joint Situated in the proximal end of your lower limb; fashioned because of the articulation amongst the acetabulum in the hip bone and the head of your femur
Dorsiflexion is if the foot is drawn upwards in the direction of the leg (Determine 8.4). Dorsiflexion from the ankle lifts the toes away from the ground in the event the leg is swinging forwards in walking or kicking a ball.
The distal conclusion on the femur has medial and lateral bony expansions. Around the lateral facet, The sleek portion that handles the distal and posterior facets of the lateral expansion is definitely the lateral condyle on the femur. The roughened location on the outer, lateral aspect from the condyle is definitely the lateral epicondyle on the femur. Similarly, The graceful area of the distal and posterior medial femur could be the medial condyle in the femur, and the irregular outer, medial aspect of Here is the medial epicondyle on the femur. The lateral and medial condyles articulate With all the tibia to variety the knee joint.
View this online video to check out how a fracture with the mid-femur is surgically fixed. How are the two portions in the broken femur stabilized through surgical repair of a fractured femur?
Take a look at This website to conduct a virtual knee substitution medical procedures. The prosthetic knee components has to be appropriately aligned to operate thoroughly. How Is that this alignment ensured?
The proximal finish in the tibia is tremendously expanded. The two sides of this expansion kind the medial condyle of your tibia and the lateral condyle in the tibia. The tibia doesn't have epicondyles. The best surface area of each condyle is clean and flattened.
irregular elevation to the outstanding conclusion of the tibia, among the articulating surfaces with the medial and lateral condyles
The elongated shaft from the femur has a slight anterior bowing or curvature. At its proximal end, the posterior shaft has the gluteal tuberosity, a roughened area extending inferiorly from the bigger trochanter.
The acetabulum lies in the facet on the pelvis and it is a deep, outwards-struggling with cup surrounded by a rim of fibrocartilage, often known as a labrum. The head of your femur varieties the ball, that is two-thirds of the sphere. Once the ball is in the socket, the labrum curves inwards further than the equator of The top from the femur to grip it and assistance to hold it set up.
Inside the lower leg, the anterior tibial enters the extensor compartment close to the higher border with the interosseus membrane to descend amongst the tibialis anterior as well as the extensor hallucis longus. Distal to the top-quality and extensor retinacula on the foot it becomes the dorsal artery with the foot.
The head in the fibula would be the compact, knob-like, proximal end from the fibula. It articulates Together with the inferior aspect of the lateral tibial condyle, forming the proximal tibiofibular joint. The thin more info shaft in the fibula has the interosseous border on the fibula, a slim ridge jogging down its medial side for that attachment of your interosseous membrane that spans the fibula and tibia.
If stretching with the ligaments is extended, excessive, or repeated, it can lead to a gradual lengthening on the supporting ligaments, with subsequent despair or collapse of your longitudinal arches, especially over the medial side on the foot. This affliction is referred to as pes planus (“flat foot” or “fallen arches”).
Patellofemoral syndrome may very well website be initiated by many different brings about, together with individual variations in the shape and movement on the patella, a immediate blow into the patella, or flat toes or poor sneakers that induce too much turning more info in or out with the toes or leg.
Stabilising surfaces will be the medial malleolus of the tibia plus the lateral malleolus in the fibula, which give a agency grip on the sides with the talus, creating a bony mortice and tenon joint.
