Center in the 3 cuneiform tarsal bones; articulates posteriorly with the navicular bone, medially Using the medial cuneiform bone, laterally With all the lateral cuneiform bone, and anteriorly with the second metatarsal bone
The epicondyles offer attachment for muscles and supporting ligaments of your knee. The adductor tubercle is a little bump Positioned with the remarkable margin of the medial epicondyle. Posteriorly, the medial and lateral condyles are divided by a deep depression called the intercondylar fossa. Anteriorly, The sleek surfaces on the condyles join together to kind a broad groove known as the patellar area, which offers for articulation Together with the patella bone. The mix with the medial and lateral condyles with the patellar surface offers the distal finish of the femur a horseshoe (U) shape.
These bones are definitely the medial cuneiform, the intermediate cuneiform, plus the lateral cuneiform. Every of those bones features a broad remarkable surface and a slim inferior surface area, which collectively generate the transverse (medial-lateral) curvature in the foot. The navicular and lateral cuneiform bones also articulate Together with the medial aspect on the cuboid bone.
The muscles from the leg and thigh might be described less than a few headings connected with their function in support, swing and propulsion.
The patella articulates Along with the patellar area of the femur and thus prevents rubbing from the muscle tendon towards the distal femur. The patella also lifts the tendon far from the knee joint, which boosts the leverage electricity on the quadriceps femoris muscle mass since it functions over the knee. The patella isn't going to articulate With all the tibia.
The patella is really a sesamoid bone Found in just a muscle tendon. It articulates with the patellar floor within the anterior facet in the distal femur, therefore preserving the muscle mass tendon from rubbing towards the femur.
The Q-Angle The Q-angle is usually a evaluate of the quantity of lateral deviation on the femur with the vertical line with the tibia. Grownup ladies have a larger Q-angle due to their wider pelvis than Grownup males.
To the lateral facet in the distal tibia is a wide groove known as the fibular notch. This region articulates with the distal conclusion in the fibula, forming the distal tibiofibular joint.
deep despair to the posterior aspect from the distal femur that separates the medial and lateral condyles
The proximal team of tarsal bones incorporates the calcaneus and talus bones, the navicular bone is intermediate, as well as the distal team contains the cuboid bone furthermore the medial, intermediate, and lateral cuneiform bones.
Functionally, the muscles in the leg are possibly extensors, chargeable for the dorsiflexion in the foot, or flexors, chargeable for lower limb supports the plantar flexion. These muscles could also categorised by innervation, muscles provided because of the anterior subdivision from the plexus and people equipped through the posterior subdivision.[27] The leg muscles performing on the foot are known as the extrinsic foot muscles even though the foot muscles located in the foot are named intrinsic.[28]
This pathological fracture is especially seen in older people today, when osteoporosis has weakened the bone. read more This fracture can interrupt the primary blood offer to The pinnacle from the femur plus the bone may fall short to unite (avascular necrosis).
The 4 lumbricales have their origin about the tendons of the flexor digitorum longus, from the place they extend on the medial side on the bases of the first phalanx of digits two-five. Aside from reinforcing the plantar arch, they contribute to plantar flexion and transfer the 4 digits toward the large toe. They are really, in contrast to your lumbricales from the hand, relatively variable, sometimes absent and occasionally in excess of 4 are existing. The quadratus plantae arises with two slips from margins from the plantar surface area on the calcaneus which is inserted into your tendon(s) of the flexor digitorum longus, and is called the "plantar head" of this latter muscle. The 3 plantar interossei come up with their solitary heads about the medial aspect with the 3rd-fifth metatarsals and they are inserted over the bases of the main phalanges of these digits.
Patellofemoral syndrome might be initiated by many different will cause, together with individual variations in the shape and movement in the patella, a direct blow on the patella, or flat toes or inappropriate shoes click here that bring about excessive turning in or out in the ft or leg.
