The distal end of the femur is where it connects with the patella (knee cap) and the bones of the lower leg, the tibia, and fibula. This area is the largest and most active physeal system in the body, contributing almost 70% of the length of the femur and 40% of the length of the entire leg. The distal femoral anatomy of Australopithecus Am J Phys Anthropol. 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 … the screw is placed, flexion and extension can still be adjusted, When viewing the distal surface of the femur end on, the condyles are wider posteriorly, thus forming a trapezoid. Flashcards. Think of this when drilling top and bottom of drill holes. At least two distal screws to control X ray film of distal femur fracture. - collateral ligaments originate from distal femoral epiphysis & insert on proximal tibial epiphysis, w/ exception of superficial portion of MCL, … Finally control the rotational position of the blade in 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. On 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.

(There are four types of bone: long bones, short bones, flat bones, and irregular bones.) Suitable for all fractures except with fracture Learn vocabulary, terms, and more with flashcards, games, and other study tools. Check length and rotation, then attach side plate with at least 8 proximal (See description.) The head forms a ball-and-socket joint with the hip (at the acetabulum), being held in place by a ligament (ligamentum teres femoris) within the socket and by strong surrounding ligaments. Kumar K(1), Sharma D(2). The main function of the groove is to stabilize the patella during ambulation. Anatomy. In young adults, this force is typically the result of high-energy trauma such as motor vehicle collision or fall from a height. plate-barrel (screw) angle is 95 degrees, as in the blade plate. transverse plane. 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. unlike the blade plate. 33.1 ). extension The lower end of the femur, called the distal end, articulates with the tibia of the lower leg. Insert at under knee to flex slightly(30-40 degrees), allows easier entry. 11, 12 It is the last epiphysis to fuse in the adult. along with increasing the risk of notch penetration.

Distal Femur – anterior view medial lateral right femur 38. Placing lag screws away from entry points of individual implants. This accounts for the physiologic valgus of the femur. The end of the bone is covered with a smooth surface called articular cartilage. The hip joint capsule inserts along the intertrochanteric line. The distal femur is the area of the leg just above the knee joint. Distal femur. Any possible dangers should … Trochlear Surface of the Femur . Onthe lateral view the shaft is aligned with the anterior half ofthe lateral condyle. Distal End. Knowledge of anatomy is crucial during placement of plates, which are often designed to be positioned along the anterior distal femur, approximating the border of the articular surface while avoiding intra-articular penetration of screws within the notch posteriorly or the trochlea anteriorly.

No. The supracondylar region (distal metaphysis) flares medially greater than laterally in the coronal plane and broadens laterally greater than medially in the sagittal plane. Kumar K(1), Sharma D(2). This area is the largest and most active physeal system in the body, contributing almost 70% of the length of the femur and 40% of the length of the entire leg. The distal femur is not an area routinely or solely used to determine gender. The articular portion of the anterior surface of the distal femur, which articulates with the patella, has been referred to variously as the patellar facets of the femur, the patellar groove, the femoral sulcus, and the trochlea. Insert third K-wire into the lateral posteriorly. Distal femur. Fig. Place K wire The distal femur's secondary center of ossification first appears in the forming fetus at approximately 9 weeks, and at the birth of a full-term gestation, it is the only epiphyseal ossification center present. Match. used exposure. On average, the anatomic axis (the angle between the shaft of the femur and the knee joint) has a valgus angulation of 9 degrees (range, 7 to 11 degrees) (, Deforming forces from muscular attachments cause characteristic displacement patterns (. mal-rotation of the blade will result in flexion or extension The To prevent a Fracture of the Distal Femur, individuals should be careful and consciously aware, while performing any physical activities, such as sports, or even some normal daily activities that could lead to situations involving accidents. 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. Distal Femur Fractures with Retrograde Surgical Fixation with Intramedullary Nail. Femur, upper bone of the leg or hind leg. The anatomy and functional axes of the femur. Patients typically are unable to ambulate with pain, swelling, and variable deformity in the lower thigh and knee. Lateral approach most commonly femoral condyle distal to the marked blade entry site. the lateral view the shaft is aligned with the anterior half of It has rounded edges on either side of the knee joint, known as the condyles. It is the largest bone in the body and is the only bone in the upper leg. Because of the anatomy of the distal femur, only surgical treatment is indicated to stabilize the fracture.
