fem·o·ral nerve

[TA]
arises as a branch of the lumbar plexus, conveying fibers from the second, third, and fourth lumbar nerves through the substance of the psoas muscle and enters the thigh via the retroinguinal muscular space posterior to the inguinal ligament, lateral to the femoral vessels; it arborizes within the femoral triangle into muscle branches to the sartorius, pectineus, and quadriceps muscles and anterior femoral cutaneous branches to the skin of the anterior and medial region of the thigh; its terminal branch is the saphenous nerve by which it supplies the skin of the medial leg and foot.

fem·o·ral nerve

(fem'ŏr-ăl nĕrv) [TA]
Arises from the second, third, and fourth lumbar nerves in the substance of the psoas muscle and enters the thigh through the muscular lacuna beneath the inguinal ligament, lateral to the femoral vessels; it arborizes within the femoral triangle into muscle branches to the sartorius, pectineus, and quadriceps muscles and anterior femoral cutaneous nerves to the skin of the anterior and medial region of the thigh; its terminal branch is the saphenous nerve by which it supplies the skin of the medial leg and foot.
Synonym(s): nervus femoralis [TA] .

femoral nerve

One of the main nerves of the leg. It branches widely to run into the group of large muscles on the front of the thigh and to carry back sensation from the skin on the front and inner aspects.

The slide plan: Thereafter the cropped femoral nerve was cut into 11 pieces (A1-A11) of which first two pieces (A1 and A2) of 5 mm length each and next nine (A3-A11) pieces of 4 mm length each were separated.
In 1887, Crile [1] performed lower limb amputations by exposing the sciatic nerve in the gluteal fold and femoral nerve in the inguinal fold and administering cocaine in the intraneural sheath.
The risk of infection would be substantially increased for elderly patients with continuous femoral nerve block time of over 48 h as the femoral nerve puncture catheter was near the perineum, with potential risk of infection, and the patients were often associated with diabetes preoperatively.20 In addition, TKA patients were often prescribed with low molecular weight heparin and other anticoagulants before and after surgery to prevent the occurrence of deep vein thrombosis, so there is a potential risk of bleeding at the puncture site, and catheterization may increase the risk of local hematoma formation.
After the 20-week observation period, the animals in experiment III were subjected to retrograde labeling to assess precision of reinnervation (Figures 8(a)-8(c)), a factor that can influence the functional outcome after femoral nerve injury and regeneration in rats [23].
We used motor blockade as a surrogate of sensory blockade of the femoral nerve, obturator nerve, and the lumbosacral trunk.
The percutaneous decompression of these hematomas is a high-risk selection but if performed successfully can relieve intractable pain and support functional restoration of the femoral nerve [10].
Both muscles receive innervation from the femoral nerve proximal to the incision area.
Pain was controlled by a femoral nerve sheath catheter block and oral non-steroidal analgesics, positioned by the Stimu Long Plus 19 g nerve locator (Germany).
