Summary
About 10-30% of all patients with hip fracture have only insufficient analgesic effect of a
femoral nerve block. One of the possible causes of this failure to provide analgesia from a
single nerve block could be the that other nerves occasionally are involved in transmitting
the pain signal. One of the nerves that is believed to give off branches to the hip is the
obturator nerve.
With ultrasound it is possible to make a selective proximal nerve block of the obturator
nerve.
The aim of this trail is to give patients with hip fracture and only insufficient effect of a
femoral nerve block a supplementary obturator nerve block in a randomized manner with either
local anesthetics or placebo in order to access the preoperative analgesic effect.
