The patella is definitely the kneecap and articulates with the distal femur. The tibia could be the much larger, body weight-bearing bone Situated within the medial facet of your leg, along with the fibula is the thin bone with the lateral leg. The bones in the foot are divided into 3 teams. The posterior part of the foot is shaped by a group of 7 bones, Each and every of which is recognized as a tarsal bone, whereas the mid-foot contains 5 elongated bones, Every of which is a metatarsal bone. The toes comprise 14 modest bones, Every single of which is a phalanx bone from the foot.
modest ridge functioning down the lateral side with the tibial shaft; for attachment of the interosseous membrane amongst the tibia and fibula
Observe this online video to view how a fracture on the mid-femur is surgically fixed. How are The 2 portions in the damaged femur stabilized through surgical fix of a fractured femur?
The medial ligament is mostly torn, As well as in critical conditions the anterior cruciate ligament is associated as the tibia rotates laterally. Considerably less normally, the lateral ligament is torn, as well as posterior cruciate ligament tears in the event the tibia is compelled backwards in relation to your femur.
medial, expanded location from the proximal tibia that features the smooth floor that articulates with the medial condyle on the femur as Element of the knee joint
The patella is really a sesamoid bone Positioned inside a muscle mass tendon. It articulates With all the patellar surface over the anterior aspect in the distal femur, thereby preserving the muscle mass tendon from rubbing towards the femur.
In the course of extension with the knee, the quadriceps femoris muscle mass pulls the patella both superiorly and laterally, Using the lateral pull lower limb supports increased in Girls because of their substantial Q-angle. This makes women much more liable to developing patellofemoral syndrome than Guys. Usually, the big lip about the lateral facet of the patellar area of your femur compensates for your lateral pull about the patella, and therefore aids to keep up its suitable monitoring.
The patella articulates Together with the patellar surface area from the femur and thus helps prevent rubbing with the muscle tendon versus the distal femur. The patella also lifts the tendon from the knee joint, which raises the leverage power on the quadriceps femoris muscle since it acts over the knee. The patella doesn't articulate Along with the tibia.
Inside the lower leg, the anterior tibial enters the extensor compartment close to the higher border in the interosseus membrane to descend amongst the tibialis anterior as well as the extensor hallucis longus. Distal for the superior and extensor retinacula of your foot it gets the dorsal artery from the foot.
Functionally, the muscles from the leg are both extensors, to blame for the dorsiflexion of the foot, or flexors, liable for the plantar flexion. These muscles might also classified by innervation, muscles provided via the anterior subdivision from the plexus and people equipped from the posterior read more subdivision.[27] The leg muscles performing over the foot are called the extrinsic foot muscles while the foot muscles situated in the foot are known as intrinsic.[28]
Stop by This website to complete a Digital knee alternative surgical treatment. The prosthetic knee parts need to be thoroughly aligned to operate thoroughly. How Is that this alignment ensured?
These more info bones would be the medial cuneiform, the intermediate cuneiform, as well as the lateral cuneiform. Each and every of these bones contains a broad exceptional area as well as a narrow inferior area, which collectively produce the transverse (medial-lateral) curvature with the foot. The navicular and lateral cuneiform bones also articulate with the medial side in the cuboid bone.
With the anterior thigh muscles the most important are definitely the 4 muscles of your quadriceps femoris: the central rectus femoris, which happens to be surrounded by the a few vasti, the vastus intermedius, medialis, and lateralis. Rectus femoris is hooked up into the pelvis with two tendons, though the vasti are inserted into the femur. All 4 muscles unite in a typical tendon inserted in the patella from the place the patellar ligament extends it right down to the tibial tuberosity. Fibers through the medial and lateral vasti kind two retinacula that stretch past the patella on either sides all the way down to the condyles with the tibia.
