Figure 1. Femur and Patella. The femur is The one bone of the thigh location. It articulates superiorly While using the hip bone on the hip joint, and inferiorly Using the tibia for the knee joint. The patella only articulates Using the distal stop with the femur.
Within the back again on the knee the popliteal artery operates throughout the popliteal fossa towards the popliteal muscle mass the place it divides into anterior and posterior tibial arteries.[43]
These variables could result in in an imbalance in the muscle pull that functions about the patella, causing an irregular tracking from the patella which allows it to deviate too considerably towards the lateral facet in the patellar floor around the distal femur.
Together with the knee prolonged, it adducts the thigh and flexes the hip. The pectineus has its origin around the iliopubic eminence laterally on the gracilis and, rectangular in form, extends obliquely to attach right away driving the lesser trochanter and down the pectineal line along with the proximal Portion of the linea aspera within the femur. It's a flexor in the hip joint, and an adductor plus a weak medial rotator on the thigh. The adductor brevis originates around the inferior ramus of your pubis under the gracilis and stretches obliquely beneath the pectineus all the way down to the upper 3rd with the linea aspera. Aside from staying an adductor, It is just a lateral rotator and weak flexor with the hip joint.[twenty]
The proximal tibia is made up of the expanded medial and lateral condyles, which articulate With all the medial and lateral condyles from the femur to form the knee joint. Concerning the tibial condyles could be the intercondylar eminence. Within the anterior side with the proximal tibia would be the tibial tuberosity, that is continual inferiorly Along with the anterior border from the tibia.
Legs are utilized for standing, numerous varieties of human motion, recreation for example dancing, and here represent a significant portion of an individual's mass. Evolution has led towards the human leg's progress into a system precisely tailored for effective bipedal gait.
Bones with the leg The major bones from the leg are the femur (thigh bone), tibia (shin bone), and adjacent fibula, and they're all very long bones. The patella (kneecap) is definitely the sesamoid bone in front of the knee. The majority of the leg skeleton has bony prominences and margins which might be palpated and many serve as anatomical landmarks that outline the extent from the leg.
The possibility of damaging our lower extremities are going to be minimized by possessing knowledge about some functions connected with lower leg injury and producing a correct sort of working, such as not over-pronating the foot or overusing the legs.

The muscles with the thigh could be categorised into three groups according to their site: anterior and posterior muscles as well as adductors (about the medial facet). All the adductors apart from gracilis insert within the femur and act within the hip joint, and so functionally qualify as hip muscles.
These muscles and their fatty tissue function as cushions that transmit the burden of the body downward. In general, the foot is really a purposeful entity.[34]
The muscles linked to swing have the lower limb forwards, backwards, sideways or upwards even though the other limb is in help.
Ordinarily, the massive joints with the lower limb are aligned inside of a straight line, which signifies the mechanical longitudinal axis with the leg, the Mikulicz line. This line stretches within the hip joint (or maybe more precisely the head of the femur), with the knee joint (the intercondylar eminence in the tibia), and right down to the center in the ankle (the ankle mortise, the fork-like grip amongst the medial and lateral malleoli). While in the tibial shaft, the mechanical and anatomical axes coincide, but while in the femoral shaft they diverge 6°, resulting in the femorotibial angle of 174° in a leg with normal axial alignment.
People of our products and solutions should feel confident, secure, and integrated with their prosthetic leg, knee, ankle, foot or limb method; in a position to Reside their existence because they picture. The individual’s lower limb performs just like a organic extension in the human entire body.
