A Fracture that occurs at the distal end of the femur bone, which includes the femoral condyles and the metaphysis.. Vascularised fibular grafts for reconstruction of the femur. The lower end of the femur, called the distal end, articulates with the tibia of the lower leg. A non-surgical treatment is a rare option. Outline : - Basic anatomy - Introduction - Type of fractures - Clinical features - Investigations - Treatment - Surgical techniques - Complications 3. 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. 1971 Jul;35(1):75-84. doi: 10.1002/ajpa.1330350109.

This area comprises the distal 10 to 15 cm of the femur. reconstruction of articular surface with lag screws if needed. It is larger than the upper extremity of femur , is somewhat cuboid in form, but its transverse diameter is greater than its antero-posterior; it consists of two oblong eminences known as the lateral condyle and medial condyle . Place K wire The distal end is marked by the presence of the medial and lateral condyles, which join with the tibia and patella, forming the knee joint. 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. Medial unlike the blade plate.

It is a trapezoidal shaped bone that makes up the top of your joint and sits just behind your knee cap. Created by. Test. Since most TKR systems require an initial cut of between 7 mm to 10 mm from the distal femur, 8 mm was chosen. In the elderly, the force may result from a minor slip or fall onto a flexed knee. Radiolucent table, small sand bag under Ensure 8 cortices proximal fixation The head forms a ball-and-socket joint with the hip (at the acetabulum), being held in place by a ligament within the socket and by strong surrounding ligaments. Distal femur. 12 Recently, Mahfouz et al5 described many differences in the anatomy of the distal femur between men and women. tissue irritation. will align with the femoral shaft. A blade not parallel to the joint will induce a varus or valgus under knee to flex slightly(30-40 degrees), allows easier entry.

Any possible dangers should … A bimodal age distribution exists, with a high incidence in young males from high-energy trauma, such as motor vehicle or motorcycle accidents or falls from a height, and a second peak in elderly women from minor falls. 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. Finally control the rotational position of the blade in For example, the distal end of the femur (the thigh bone) is the end down by the knee; the end more distant from the torso. flexion and extension. STUDY. 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. 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. Distal femoral fractures account for about 7% of all femur fractures. Femoral anteversion. A This study aimed to define the rotational anatomy of the distal femur and investigate its relationship with gender in osteoarthritic knees. The epiphyseal ossification center of the distal femur is usually present at birth in a full-term infant. The surgeon needs to be aware of the shape of the bone when planning surgery so that the implant matches the bone. 11. Distal Femur – anterior view medial condyle lateral condyle right femur 37.
