, [34] and pain or discomfort at the needle entry site is ...
The French scale measures the outer diameter of the catheter, not the size of the internal drainage channel (inner diameter). For instance, a two-way catheter of 20 Fr and a three-way catheter of 20 Fr have the same outer diameter, but the three-way catheter has an additional channel for irrigation, reducing the size of its drainage channel.
In situations when only small amounts of CSF are to be drained to reduce ICP's (e.g. in idiopathic intracranial hypertension), drainage of CSF via lumbar puncture can be used as a treatment. Non-invasive measurement of intracranial pressure is being studied. [28]
