Femur Essays

plateau fracture is a break in the bone that forms the bottom of your knee joint (tibia or shinbone). The lower end of your thighbone (femur) forms the upper surface of your knee joint. The top of the tibia has a flat, smooth surface (tibial plateau). This part of your shinbone is made up of softer bone than the shaft of your shinbone. If a strong force drives your femur down into your tibial plateau, it can cause the tibial plateau to collapse or break away at the edges. A displaced tibial plateau

The Function of the First Ray The first ray plays a vital part in supporting the structural integrity of the foot and altered biomechanics of this structure may lead to the formation of foot pathologies (Glasoe et al., 1999). The axis of the first ray is deviated forty-five degrees from the saggital and frontal planes (Hetherington, 1994; Hicks, 1954). The motion associated with this axis includes plantar flexion in eversion and adduction in supination and also dorsiflexion coupled with inversion

Patellar Dislocation and Subluxation With Phase I Rehab Patellar dislocation and patellar subluxation are injuries that happen when the kneecap (patella) slips out of its normal position in a groove in the end of the thighbone (femur). In a patellar dislocation, the kneecap slips all the way out of the groove. In a patellar disoclation, it slips partly out of the goove. CAUSES This injury may be caused by: A hit to the knee. Firmly pointing the foot outward and bending the knee with the

Introduction 2. Femur is largest and longest bone in human body. Femur is strongest in compression when compared to the tension and shear. The structure of femur is anisotropy , but for analytical calculation purpose .It is considered as is tropic material. The properties of femur aften compared to the man-made materials. The femur mechanical properties are very potent strong, and impressive. Biomechanics is the application of mechanical principles on living organisms. The study of bio mechanical

Adult Proximal Humerus Locking Plate for the Treatment of a Pediatric Subtrochanteric Femoral fracture: A Case study Pediatric subtrochanteric femur fractures are rare injuries that lead to a high level of satisfactory outcomes after nonoperative treatment in young children and operative treatment in older children and adolescents.1–8 Only limited data have been published on operative treatment of these injuries with reported healing rates of 100% after intramedullary nailing with elastic or rigid

I went up for a layup and got pushed hard in the back. When I came down, I felt my knee buckle and immediately knew something wasn’t right. The sound it made was alarming, proving to be a serious injury - a fractured femur. It was my junior year and I was looking forward to playing basketball and starting to train for the next football season. In my long recovery from this injury, I learned the traits of acceptance, hard work, determination, and vocal leadership. A few months before the injury

a ball-and-socket joint, the head of the femur articulates with the acetabulum of the pelvis. With how the head is oriented in the socket, the joint is able to withstand tremendous amounts of pressure and allows it to be a strong and stable portion of the human anatomy. The design of the hip is actually very flexible and allows for a wide range of movements in different axis. Anatomically, the “ball” portion of the joint consists of the head of the femur. The “socket”, or acetabulum, is a bit more

Total Knee Arthroplasty (TKA) involves the parameter of the distal femur size and proximal tibia size. An accurate of measurements can improve the physiology function of knee after implant and the tissue surrounding the knee. Most of the prosthesis size commercially is following Western measurement therefore the accuracy of having prosthesis for Asian is low compare to others. The probability of mismatch of prosthesis is high in Asian population. A good prosthesis shown the significant in pain relief

“The Missing Femur at the Mitla Fortress and its Implications.” Feinman, Gary M.; Nicholas, Linda M.; Baker, Lindsey C. Antiquity. Dec2010, Vol. 84 Issue 326, p1089-1101. 13p. Archeologists have made many discoveries to support the idea that femora held very special meaning to the Aztecs and Mayas during pre-Hispanic Mesoamerica. Although the use of it greatly differs between the two civilizations, many believed it held each individuals power, whether that power was good or bad (Klein 2002; Marcus

