The large enlargement observed about the medial aspect from the distal tibia is the medial malleolus (“little hammer”). This kinds the massive bony bump discovered to the medial side of your ankle area. The two the smooth area on the inside from the medial malleolus and The graceful place within the distal end of your tibia articulate While using the talus bone in the foot as Section of the ankle joint.
The interosseous border of every bone will be the attachment web site with the interosseous membrane on the leg, the connective tissue sheet that unites the tibia and fibula.
easy, articulating floor that sorts the distal and posterior sides of the lateral expansion in the distal femur
sleek, articulating surface area that kinds the distal and posterior sides in the lateral expansion of the distal femur
Medial and lateral rotation transform the femur inwards and outwards. These movements convert the foot inwards and outwards as there's no rotation within the knee.
The leg consists of the big tibia about the medial facet and the slender fibula around the lateral side. The tibia bears the load of your body, While the fibula won't bear pounds.
We have been dedicated to delivering price, high-quality and an outstanding expertise to every customer. By means of our services, we try to get the finest end result for every person.
The consistent shifting of place reduces exhaustion in Anybody muscle mass group, and also aids the return of blood to the guts with the pumping action of leg muscles.
deep melancholy on the posterior facet with the distal femur that separates the medial and lateral condyles
A leg is considered straight when, Using the ft brought together, both the medial malleoli with the ankle along with the medial condyles in the knee are touching. Divergence from the normal femorotibial angle is referred to as genu varum if the center of your knee joint is lateral to your mechanical axis (intermalleolar distance exceeds three cm), and genu valgum if it is medial to the mechanical axis (intercondylar length exceeds 5 cm). These situations impose unbalanced masses to the joints and stretching of possibly the thigh's adductors and abductors.[12]
Look at the illustrations of your tibia, fibula plus the bones in the foot noticed in medial and lateral perspective in Appendix I.
Within the posterior shaft of your femur will be the gluteal tuberosity proximally along with the linea aspera during the mid-shaft location. The expanded distal conclude includes three articulating surfaces: the medial and lateral condyles, and the patellar floor. The outside margins of the condyles tend to be the medial website and lateral epicondyles. The adductor tubercle is over the outstanding facet of the medial epicondyle.
Normally, the massive joints of the lower limb are aligned within a straight line, which signifies the mechanical longitudinal axis with the leg, the Mikulicz line. This line stretches from the hip joint (or more exactly The top with the femur), in the knee joint (the intercondylar eminence from the tibia), and right down to the center on the 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 within the femoral shaft they diverge 6°, leading to the femorotibial angle of 174° in the leg with usual axial alignment.
The anterior fifty percent of your foot is shaped from the 5 metatarsal bones, which are located in between the tarsal bones with the posterior foot as well as the phalanges of the toes (see Figure four). These elongated bones are numbered 1–five, beginning Along with the medial side on the foot. The first metatarsal bone is shorter and thicker in comparison to the Other people. The next metatarsal is the longest. The base with the metatarsal bone will be the proximal conclude of each and every metatarsal bone. These articulate With all the cuboid or cuneiform bones.
