Fascia iliaca compartment block is more effective than the 3-in-1 block in producing simultaneous blockade of the LFC and femoral nerves in adults.

Both techniques provide sensory blockade of the three lumbar plexus nerves that supply the thigh in only 35% of procedures.

Although sensory blockade of the femoral nerve is provided by both block procedures equally, that of the LFC is obtained both more rapidly and consistently with the fascia iliaca compartment block.

The spread of LA to the three principal nerves is difficult to obtain and unpredictable even though the LA can travel sufficiently under the fascia situated between the psoas and iliacus muscles to block the femoral and LFC nerves, it does not always migrate proximally in sufficient quantities to block the obturator nerve. The genitofemoral and obturator nerves lie on the internal edge of the psoas muscle, in a different muscle plane than the femoral and LFC nerves.
