Fascia iliaca block

A nerve block

This anaesthetic involves blocking the nerves that supply the area where the surgeon will be operating. This reduces the number of anaesthetic drugs we need to give which in turn reduces the side effects - feeling sick for example.

A fascia iliaca block can be used to numb some of the nerves that supply the hip and the knee e.g. when a patient has broken their hip. The block is often performed when you are asleep and involves locating the appropriate nerves in the groin. This is sometimes performed with the anaesthetist using an ultrasound machine. Local anaesthetic is then injected around the nerves. This may cause some temporary numbness and weakness in your leg.

The risks of having a fascia iliaca block are minimal, but include:

  • Some localised bruising
  • Failure to provide adequate pain relief
