Determine one. Femur and Patella. The femur is The only bone from the thigh area. It articulates superiorly With all the hip bone on the hip joint, and inferiorly Along with the tibia at the knee joint. The patella only articulates Using the distal conclude with the femur.
small, well known ridge functioning among the better and lesser trochanters over the posterior side of your proximal femur
The distal conclude on the fibula varieties the lateral malleolus, which sorts the effortlessly palpated bony bump within the lateral aspect in the ankle. The deep (medial) side of your lateral malleolus articulates Along with the talus bone on the foot as part of the ankle joint. The distal fibula also articulates Together with the fibular notch of your tibia.
smooth, articulating area that sorts the distal and posterior sides of the lateral expansion of the distal femur
The patella articulates with the patellar surface from the femur and therefore stops rubbing in the muscle tendon in opposition to the distal femur. The patella also lifts the tendon from the knee joint, which enhances the leverage ability of your quadriceps femoris muscle mass mainly because it functions over the knee. The patella won't articulate Along with the tibia.
The proximal close from the tibia is considerably expanded. The two sides of this growth variety the medial condyle from the tibia plus the lateral condyle of the tibia. The tibia does not have epicondyles. The highest area of each condyle is easy and flattened.
The large toe has two phalanx bones, the proximal and distal phalanges. The remaining toes all have proximal, middle, and distal phalanges. A joint concerning adjacent phalanx bones is termed an interphalangeal joint.
The sacroiliac joint amongst the sacrum as well as ilium on the innominate bone is usually a joint that is part synovial and element fibrous. The ear-formed irregular joint surfaces, to the posterior medial part of the ilium and also the upper lateral aspect on the sacrum, healthy intently.
The posterior 50 % from the foot is shaped by 7 tarsal bones ([website link]). Essentially the most top-quality bone may be the talus. This has a comparatively square-formed, higher floor that articulates Together with the tibia and fibula to variety the ankle joint. Three regions of articulation variety the ankle joint: The superomedial surface in the talus bone articulates Along with the medial malleolus of lower limb supports the tibia, the very best on the talus articulates While using the distal finish in the tibia, plus the lateral side from the talus articulates Together with the lateral malleolus with the fibula.
The proximal team of tarsal bones features the calcaneus and talus bones, the navicular bone is intermediate, as well as the distal team is made of the cuboid bone furthermore the medial, intermediate, and lateral cuneiform bones.
Since the hips are wider compared to knee region, the femur has a diagonal orientation throughout the thigh, in contrast into the vertically oriented tibia on the leg (Figure two). The Q-angle is really a evaluate of how considerably the femur is angled laterally from vertical. The Q-angle is Usually ten–15 levels, with females commonly possessing a bigger Q-angle due to their broader pelvis.
Stop by This website to complete a Digital knee substitution surgical treatment. The prosthetic knee parts need to be properly aligned to operate thoroughly. How is this alignment ensured?
lateral, expanded region on the proximal tibia that features the smooth surface that articulates Together with the lateral condyle of your femur as A part of the knee joint
The epicondyles deliver attachment for muscles and supporting ligaments of your knee. The adductor tubercle is a little bump Positioned for the remarkable margin on the medial epicondyle. Posteriorly, the medial and lateral condyles are separated by a deep depression called the intercondylar fossa. Anteriorly, The graceful surfaces with the condyles be part of collectively to type a wide groove known as the patellar floor, which supplies for articulation With all the patella bone. The combination of the medial and lateral condyles While using the patellar floor provides the distal end of your femur a horseshoe (U) form.
