A femoral nerve block is a

analgesia in the leg. The block works by affecting the femoral nerve
.

A femoral nerve block (FNB) results in anesthesia of the skin and muscles of the

knee joint, as well as the skin on the medial aspect of the leg below the knee joint.[1]

The block can be performed using

nerve stimulator.[2]

For hip surgery, a femoral nerve block and

visual analog scale at 24 hrs and the incidence of nausea, vomiting and oversedation.[3]

For knee surgery, a femoral nerve block may lead to delayed postoperative mobilization of the patient and greater risk of falls as it causes motor blockade of the quadriceps muscles.[4] Due to the sparing of the thigh muscles the adductor canal block is becoming a preferred choice for providing post-operative analgesia for knee surgery.[5]