\section{Introduction} \subsection{Motivation} Amputation, is surgically removing all or a part of the limb or arm, leg, foot, hand, toe or finger. The amputation that occurs through the femur is a transfemoral or above knee amputation. Transfemoral amputees form the second largest group of amputees in the world \cite{oandp}. Hence, transfemoral prosthesis is an important field of study. Transfemoral amputation is mostly found in oncology patients. For vascular disease, severe disease affecting

like walking, squatting and stair climbing. The bones that form the hips are the femur or far bone and pelvis. The top of the femur shape like a ball called femoral head that fits into a round socket on the side of the pelvis. This socket is named as acetabulum. The femoral head is attached to the rest of the femur by a short section of a bone called femoral neck. A large bone protruding out from the top of the femur which located next to the femoral neck is called the greater trochanter. Large and

of soldiers were killed and injured. Some of these injuries were mid-shaft femur fractures. A Welsh surgeon Dr. Hugh Owen Thomas, but it was introduced by Sir Robert Jones during the war, (White, 2011). The introduction of the traction splint (or the Thomas splint) made a significant impact on reducing mortality due to compound femur fractures, (White, 2011). Since then it evolved and became very significant in managing femur fractures. There are a variety of traction splints in terms of appearance

Traction splint (device) is used in compound (open) femur fractures, to help align the broken bone as well as reduce the level of pain. The first practical traction splint was created in 1975 by British orthopaedic surgeon, Hugh Owen Thomas. His family was bonesetter from Welesh and this was inherited by Thomas. The device was introduced to the British and French armies by Sir Robert Jones nephew Thomas in 1915. Thomas had previously offered the device to the French army during the Franco-Prussian

leg bud in the 4th week. The formation of femur, tibia and fibula occurs in the 6th week. The knee joint embryologically arises from blastemal cells with the formation of the patella, cruciate ligaments and meniscus in the 7th week.22 Knee joint is formed by two condylar joints between the femoral condyles (medial and lateral both) and the corresponding tibial condyles. Knee joint also has a gliding joint between the patella and the corresponding femur articular surface. The fibula is not involved

The Patellofemoral and knee joints would be open, but she has small bone spurs projecting from the patella, going posteriorly towards the femur and superiorly from the tibia towards the femur. The patient is under rotated because the lateral condyle is not completely superimposed over the medial condyle of the femur. The medial condyle is the one that appears “smaller” because it is closest to the image receptor. The lateral condyle is more posterior than the medial so the patient

Abstract— The main aim is to develop the three dimensional solid finite element model of knee joint to predict stress in its individual components (Femur, Tibia, Menisci and Patella) and to determine the load carried by a pre – selected ligamentous tissue. This work assists to analyze a knee response to a dynamically applied load. This simulated analysis will serve to be an alternative approach to destructive tests and intrusive procedures and helps to achieve closer simulation to reality. The main

or constructions surrounding the hip joint. It joins legs with torso of the body, the thigh bone femur swivels within the joint made up of pelvic bones, this structure is like a socket and contains area and really much less fluid in it. This socket like structure is known as acetabulum. Any damage or infection fills this space with fluid or blood which restricts the free motion of the head of the femur causing anguish, stiffness, and even locking of the joint. Inflammation, swelling, redness and warmth

bones which are the femur, tibia and patella (Taylor, n.d.). There are two rounded, convex processes which are known as condyles on the distal end of the femur. The distal end of the femur meets two rounded, concave condyles at the proximal end of the tibia (Tyalor, n.d.). A thick, triangular bone which is known as patella lies anterior surface between the femur and tibia. In each knee joint, there is two pieces of C-shaped cartilage which lies between the surfaces of the femur and tibia. The lateral

What is Federalism? Federalism is a system of government in which a written constitution divides the powers of government on a territorial basis, between a central government and several regional governments usually called states or provinces. Federalism works in some cases but not always. There are certain factors Federalism can’t always meet. Federalism sometimes don’t work because of the central government or the states. But, Federalism allows local action in matters of local concern and national

especially in the secondary spongy areas and reduced the number of bone resorption pouches and OC. H-HE can also recover the Tb.N, Tb.Th and Tb.Sp just as positive group. CONCLUSION This study has demonstrated that H-HE can effectively increase BMD of the femurs, increased Tb.N and Tb.Th, but reduced Tb.Sp, all of which contribute to the treatment of
