该 腘窝 is a jewel formed despondency found back to the knee joint. Essential nerves and vessels go from the thigh to the leg by crossing through this fossa and the muscles of the thigh and the leg shape its limits. This article will talk about the anatomical structure and the substance of the popliteal fossa, trailed by any important clinical pathology.
These outskirts are shaped by the muscles in the back compartment of the leg and thigh:
- Superomedial outskirt – semimembranosus.
- Superolateral outskirt – 股二头肌.
- Inferomedial outskirt – average leader of the gastrocnemius.
- Inferolateral outskirt – parallel leader of the gastrocnemius and plantaris.
The popliteal fossa additionally has a story and a rooftop. The floor of the popliteal fossa is shaped by the back surface of the knee joint container, and by the back surface of the femur. The rooftop is made of up two layers; popliteal belt and skin. The popliteal belt is consistent with the sash lata of the leg.
The popliteal fossa is the principal channel for neurovascular structures entering and leaving the leg. Its substance is (average to parallel):
- Popliteal conduit
- Popliteal vein
- Tibial nerve
- Regular fibular nerve
The tibial and regular fibular nerves are the shallowest of the substance of the popliteal fossa. They are both branches of the sciatic nerve. The normal fibular nerve takes after the biceps femoris ligament, running along the sidelong edge of the popliteal fossa. The little saphenous vein punctures the popliteal belt of the popliteal fossa to enter the precious stone and discharge into the popliteal vein. In the popliteal fossa, the most profound structure is the popliteal course. It is a continuation of the femoral course and goes into the leg to supply it with blood.
Popliteal Fossa Pain
Knee torment is more typical in the front, 平均, and horizontal part of the knee than in the back part of the knee. The distinctive judgments for back knee torment incorporate pathology to the bones, musculotendinous structures, 筋, as well as to the bursas. Less normal are neurologic and vascular wounds. Additionally tumors, 例如, a start tumor that contains both bone and ligament and normally happens close to the finish of a long bone (osteochondroma) or hard tumors. The Delicacy of palpation over the ligaments or muscles in the back of the knee can show muscle or ligament damage. Discomfort or swelling in the popliteal territory proposes a radiation or growth.
An exact comprehension of knee life structures, the physical examination and of the differential analysis is expected to precisely assess and treat back knee pain.
