Figure 1. Femur and Patella. The femur is The one bone of your thigh region. It articulates superiorly With all the hip bone in the hip joint, and inferiorly While using the tibia in the knee joint. The patella only articulates Along with the distal close from the femur.

The sensory and motor innervation into the lower limb is provided from the lumbosacral plexus, which is shaped from the ventral rami of your lumbar and sacral spinal nerves with further contributions in the subcostal nerve (T12) and coccygeal nerve (Co1).

The lower limb is divided into 3 areas. They are the thigh, Situated involving the hip and knee joints; the leg, Found among the knee and ankle joints; and distal to the ankle, the foot.

For functional explanations the lower limb is subdivided into relatively arbitrary areas:[forty four] The locations of the hip are all located in the thigh: anteriorly, the subinguinal area is bounded via the inguinal ligament, the sartorius, and also the pectineus and kinds Element of the femoral triangle which extends distally to the adductor longus. Posteriorly, the gluteal region corresponds for the gluteus maximus. The anterior area with the thigh extends distally within the femoral triangle to the region from the knee and laterally on the tensor fasciae latae.

The proximal tibia consists of the expanded medial and lateral condyles, which articulate Together with the medial and lateral condyles of the femur to kind the knee joint. Concerning the tibial condyles may be the intercondylar eminence. Over the anterior side on the proximal tibia is definitely the tibial tuberosity, which happens to be ongoing inferiorly Using the anterior border from the tibia.

The patella (kneecap) is most significant sesamoid bone of the human body (see Figure (PageIndex one )). A sesamoid bone is actually a bone that is certainly incorporated into your tendon of the muscle where by that tendon crosses a joint. The sesamoid bone articulates Together with the underlying bones to circumvent damage to the muscle mass tendon due to rubbing towards the bones through actions from the joint. The patella is located in the tendon from the quadriceps femoris muscle mass, the large muscle mass of the anterior thigh that passes over the anterior knee to attach to your tibia.

The epicondyles present attachment for muscles and supporting ligaments of your knee. The adductor tubercle is a small bump Situated for the top-quality margin from the medial epicondyle. Posteriorly, the medial and lateral condyles are separated by a deep melancholy known as the intercondylar fossa. Anteriorly, The graceful surfaces of your condyles sign up for with each other to form a broad groove known as the patellar floor, which gives for articulation With all the patella bone. The combination in the medial and lateral condyles Together with the patellar floor offers the distal conclusion of your femur a horseshoe (U) condition.

The narrowed location beneath The top is definitely the neck from the femur. It is a popular region for fractures on the femur. The increased trochanter is the big, upward, bony projection Found over the base in the neck. Several muscles that act throughout the hip joint attach towards the greater trochanter, which, due to its projection in the femur, gives additional leverage to here those muscles. The larger trochanter is often felt just below the skin on the lateral facet of your respective upper thigh.

The hip joint has a solid capsule that features almost all of the femoral neck. The capsule is further more strengthened by pretty potent ligaments anteriorly, and by smaller half rotator cuff muscles posteriorly. ThFe iliofemoral ligament is the strongest in the human body; it is actually Y-formed, passing over the front in the joint (Figure eight.

The femur is The only bone from the thigh. Its rounded head articulates with the acetabulum with the hip bone to kind the hip joint. The head has the fovea capitis for attachment of your ligament of The pinnacle in the femur. The narrow neck joins inferiorly Along with the better and lesser trochanters. Passing in between these bony expansions are definitely the intertrochanteric line to the anterior femur as well as the larger intertrochanteric crest to the posterior femur.

The fibula is the slender bone located within the lateral aspect in the leg (see [url]). The fibula won't bear pounds. It serves generally for muscle mass attachments and so is basically surrounded by muscles. Only the proximal and distal ends of your fibula is often palpated.

Treatment normally entails halting the activity that makes knee discomfort for just a time frame, accompanied by a gradual resumption of activity. Good strengthening in the quadriceps femoris muscle mass to appropriate for imbalances is usually essential to help avert reoccurrence.

lateral, expanded region of the proximal tibia that features The graceful surface area that articulates with the lateral condyle of your femur as Section of the knee joint

The pelvis sorts the url between the vertebral column along with the thigh for the transmission of your body weight downwards through the trunk to the hip and knee joints, and on on the toes.
