Medial Femoral Circumflex
The medial circumflex femoral artery (internal circumflex artery, medial femoral circumflex artery) is an artery in the upper thigh that arises from the profunda femoris artery''.'' Damage to the artery following a femoral neck fracture may lead to avascular necrosis (ischemic) of the femoral neck/head. Structure Origin The medial femoral circumflex artery arises from the posterior medial aspect of the profunda femoris artery''.'' The medial femoral circumflex artery may occasionally arise directly from the femoral artery. Course and relations It winds around the medial side of the femur, passing first between the pectineus and iliopsoas muscles, and then between the obturator externus and the adductor brevis muscles. Branches At the upper border of the adductor brevis it gives off two branches: * The '' ascending branch'' * The ''descending branch'' descends beneath the adductor brevis, to supply it and the adductor magnus; the continuation of the vessel passes backwar ...

Deep Femoral Artery
The deep artery of the thigh, (profunda femoris artery or deep femoral artery) is a large branch of the femoral artery. It travels more deeply (posteriorly) than the rest of the femoral artery. Structure The deep artery of the thigh branches off the posterolateral side of the femoral artery soon after its origin. It travels down the thigh closer to the femur than the femoral artery. It runs between the pectineus muscle and the adductor longus muscle. It runs on the posterior side of adductor longus muscle. It pierces the adductor magnus muscle, and may be known as the fourth perforating artery as it continues. The deep femoral artery does not leave the thigh. Branches The deep artery of the thigh gives off the following branches: * Lateral circumflex femoral artery. * Medial circumflex femoral artery. * 3 Perforating arteries - perforate the adductor magnus muscle to the posterior and medial compartments of the thigh to connect with the branches of the popliteal artery behind t ...

Adductor Magnus
Adductor may refer to: * One of the anatomical terms of motion * Adductor muscle (other) * Adductor canal 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. Structure The adductor canal extends ... {{disambiguation ...

Hip Dislocation
A hip dislocation is when the thighbone (femur) separates from the hip bone (pelvis). Specifically it is when the ball–shaped head of the femur (femoral head) separates from its cup–shaped socket in the hip bone, known as the acetabulum. The joint of the femur and pelvis (hip joint) is very stable, secured by both bony and soft-tissue constraints. With that, dislocation would require significant force which typically results from Major trauma, significant trauma such as from a motor vehicle collision or from a Falling (accident), fall from elevation. Hip dislocations can also occur following a hip replacement or from a developmental abnormality known as hip dysplasia. Hip dislocations are classified by fracture association and by the positioning of the dislocated femoral head. A posteriorly positioned head is the most common dislocation type. Hip dislocations are a medical emergency, requiring prompt placement of the femoral head back into the acetabulum (Reduction (orthoped ...

Femoral Neck
The femoral neck (femur neck or neck of the femur) is a flattened pyramidal process of bone, connecting the femoral head with the femoral shaft, and forming with the latter a wide angle opening medialward. Structure The neck is flattened from before backward, contracted in the middle, and broader laterally than medially. The vertical diameter of the lateral half is increased by the obliquity of the lower edge, which slopes downward to join the body at the level of the lesser trochanter, so that it measures one-third more than the antero-posterior diameter. The medial half is smaller and of a more circular shape. The anterior surface of the neck is perforated by numerous vascular foramina. Along the upper part of the line of junction of the anterior surface with the head is a shallow groove, best marked in elderly subjects; this groove lodges the orbicular fibers of the capsule of the hip joint. The posterior surface is smooth, and is broader and more concave than the ante ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
