The bones of the popliteal fossa are the femur and the tibia. Like other flexion surfaces of large joints ( groin , armpit , cubital fossa and essentially the anterior part of the neck ), it is an area where blood vessels and nerves pass relatively superficially, and with an increased number of lymph nodes .
The common fibular nerve is the smaller terminal branch of the sciatic nerve. The common fibular nerve has root values of L4, L5, S1, and S2. It arises from the superior angle of the popliteal fossa and extends to the lateral angle of the popliteal fossa, along the medial border of the biceps femoris.
Smaller arteries carry blood supply from the popliteal artery to the calf and into the foot. [4] Blockages caused by plaque build-up or atherosclerosis in any of these arteries can reduce leg blood circulation, causing leg pain that may interfere with daily life. [4] Standard popliteal bypass surgery involves the bypass of the popliteal artery. [5]
The depression at the back of the knee, or kneepit is the popliteal fossa, colloquially called the ham. The tendons of the above muscles can be felt as prominent cords on both sides of the fossa—the biceps femoris tendon on the lateral side and the semimembranosus and semitendinosus tendons on the medial side.
The popliteal artery entrapment syndrome (PAES) is an uncommon pathology that occurs when the popliteal artery is compressed by the surrounding popliteal fossa myofascial structures. [1] This results in claudication and chronic leg ischemia. This condition mainly occurs more in young athletes than in the elderlies. [2]
The nerve then runs straight down the back of the leg, through the popliteal fossa to supply the ankle flexors on the back of the lower leg and then continues down to supply all the muscles in the sole of the foot. [50] The pudendal (S2-S4) and coccygeal nerves (S5-Co2 [check spelling]) supply the muscles of the pelvic floor and the surrounding ...
The sciatic nerve can be blocked at different locations. At the popliteal fossa, the sciatic nerve divides into its two branches: The tibial and the common peroneal nerve. If surgery is performed on the ankle, achilles tendon or foot a popliteal block can be performed, affecting the two branches of the sciatic nerve. It is done above the knee ...
Its branches are all cutaneous, and are distributed to the gluteal region, the perineum, and the back of the thigh and leg. The inferior clunial nerves (or gluteal branches), three or four in number, turn upward around the lower border of the gluteus maximus, and supply the skin covering the lower and lateral part of that muscle.
