The stability of your pelvis is furnished by potent ligaments binding the innominate bone to the sacrum anteriorly and posteriorly. The bony pelvis gives a foundation with the attachment of muscles of the trunk and the hip.

The fibula could be the slender bone located around the lateral side in the leg (see Figure (PageIndex 3 )). The fibula will not bear bodyweight. It serves largely for muscle mass attachments and therefore is basically surrounded by muscles. Only the proximal and distal ends in the fibula could be palpated.

The extensor hallucis longus has its origin over the fibula and the interosseus membrane involving the two other extensors and is, equally towards the extensor digitorum, is inserted on the last phalanx of big toe ("hallux"). The muscle dorsiflexes the hallux, and functions comparable to the tibialis anterior in the load-bearing leg.[29] Two muscles within the lateral aspect in the leg sort the fibular (peroneal) team. The fibularis (peroneus) longus and fibularis (peroneus) brevis both equally have their origins to the fibula, and they both of those move driving the lateral malleolus in which their tendons move beneath the fibular retinacula. Under the foot, the fibularis longus stretches in the lateral to the medial aspect in a groove, So bracing the transverse arch in the foot. The fibularis brevis is hooked up over the lateral facet to your tuberosity from the fifth metatarsal. Alongside one another, both of these fibularis muscles variety the strongest pronators with the foot.[30] The fibularis muscles are highly variable, and several other variants can at times be present.[31]

The nerves on the lumbar plexus pass before the hip joint and predominantly assistance the anterior Element of the thigh.[46]

A. The lower limb is split into 3 regions. The thigh is definitely the location Positioned in between the hip and knee joints. It contains the femur as well as patella. The hip joint is shaped through the articulation in between the acetabulum of your hip bone and The top in the femur. The leg will be the region between the knee and ankle joints, and contains the tibia (medially) and the fibula (laterally). The knee joint is formed via the articulations concerning the medial and lateral condyles of your femur, as well as medial and lateral condyles with the tibia. Also connected to the knee could be the patella, which articulates With all the patellar surface on the distal femur.

In human anatomy, the lower leg is the Portion of the lower limb that lies concerning the knee along with the ankle.[one] Anatomists restrict the phrase leg to this use, as an alternative to to the complete lower limb.

The fovea capitis can be a minimal indentation about the medial side in the femoral head that serves as the website of attachment with the ligament of The pinnacle of your femur. This ligament spans the femur read more and acetabulum, but is weak and provides small support for your hip joint. It does, having said that, have an important artery that provides The top of your femur.

From the deep layer, the tibialis posterior has its origin around the interosseus membrane plus the neighbouring bone places and operates down powering the medial malleolus. Beneath the foot it splits into a thick medial portion hooked up towards the navicular bone and a rather weaker lateral part inserted on the a few cuneiform bones. The muscle generates simultaneous plantar flexion and supination during the non-bodyweight-bearing leg, and approximates the heel to your calf of the leg. The flexor hallucis longus arises distally within the fibula and within the interosseus membrane from the place its somewhat thick muscle mass belly extends considerably distally. Its tendon extends beneath the flexor retinaculum to the only real of your foot And eventually attaches on The bottom of the final phalanx of the hallux.

The femur is The only bone on the thigh. Its rounded head articulates Together with the acetabulum on the hip bone to kind the hip joint. The head has the fovea capitis for attachment from the ligament of the head of your femur. The slender neck joins inferiorly Along with the increased and lesser trochanters. Passing amongst these bony expansions will be the intertrochanteric line within the anterior femur and also the greater intertrochanteric crest within the posterior femur.

The ankle joint is usually a synovial hinge joint. The articular surfaces with the ankle joint are classified as the upper surface of the talus bone of your foot plus the inferior surface area of the tibia. The burden-bearing surfaces are definitely the curved trochlear with the talus along with the reciprocal shallow notch in the tibia.

Pay a visit to This page to accomplish a virtual knee substitute surgical procedures. The prosthetic knee components should be appropriately aligned to operate adequately. How Is that this alignment ensured?

This pathological fracture is particularly witnessed in more mature people today, when osteoporosis has weakened the bone. This fracture can interrupt the primary blood provide to The top on the femur plus the bone may perhaps are unsuccessful to unite (avascular necrosis).

Ordinarily, the big joints of the lower limb are aligned in the straight line, which represents the mechanical longitudinal axis on the leg, the Mikulicz line. This line stretches in the hip joint (or even more specifically The top of your femur), throughout the knee joint (the intercondylar eminence of the tibia), and down to the center of your ankle (the ankle mortise, the fork-like grip among the medial and lateral malleoli). During the tibial shaft, the mechanical and anatomical axes coincide, but inside the femoral shaft they diverge six°, leading to the femorotibial angle of 174° in a leg with usual axial alignment.

The base of your fifth metatarsal has a considerable, lateral growth that provides for muscle mass attachments. click here This expanded base of the fifth metatarsal is usually felt being a bony bump on the midpoint along the lateral border with the foot. The expanded distal stop of each metatarsal is The pinnacle in the metatarsal bone. Each metatarsal bone articulates While using the proximal phalanx of a toe to form a metatarsophalangeal joint. The heads with the metatarsal bones also rest on the bottom and kind the ball (anterior end) with the foot.
