What is circumflex femoral?
The medial circumflex femoral artery (internal circumflex artery, medial femoral circumflex artery) is an artery in the upper thigh that helps supply blood to the neck of the femur. Damage to the artery following a femoral neck fracture may lead to avascular necrosis (ischemic) of the femoral neck/head.
What muscles does the lateral circumflex femoral artery supply?
The main function of the lateral circumflex femoral artery is to supply blood to the hip joint, knee joint, parts of the femur, quadriceps femoris, tensor fasciae latae, as well as skin of the anterolateral aspect of the thigh.
Where does the lateral circumflex femoral artery come from?
The lateral circumflex femoral artery originates from the profunda femoral artery or femoral artery directly. After giving off a large branch to the rectus femoris muscle, it splits into transverse and descending branches.
What is profunda femoris?
The profunda femoris artery provides the main blood supply to the thigh. It usually arises from the posterolateral aspect of the femoral artery and descends first laterally, and then posterior to the superficial femoral artery.
What is Retinacular artery?
branches of the medial and lateral circumflex femoral arteries that extend to the head of the femur within the retinacular folds of synovial membrane surrounding the neck of the femur. Collectively, these arteries provide the main blood supply to the femoral head.
Which of the following arteries give rise to the lateral femoral circumflex artery?
Deep femoral artery (arteria profunda femoris) The lateral femoral circumflex artery (LFCA) is the largest branch of the deep femoral artery, arising from the lateral aspect. In 67% of cases it arises 1.5 cm distal to the origin of the CFA, while in 14–20% it arises directly from the CFA.
Which artery supplies the rectus femoris?
Blood is supplied to the Rectus Femoris via descending branch of the lateral circumflex femoral (LCF) artery.
Where is profunda femoris?
The deep femoral artery (profunda femoris artery) is the largest branch of the femoral artery, located deep within the thigh….Deep femoral artery.
| Origin | Femoral artery |
|---|---|
| Supply | Extensors of the thigh, flexors of the thigh, adductors of the thigh, skin of the medial thigh region, proximal aspect of femur |
What is a profunda?
Definition of profunda : any of various deep-seated arteries or veins: such as. a : the largest branch of the brachial artery in the upper part of the arm. b : the deep femoral artery.
What artery supplies the femoral head?
The majority of the blood supply to the head of the femur comes from the medial and lateral circumflex branches of the profunda femoris, which itself is a branch of the femoral artery (the profunda femoris is the deep penetrating branch of the upper thigh).
What artery goes to femoral head?
The femoral head receives its blood supply primarily from the medial femoral circumflex artery (MFCA). Of all of the branches of this artery, the deep branch is the most important.
What is the origin of the lateral circumflex femoral artery?
The lateral circumflex femoral artery originates from the profunda femoral artery or femoral artery directly. After giving off a large branch to the rectus femoris muscle, it splits into transverse and descending branches. Occasionally an oblique branch presents between the transverse and descending branches (Fig. 78.3 ).
What does the rectus femoris do?
The rectus femoris is part of a group of muscles in the thigh that helps you flex your hip, extend the knee, and lift the thigh. But, what happens when it gets injured?
What is the extracapsular ring of the femur?
The extracapsular arterial ring consists of the lateral femoral circumflex artery and the medial femoral circumflex artery, which arise from the profunda femoris. The medial femoral circumflex artery and its branches supply most of the blood to the head and neck of the femur.
How do you harvest the rectus femoris?
The rectus femoris muscle or a portion of it can be harvested based on the branch from the descending branch of the LCFA. (Top) The external rotators of the hip are present along the posterior surface of the acetabulum. Note also the origin of the semimembranosus from the lateral portion of the ischial tuberosity.
