Is adductor canal block a femoral nerve block?
Background and objectives: Femoral nerve block (FNB), a commonly used postoperative pain treatment after total knee arthroplasty (TKA), reduces quadriceps muscle strength essential for mobilization. In contrast, adductor canal block (ACB) is predominately a sensory nerve block.
What is adductor canal catheter?
Background: Adductor canal (AC) catheters are being used to provide continuous postoperative analgesia after total knee arthroplasty (TKA) surgery. There are anatomical arguments that most AC catheters are being inserted into the femoral triangle (FT) compartment of the thigh rather than the AC compartment.
What does adductor block cover?
The adductor canal block provides anesthesia to the anteromedial knee and the medial aspect of the lower leg, ankle, and foot. This is a sensory block and preserves motor function of the lower extremity.
What does femoral block cover?
Femoral nerve block results in anesthesia of the anterior and medial thigh down to and including the knee, as well as a variable strip of skin on the medial leg and foot. It also innervates the hip, knee, and ankle joints (Figure 3).
What is the femoral canal?
The femoral canal is a potential space that contains fat and lymph nodes and lies medial to the femoral vein just distal to the inguinal ligament. Femoral hernias are relatively infrequent in male patients and are commoner in middle-aged female patients.
How long does adductor block last?
The numbness lasts an average of 16 hours. Studies from HSS show that the pain-relieving properties of a femoral nerve block last much longer – up to 3 days.
How long does femoral block last?
Often we will provide the surgical anesthesia with a spinal/epidural and provide pain relief after surgery with a femoral nerve block. The numbness lasts an average of 16 hours. Studies from HSS show that the pain-relieving properties of a femoral nerve block last much longer – up to 3 days.
What artery begins at the adductor canal?
The femoral artery with its vein and the saphenous nerve enter this canal through the superior foramen.
Is femoral canal same as adductor canal?
The femoral artery. (Canal not labeled, but region visible at center right.) The adductor canal, also known as the subsartorial canal or Hunter’s canal, is an aponeurotic tunnel in the middle third of the thigh. It extends from the apex of the femoral triangle to the adductor hiatus.
