The massive growth uncovered over the medial aspect from the distal tibia may be the medial malleolus (“little hammer”). This sorts the big bony bump discovered over the medial aspect from the ankle area. Both of those the smooth area on The within from the medial malleolus and the smooth spot for the distal end of the tibia articulate Along with the talus bone of the foot as A part of the ankle joint.
The patella articulates While using the patellar floor on the femur and therefore prevents rubbing of your muscle mass tendon in opposition to the distal femur. The patella also lifts the tendon clear of the knee joint, which raises the leverage ability in the quadriceps femoris muscle as it functions through the knee. The patella won't articulate While using the tibia.
These elements may possibly cause within an imbalance during the muscle mass pull that acts over the patella, leading to an irregular monitoring on the patella that permits it to deviate as well much towards the lateral facet from the patellar area to the distal femur.
The muscles from the leg and thigh is going to be explained beneath a few headings linked to their operate in aid, swing and propulsion.
For the duration of extension in the knee, the quadriceps femoris muscle pulls the patella equally superiorly and laterally, Along with the lateral pull larger in Females due to their huge Q-angle. This can make Gals extra vulnerable to creating patellofemoral syndrome than Guys. Usually, the massive lip to the lateral aspect from the patellar area on the femur compensates for your lateral pull on the patella, and so aids to maintain its appropriate tracking.
The patella is actually a sesamoid bone located in just a muscle mass tendon. It articulates Together with the patellar surface area to the anterior side with the distal femur, thus preserving the muscle mass tendon from rubbing in opposition to the femur.
The epicondyles supply attachment for muscles and supporting ligaments of the knee. The adductor tubercle is a little bump located for the exceptional margin with the medial epicondyle. Posteriorly, the medial and lateral condyles are separated by a deep depression called the intercondylar fossa. Anteriorly, The sleek surfaces on the condyles sign up for together to type a large groove called the patellar floor, which delivers for articulation with the patella bone. The combination from the medial and lateral condyles With all the patellar surface area presents the distal conclusion of the femur a horseshoe (U) condition.
insignificant indentation on The pinnacle of the femur that serves as the site of attachment with the ligament to The pinnacle of the femur
The posterior 50 percent on the foot is shaped by seven tarsal bones ([hyperlink]). Essentially the most outstanding bone may be the talus. This has a relatively sq.-formed, upper surface area that articulates Using the tibia and fibula to variety the ankle joint. A few regions of articulation sort the ankle joint: The superomedial surface area on the talus bone articulates Together with the medial malleolus on the tibia, the highest on the talus articulates Along with the distal conclusion with the tibia, along with the lateral aspect on the talus articulates With all the lateral malleolus in the fibula.
The arches of your foot Participate in a significant function In this particular shock-absorbing capacity. When weight is applied to the foot, these arches will flatten somewhat, Consequently absorbing Electrical power. When the load is taken off, the arch rebounds, giving “spring” into the phase. The arches also serve to distribute body weight aspect to facet and to possibly close from the foot.
A bunion may additionally be brought on by prolonged pressure over the foot from pointed shoes by using a slender toe box that compresses the big toe and pushes it toward the 2nd toe.
These elements might trigger in an imbalance during the muscle mass pull that functions about the patella, leading to an abnormal monitoring of your patella that enables it to deviate way too much toward the lateral facet of your patellar area over the distal femur.
Usually, the massive joints of your lower limb are aligned inside of a straight line, which signifies the mechanical longitudinal axis on the leg, the Mikulicz line. This line stretches within the hip joint (or maybe more specifically The top in the femur), with the knee joint (the intercondylar eminence from the tibia), and down to the middle of your ankle (the ankle mortise, the fork-like grip concerning the medial and lateral malleoli). In the tibial shaft, the mechanical and anatomical axes coincide, but in the femoral shaft they diverge six°, causing the femorotibial angle of 174° in a very leg with usual axial alignment.
tarsal bone that articulates posteriorly With all the talus bone, laterally Together with the cuboid bone, lower limb supports and anteriorly With all the medial, intermediate, and lateral cuneiform bones
