If you do not agree to the foregoing terms and conditions, you should not enter this site. New York, NY: McGraw-Hill, 2007. The medial and lateral collateral ligaments of the knee originate from their respective epicondyles. 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. Is our article missing some key information? It is coated with cartilage in the fresh state, except over an ovoid depression, the fovea capitis, which is situated a little below and behind the center of the femoral head, and gives attachment to the ligament of head of femur. Applied Anatomy. 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.. Print. Clinical Relevance: Proximal Femur Fractures, Clinical Relevance: Fractures of the Femoral Shaft. But opting out of some of these cookies may affect your browsing experience. The femoral head's surface is smooth. The vastus lateralis originates from this site. This artery begins immediately behind the inguinal ligament. RSNA, Oct. 2010. Femoral access is still the most common mode of vascular access for coronary angiography and intervention in the United States, though transradial access is on the rise. 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. It is the site of attachment for many of the muscles in the gluteal region, such as gluteus medius, gluteus minimus and piriformis. Capsular and Pericapsular Contributions to Acetabular and Femoral Head Perfusion. 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. Gross anatomy. At this time, the ball (femoral head) of the hip joint begins to degenerate. It also serves as the anterior attachment of the hip joint capsule. Make the changes yourself here! "Anatomy, Biomechanics, Imaging, and Management of Ligamentum Teres Injuries." The ball (femoral head) is the rounded top of the femur, commonly known as the thighbone. On the posterior surface of the femoral shaft, there are roughened ridges of bone, called the linea aspera (Latin for rough line). 6th ed. The loss of leg length is due the bony fragments overriding, pulled by their attached muscles. The fovea capitis is said to contain vascular canals in two-thirds of individuals, but "their contribution to femoral head vascularity varies. A slippery tissue called articular cartilage covers the surface of the ball and the socket.

Fig 6 – Posterior surface of the distal right femur. Distally, the linea aspera widens and forms the floor of the popliteal fossa, the medial and lateral borders form the medial and lateral supracondylar lines. Fig 1 – The anterior surface of the proximal right femur. Our aim was to perform three-dimensional CT analysis of femoral head and bump anatomy to quantify common hip pathologies (FAI and hip dysplasia) vs controls. Original Author(s): Oliver Jones Last updated: November 13, 2020 Fig 2 – The posterior surface of the right femur. The proximal femoral head articulates with the acetabulum of the pelvis, forming a “ball-and-socket” joint. The head of the femur is a ball like bone structure that attaches to the rest of the femur by a section of bone called the femoral neck and sits inside the acetabular fossa.The greater trochanter is located at the top, outside edge of the femur and you can feel it when you push against the side of your hip. Gross pathology specimen of the head of the femur with some synovium attached at the bottom and the ligament attached at the top. The anterior surface of the neck is rough in comparison to the smooth femoral head. The femoral head presents with a depression called the fovea of the head of the femur. This manifests clinically as a shortened and externally rotated lower limb. We also use third-party cookies that help us analyze and understand how you use this website. The neck’s posterior surface has a concave appearance. It consists of a head and neck, and two bony processes - the greater and lesser trochanters. The femoral head is removed in total hip replacement surgery. This brings the knees closer to the body’s centre of gravity, increasing stability. Fig 5 – Anterior surface of the distal right femur. 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. Ruler in centimeters at left side. Fig 4 – Spiral fracture of the femoral shaft. 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. The flat popliteal surface lies between them. By visiting this site you agree to the foregoing terms and conditions. The ball is called the “femoral [fem-er-uhl] head,” which is the top of the femur or thigh bone. There are also two bony ridges connecting the two trochanters; the intertrochanteric line anteriorly and the trochanteric crest posteriorly. Necessary cookies are absolutely essential for the website to function properly. The end result is a malformed hip joint and secondary arthritis. The hip joint in the pelvic region consists of two components: a deep cavity called the acetabulum, which is part of the pelvis, and a spherical ball called the femoral head encompassed by the acetabular fossa. This formation allows for three planes movement at the hip joint: abduction and adduction in the frontal plane, flexion, and extension in the sagittal plane and internal and external rotation in the horizontal plane.Distally, the femoral condyles of the femur articulate with the condyles of the tibia, making the tibiofemoral joint. (There are four types of bone: long bones, short bones, flat bones, and irregular bones.) They can often occur as a spiral fracture, which causes leg shortening.

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]. Anatomy and pathology of avascular necrosis (AVN) of the femoral head. The hip is the largest “ball-and-socket” joint in the body. The ball-and-socket configuration provides stability while allowing a wide range of joint motion. It is composed of the upper extremity, body and lower extremity and provides several muscular origins and insertions. This splits distally to form the medial and lateral supracondylar lines. 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). A closed femoral shaft fracture may result in considerable haemorrhage (1000-1500ml).
