The femoral head presents with a depression called the fovea of the head of the femur. Fig 4 – Spiral fracture of the femoral shaft. Fractures of the femoral shaft are typically a high energy injury but can occur in the elderly as a result of a low energy fall. The inferior border of the neck begins lateral to the femoral head and extends to the inferior trochanter. (Cerezal)" This orientation is said to be favorable for the tensed fibers of the ligamentum teres. To access the TeachMeAnatomy 3D Model, you must be a premium subscriber. Femur, upper bone of the leg or hind leg. The neck’s posterior surface has a concave appearance. The head of the femur (thighbone) forms the ball, and the acetabulum forms the socket. It ranges from a well-formed structure in some patients to … The surgical anatomy of the blood supply to the femoral head: description of the anastomosis between the medial femoral circumflex and inferior gluteal arteries at the hip. The distal end of the femur is characterised by the presence of the medial and lateral condyles, which articulate with the tibia and patella to form the knee joint. (Cerezal)". Clinical Relevance: Proximal Femur Fractures, Clinical Relevance: Fractures of the Femoral Shaft. The find out more about our cookies, click here. - Femoral Neck Angle: - neck extends inferolaterally from head to meet shaft of femur at angle of about 125 deg; - angle varies w/ age, stature, & width of pelvis, being less in … Found an error?

The flat popliteal surface lies between them. The principal vessels ascend in the synovial retinaculum, which is a reflection of the lig-amentous capsule onto the neck of the femur. The medial supracondylar line ends at the adductor tubercle, where the adductor magnus attaches. Fig 3 – Posterior surface of the right femoral shaft. It is the site of attachment for the iliofemoral ligament (the strongest ligament of the hip joint). The upper extremity is composed of the head, neck, greater trochanter and lesser trochanter. The head is globular and forms rather more than a hemisphere, is directed upward, medialward, and a little forward, the greater part of its convexity being above and in front. It is the site of attachment for iliopsoas (forceful contraction of which can cause an avulsion fracture of the lesser trochanter). The femur is found in the thigh. 300-302. The femoral head (femur head or head of the femur) is the highest part of the thigh bone (femur). There are also two bony ridges connecting the two trochanters; the intertrochanteric line anteriorly and the trochanteric crest posteriorly. The fovea capitis is a small, concave, depression within the head of the femur that serves as an attachment point for the ligamentum teres (Saladin). Print. The anterior surface of the neck is rough in comparison to the smooth femoral head. The femur is the only bone in the thigh and the longest bone in the body. for more anatomy content please follow us and visit our website: www.anatomynote.com. The hip is a ball-and-socket joint. Femoral Angle of Torsion: Formed by looking at the relationship between the axis of the femoral head and neck and the femoral condyles. It is slightly ovoid in shape and is oriented "superior-to-posteroinferior. It consists of a head and neck, and two bony processes - the greater and lesser trochanters. The head of the femur is a roughly spherical structure that sits superomedially and projects anteriorly from the neck of the femur. https://en.wikipedia.org/w/index.php?title=Femoral_head&oldid=956157721, Wikipedia articles incorporating text from the 20th edition of Gray's Anatomy (1918), Creative Commons Attribution-ShareAlike License, This page was last edited on 11 May 2020, at 20:09. The head of the femur articulates with the acetabulum of the pelvis to create the hip joint. The development of ANFH is associated with steroid use, alcohol use, smoking, auto-immune disorders, … The vastus lateralis originates from this site. The ball-and-socket configuration provides stability while allowing a wide range of joint motion. This information is intended for medical education, and does not create any doctor-patient relationship, and should not be used as a substitute for professional diagnosis and treatment. The medial and lateral collateral ligaments of the knee originate from their respective epicondyles. The upper third of the artery is contained in the femoral triangle, which is also know… It is mandatory to procure user consent prior to running these cookies on your website. At the juncture, where the middle and the lower third of the thigh meet, this artery ends, and here it passes through an opening in the Adductor magnus, and becomes the popliteal artery. In younger patients they tend to occur as a result of high energy accidents. The socket is formed by the acetabulum, which is part of the large pelvis bone. Arterial blood supply to the femoral head is achieved through an anastomosis of three sets of arteries (Figure 6.13). Anatomy and pathology of avascular necrosis (AVN) of the femoral head. Normally the femoral head-neck junction is waist-shaped, with the femoral neck narrower than its head. This place is known as the femoral head. Treatment may be nonoperative or operative depending on the location of the fracture and degree of fracture displacement. The smooth convexity of the femoral head is disrupted