[Comment] Atraumatic lumbar puncture needles: practice needs to change

Lumbar puncture is a procedure used to obtain cerebrospinal fluid for diagnostic or therapeutic purposes and spinal anaesthesia. A retrospective study1 showed that in 2014, lumbar puncture was done in 1·4% of patients admitted to hospital and 0·8% of patients who were admitted to Accident and Emergency departments in France. Extrapolating these figures to the National Health Service Accident and Emergency attendance data indicates that more than 160 000 lumbar punctures are done in the UK annually.
