1、The FemurAnatomy of the femur.What is the femur/ thigh bone?The femur is the longest and strongest bone in the body. It is capable of walking and jumping.What does the femur do?The entire femur bone supports the upper body and distributes the energy to the feet.Where is the femur/ thigh bone?It form

2、s part of the hip joint (at the acetabulum) and part of the knee joint; which it is located above.What are the components of the femur?*Also known as protuberancesThe Head, greater trochanter, lesser trochanter, body and lower extremity*The different components help to break down the whole bone.Musc

3、les Around the thigh boneMUSCLES FOR SPECIFIC MOVEMENTS*Anterior muscles are the quardriceps group.*Rectus femoris is the largest muscle of the quardriceps group. It runs down the iliac spine to the tibia.* Other 3 quards muscles : Vastus medialis, Vastus Intermedius and Vastus Lateralis.Originate a

4、long the inside, outside and back of upper femur and insert into patellar tendon. They flex the hip and extend the knee.*Sartorius begins at upper iliac spine and runs down to the inner surface of tibia.Longest muscle in our body. Helps to extend the knee on the upper phase of plie and complete a de

5、veloppe movement, it also has a role in turnout and helps to keep supporting leg straight.* The adductors (aka inner thigh) begin along different aspects of pubis bone and attach along different aspects of medial femur. They are the adductor longus, adductor brevis and adductor magnus, pectineus and

6、 gracilis. Adduct the thigh and also have the ability to bring your leg to the front and back at lower levels. They are important for holding their legs in external rotation. Eg first position releve.* Biceps femoris originates along the ischial tuberosity and femur; and inserts into the lateral tib

7、a and fibula. Activates strongly in arabesque movements.* The semitendinosus and semimembranosus originate at the ischial tuberosity and insert into the medial tibia. All the hamstring muscles flex the knee and extend the hip.* Gluteus maximus originates off posterior surface of the ilium, sacrum an

8、d coccyx bones and inserts into femur. The gluteus maximus and hamstrings initiate every swing kick to the back, battlement and arabesque.Limitations of the hip* If you are performing a devloppe-type movement, the head of the Femur must glide downward & cont. to turn out.Injuries (1)*Because the fem

9、ur is such a strong bone, it must take tremendous force to actually cause a fracture. Circumstances such as falling from a height may cause a femur fracture.3 Categories of Femur fracture.Proximal femur fracture upper portion of femurFemoral shaft fracture Severe injury. Needs medical treatment / op

10、erationSupracondylar fracture Unusual injury above the knee joint.Injuries (2)Injuries involving muscles around thefemur.Quadriceps strain:-Tearing of muscle fibres, most commonly occurring in the Rectus Femoris-Most common symptom is pain, there may be swelling around the site of the injury and slight discolouration.Treatment: RICEPrevention: Having a good warm up & stretching.Hamstring injuries:-Usually occur with sudden running and jumping. Pop sound could be heard. For severe injury, swelling and blue-bl
