Determine one. Femur and Patella. The femur is The only bone from the thigh region. It articulates superiorly Using the hip bone for the hip joint, and inferiorly Using the tibia at the knee joint. The patella only articulates with the distal conclude in the femur.
rounded, proximal finish of the femur that articulates While using the acetabulum with the hip bone to kind the hip joint
Check out this movie to look at how a fracture from the mid-femur is surgically fixed. How are the two parts in the damaged femur stabilized for the duration of surgical repair of the fractured femur?
Femur and Patella The femur is the single bone of your thigh area. It articulates superiorly While using the hip bone in the hip joint, and inferiorly with the tibia for the knee joint. The patella only articulates Along with the distal end in the femur.
During extension from the knee, the quadriceps femoris muscle pulls the patella both equally superiorly and laterally, Along with the lateral pull larger in Girls because of their significant Q-angle. This would make Girls a lot more at risk of developing patellofemoral syndrome than Adult males. Commonly, the big lip around the lateral facet with the patellar surface area from the femur compensates with the lateral pull to the patella, and thus helps to take care of its appropriate tracking.
The narrowed location beneath The top would be the neck on the femur. That is a prevalent place for fractures of your femur. The bigger trochanter is the massive, upward, bony projection Found earlier mentioned the base of your neck. Many muscles that act throughout the hip joint attach to the greater trochanter, which, because of its projection from the femur, presents supplemental leverage to these muscles. The greater trochanter is usually felt just below the pores and skin about the lateral side of your higher thigh.
The iliotibial tract (also referred to as the fascia lata) is usually a band of dense fascia that extends throughout the hip and knee on the lateral aspect of the thigh. In standing, The stress in a small muscle mass, generally known as the tensor fascia lata, which originates around the anterior remarkable spine with the ilium and inserts in to the iliotibial tract, retains the hip and knee extended, with the help of your gluteus maximus, the big superficial muscle mass from the buttock (Determine eight.5b).
minimal indentation on The top from the femur that serves as the site of attachment for the ligament to the head of the femur
tiny ridge operating between the larger and lesser trochanters within the anterior facet in the proximal femur
A leg is considered straight when, Along with the feet brought jointly, both the medial malleoli in the ankle plus the medial condyles of the knee are touching. Divergence from the normal femorotibial angle is termed genu varum if the middle of your knee joint is lateral to the mechanical axis (intermalleolar distance exceeds 3 cm), and genu valgum if it is medial on the mechanical axis (intercondylar length exceeds five cm). These disorders impose unbalanced loads on the joints and stretching of either the thigh's adductors and abductors.[12]
Treatment method usually entails stopping the exercise that provides knee suffering for any stretch of time, accompanied by a gradual resumption of action. Suitable strengthening with the quadriceps femoris muscle mass to proper for imbalances can also be important to help reduce reoccurrence.
These variables may possibly lead to in an imbalance during the muscle mass pull that acts on the patella, causing an irregular monitoring of your patella which allows it to deviate as well much towards the lateral aspect of the patellar surface area around here the distal femur.
Ordinarily, the massive joints of your lower limb are aligned inside of a straight line, which signifies the mechanical longitudinal axis with the leg, the Mikulicz line. This line stretches with the hip joint (or even more exactly the head from the femur), through the knee joint (the intercondylar eminence of the tibia), and all the way down to the middle on the ankle (the ankle mortise, the fork-like grip amongst the medial and lateral malleoli). Inside the tibial shaft, the mechanical and anatomical axes coincide, but inside the femoral shaft they diverge 6°, causing the femorotibial angle of 174° in a very leg with standard axial alignment.
The pelvis types the url amongst the vertebral column plus the thigh with the transmission of the human body weight downwards in the trunk towards the hip and knee joints, and on for the ft.
