The posterior dorsal hip muscles are inserted on or straight below the better trochanter of the femur. The tensor fasciae latae, stretching with the anterior superior iliac spine down into the iliotibial tract, presses the head from the femur in to the acetabulum but in addition flexes, rotates medially, and abducts to hip joint. The piriformis originates over the anterior pelvic surface from the sacrum, passes through the higher sciatic foramen, and inserts around the posterior aspect of the tip of the greater trochanter. Inside a standing posture It's really a lateral rotator, but In addition, it assists extending the thigh. The gluteus maximus has its origin among (and close to) the iliac crest and also the coccyx, from exactly where 1 part radiates into your iliotibial tract and the opposite stretches right down to the gluteal tuberosity under the greater trochanter.
Inferiorly, the talus articulates Together with the calcaneus (heel bone), the biggest bone with the foot, which forms the heel. Overall body weight is transferred with the tibia for the talus to the calcaneus, which rests on the bottom. The medial calcaneus includes a outstanding bony extension known as the sustentaculum tali (“assistance to the talus”) that supports the medial aspect from the talus bone.
The posterior 50 % with the foot is fashioned by 7 tarsal bones (Determine (PageIndex four )). One of the most top-quality bone is the talus. This has a comparatively square-shaped, higher floor that articulates Along with the tibia and fibula to kind the ankle joint. Three parts of articulation kind the ankle joint: The superomedial surface of your talus bone articulates Together with the medial malleolus in the tibia, the top on the talus articulates With all the distal end of the tibia, as well as the lateral side of the talus articulates Along with the lateral malleolus from the fibula.
Femur and Patella The femur is the single bone of your thigh area. It articulates superiorly Along with the hip bone for the hip joint, and inferiorly While using the tibia within the knee joint. The patella only articulates While using the distal close with the femur.
tarsal bone that articulates posteriorly While using the calcaneus bone, medially Together with the lateral cuneiform bone, and anteriorly Using the fourth and fifth metatarsal bones
The patella (kneecap) is major sesamoid bone of your body (see Determine (PageIndex 1 )). A sesamoid bone is usually a bone that is definitely included to the tendon of the muscle where that tendon crosses a joint. The sesamoid bone articulates Along with the underlying bones to forestall damage to the muscle tendon due to rubbing versus the bones through movements of the joint. The patella is located in the tendon in the quadriceps femoris muscle, the big muscle of your anterior thigh that passes throughout the anterior knee to attach to your tibia.
medial, expanded area of your proximal tibia that includes The graceful surface that articulates Together with the medial condyle of the femur as Section of the knee joint
The elongated shaft from the femur includes a slight anterior bowing or curvature. At its proximal conclude, the posterior shaft has the gluteal tuberosity, a roughened place extending inferiorly through the bigger trochanter.
During extension of the knee, the quadriceps femoris muscle pulls the patella both superiorly and laterally, With all the lateral pull larger in Gals because of their click here substantial Q-angle. This would make Gals additional prone to establishing patellofemoral syndrome than Gentlemen. Generally, the big lip within the lateral side from the patellar surface of your femur compensates with the lateral pull to the patella, and therefore aids to maintain its proper monitoring.
small, knob-like, proximal conclude of your fibula; articulates With all the inferior element of the lateral condyle of the tibia
The base of the fifth metatarsal has a large, lateral enlargement that gives for muscle mass attachments. This expanded foundation on the fifth metatarsal could be felt like a bony bump with the midpoint together the lateral border of your foot. The expanded distal close of each metatarsal is the head from the metatarsal bone. Each and every metatarsal bone articulates Together with the proximal phalanx of the toe to kind a metatarsophalangeal joint. The heads from the metatarsal bones also rest on the ground and type the ball (anterior finish) from the foot.
clean, articulating surface that varieties the distal and posterior sides from the medial enlargement from the distal femur
Patellofemoral syndrome may very well be initiated by a number of brings about, which include unique variations in the shape and movement from the patella, a direct blow for the patella, or flat ft or inappropriate sneakers that bring about too much turning in or out of the feet or leg.
Just click here like the higher limb, the lower limb is divided into a few areas. The thigh is the fact that percentage of the lower limb Positioned in between the hip joint and knee joint. The leg is precisely the area between the knee joint plus the ankle joint. Distal for the ankle is the foot. The lower limb has 30 bones. These are the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges. The femur is The only bone of the thigh.
