small ridge functioning down the lateral facet with the tibial shaft; for attachment on the interosseous membrane amongst the tibia and fibula
compact ridge jogging down the lateral aspect in the tibial shaft; for attachment from the interosseous membrane between the tibia and fibula
The distal end on the fibula forms the lateral malleolus, which varieties the effortlessly palpated bony bump to the lateral side with the ankle. The deep (medial) side with the lateral malleolus articulates Using the talus bone of your foot as Portion of the ankle joint. The distal fibula also articulates While using the fibular notch in the tibia.
Together with the knee prolonged, it adducts the thigh and flexes the hip. The pectineus has its origin to the iliopubic eminence laterally into the gracilis and, rectangular in condition, extends obliquely to connect straight away behind the lesser trochanter and down the pectineal line and also the proximal A part of the linea aspera over the femur. This is a flexor from the hip joint, and an adductor in addition to a weak medial rotator on the thigh. The adductor brevis originates around the inferior ramus of your pubis under the gracilis and stretches obliquely below the pectineus right down to the upper 3rd from the linea aspera. Aside from becoming an adductor, It's really a lateral rotator and weak flexor of your hip joint.[twenty]
The posterior tibial types a direct continuation of your popliteal artery which enters the flexor compartment with the lower leg to descend guiding the medial malleolus the place it divides in to the medial and lateral plantar arteries, of which the posterior branch offers rise on the fibular artery.[43]
The iliohypogastric (T12-L1) and ilioinguinal nerves (L1) emerge within the psoas significant close to click here the muscle mass's origin, from in which they operate laterally downward to move anteriorly earlier mentioned the iliac crest involving the transversus abdominis and abdominal inside oblique, after which operate previously mentioned the inguinal ligament. Both nerves give off muscular branches to both equally these muscles.
The Q-Angle The Q-angle is a measure of the quantity of lateral deviation with the femur from the vertical line from the tibia. Adult ladies have a bigger Q-angle because of their wider pelvis than adult males.
The lesser trochanter is a little, bony prominence that lies over the medial element of the femur, slightly below the neck. An individual, impressive muscle mass attaches on the lesser trochanter. Jogging between the better and lesser trochanters about the anterior facet of the femur may be the roughened intertrochanteric line. The trochanters are also related on the posterior side in the femur with the much larger intertrochanteric crest.
The acetabulum lies in the side in the pelvis which is a deep, outwards-struggling with cup surrounded by a rim of fibrocartilage, known as a labrum. The head of the femur types the ball, which can be two-thirds of a sphere. Once the ball is inside the socket, the labrum curves inwards over and above the equator of The top in the femur to grip it and support to hold it in position.
most lateral with the three cuneiform tarsal bones; articulates posteriorly While using the navicular bone, medially Along with the intermediate cuneiform bone, laterally Using the cuboid bone, and anteriorly While using the third metatarsal bone
Within the knee joint, There's two even more crucial ligaments. These are definitely attached for the centre in the tibial plateau and move upwards to connect inside the intercondylar notch from the femur (Appendix I). They seem to cross one another and so They're known as the cruciate ligaments (Determine 8.
We develop and manufacture products meant to offer you folks the best possible mobility, purpose, convenience and cosmesis following amputation or other pathology.
broad groove around the lateral side of the distal tibia for articulation with the fibula at the distal tibiofibular joint
Like the upper limb, the lower limb is split into a few locations. The thigh is that portion of the lower limb located involving the hip joint and knee joint. The leg is especially the area amongst the knee joint along with the ankle joint. Distal on the ankle could be the foot. The lower limb has thirty bones. These are definitely the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges. The femur is The one bone with the thigh.
