cortices. femurs or femora / ˈ f ɛ m ər ə /), or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrate, the largest bone of the human body.The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia and kneecap, forming the knee joint. Femur, also called thighbone, upper bone of the leg or hind leg. plane - between the Onthe lateral view the shaft is aligned with the anterior half ofthe lateral condyle. Parallel to the lateral cortex of femur slopes ~10 degree s, medial cortex slopes ~25 degrees in the axial plane Normally, the knee joint is parallel to the ground. On the anterior surface of the distal femur, toward the anterior apex of the intercondylar fossa is an area known as the patellar surface or trochlear groove. It is a trapezoidal shaped bone that makes up the top of your joint and sits just behind your knee cap. Medial and lateral condyles – Rounded areas at the end of the femur. It consists of two large structures called condyles, which is the greek word for “knuckle.” In fact, if you go to a butcher shop, you can order a “knuckle bone” for soups or for dog treats. For all first step is exposure and Anterior surface slopes downward from lateral to medial, 2. Points along the lateral and medial aspect of the distal femur at the level of the epicondylar axis deter-mined the width of the femur after the simulated resec-tion. Because of the anatomy of the distal femur, only surgical treatment is indicated to stabilize the fracture. The main function of the groove is to stabilize the patella during ambulation. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Distal femoral fractures involve the femoral condyles and the metaphyseal region and are often the result of high energy trauma such as motor vehicle accidents or a fall from a height. sTEA is marked in the picture on the right, connecting the lateral epicondyle and medial sulcus. Immediately lateral to the head is the neck that connects the head with the shaft. Femur – Distal End. Medial wall inclines 25 degrees. In young adults, this force is typically the result of high-energy trauma such as motor vehicle collision or fall from a height. extension This cartilage cushions the knee joint and allows for your knee to bend. the anterior surface of the femur, over the patellar will align with the femoral shaft. for more anatomy content please follow us and visit our website: www.anatomynote.com. Russell using a femoral distractor placed on the lateral side of Distal Femur – anterior view medial lateral Lateral Epicondyle right femur 39. The femur (/ ˈ f iː m ər /, pl. Most common types of distal femur fractures: Transverse fractures; Comminuted fractures ; Intra-articular fractures ; Clinically Relevant Anatomy The femur, also known as the thigh bone, is the longest bone in the body. patellar groove anteriorly and the intercondylar notch Most distal femur fractures are the result of a severe axial load with a varus, valgus, or rotational force. Infection & Critical Care. 33-E/2 Epiphysiolysis with metaphyseal wedge, SH II. Distal femur. This area comprises the distal 10 to 15 cm of the femur. Spell. for more anatomy content please follow us and visit our website: www.anatomynote.com. PCA is angle between sTEA and PCL (not marked in the picture) - "A study of anatomy of distal femur pertaining to total knee replacement: an analysis, conclusions and recommendations" 12 Recently, Mahfouz et al5 described many differences in the anatomy of the distal femur between men and women. parapatella approach or minimally invasive split patella tendon. Distal End. The supracondylar region (distal metaphysis) flares medially greater than laterally in the coronal plane and broadens laterally greater than medially in the sagittal plane. transverse plane. c, distal portion ofthe right femur of some verj large bird, seen on antero-oblique view. Distal femur. The medial condyle extends more distally and is more convex than the lateral femoral condyle. Lateral wall inclines 10 degrees 3. the coronal plane (i.e., flexion and extension) should be such that the plate above can be done by a mini invasive technique as described by METHODS: Magnetic resonance imaging (MRI) was obtained from 1522 patients (1298 females and 224 males) with end-stage knee osteoarthritis prior to TKA. June 7, 2016 Anatomy. The femoral head projects medially and superiorly and articulates with the acetabulum of the pelvis to form the hip joint.