on the posteroinferior surface by a depression known as the fovea for the ligament of the head … Necessary cookies are absolutely essential for the website to function properly. Try again to score 100%. They can often occur as a spiral fracture, which causes leg shortening. It is believed that the blood supply to the femoral head decreases causing the bone to deteriorate and actually die. Normal femur has an angle of torsion between 12 and 15 degrees. New York, NY: McGraw-Hill, 2007. The fovea capitis is located "slightly posterior and inferior to the center of the articular surface of the femoral head (Cerezal)" Furthermore, unlike the head of the femur, the fovea capitis lacks any hyaline cartilage. It is supported by the femoral neck. The socket has a rim o… While the cartilage covers the entire head of the femur, the acetabulum cartilage is in the shape of a horseshoe with a depression (fossa) in the center of the socket. It is composed of the upper extremity, body and lower extremity and provides several muscular origins and insertions. An increase in this angle is termed anteversion, while a decrease in this angle is termed retroversion*. Ruler in centimeters at left side. From here, it passes midway between the anterior spine of the ilium and symphysis pubis and continues down the medial and front side of the thigh. Incidence of appearance depends on the method of visualization used by different authors; it is observed in 11 % of cases by angiographic CT examination [] compared to 100 % of cases in a classical anatomical study with colored silicone injection [6, 11–13, 15]. They are more prevalent in women. Applied Anatomy. At this time, the ball (femoral head) of the hip joint begins to degenerate. The hip is a ball-and-socket joint. Neurovascular structures at risk include the femoral nerve and artery. Is our article missing some key information? Similar conditions occur in humans. RadioGraphica. Anatomy . The ball (femoral head) is the rounded top of the femur, commonly known as the thighbone. Nov. 2015. It acts as the site of origin and attachment of many muscles and ligaments, and can be divided into three parts; proximal, shaft and distal. RSNA, Oct. 2010. Proximally, the medial border of the linea aspera becomes the pectineal line. The coxofemoral joint is a diarthrodial articulation between the femoral head and acetabulum. It acts as the site of origin and attachment of many muscles and ligaments, and can be divided into three parts; proximal, shaft and distal.. As the method of injury is typically high energy, the surrounding soft tissues may also be damaged. Make the changes yourself here! The ligament passes from the transverse ligament and acetabular notch of the acetabulum to the femoral head where it inserts into a shallow depression called the fovea capitis. The head-neck junction morphology can be quantified by the anterior offset or the alpha angle. A slippery tissue called articular cartilage covers the surface of the ball and the socket. In this article, we shall look at the anatomy of the femur - its attachments, bony landmarks, and clinical correlations. [caption id="attachment_5514" align="aligncenter" width="526"], [caption id="attachment_5515" align="aligncenter" width="533"], [caption id="attachment_5517" align="aligncenter" width="344"], [caption id="attachment_39849" align="aligncenter" width="885"], [caption id="attachment_5519" align="aligncenter" width="571"], [caption id="attachment_5520" align="aligncenter" width="575"]. The hip is the largest “ball-and-socket” joint in the body. Gross anatomy. The loss of leg length is due the bony fragments overriding, pulled by their attached muscles. Cerezal, Luis. The proximal femoral head articulates with the acetabulum of the pelvis, forming a “ball-and-socket” joint. We are pleased to provide you with the picture named Blood Supply Of The Femoral Head.We hope this picture Blood Supply Of The Femoral Head can help you study and research. (There are four types of bone: long bones, short bones, flat bones, and irregular bones.) The femoral head's surface is smooth. The socket (acetabulum) is located in the pelvis. By visiting this site you agree to the foregoing terms and conditions. The condyles are the points of articulation (connection) with the tibia, which is a lower leg bone. This splits distally to form the medial and lateral supracondylar lines. Our 3D anatomical model provides you with hands-on, interactive and valuable learning tool right here on your device. It consists of a head and neck, and two bony processes – the greater and lesser trochanters. The ball is called the “femoral [fem-er-uhl] head,” which is the top of the femur or thigh bone. The proximal aspect of the femur articulates with the acetabulum of the pelvis to form the hip joint. This artery begins immediately behind the inguinal ligament. Femoral vein (Vena femoralis) The femoral vein is a large vessel located deep within the thigh.It is sometimes referred to as the superficial femoral vein in order to distinguish it from the deep femoral vein.This term is, however, misleading and rarely used due to the fact that the vessel is located deep in the thigh. These fractures can be broadly classified into two main groups: The shaft of the femur descends in a slight medial direction. Fig 1 – The anterior surface of the proximal right femur.
