Perfectly

What is the Mortise?

3 sided opening of the anke joint

What 3 parts makes up the Tibia?

Proximal extremity, distal extremity and central body

What is included in the proximal extremity of the Tibia?

Medial and lateral condyles Intercondyloid Eminence Articular facets (tibial plateau) Tibial Tuberosity

What is the Intercondyloid Eminence?

Superior surface of the tibial head made into 2 parts - medial and lateral intercondylar tubercles

What is the Tibial Plateau?

2 facets that articulate with the femur. The plateau slopes about 10-20 degrees

Where is the Tibial Tuberosity located?

Anterior portion of the proximal extremity, but distal to the condyles

What is the ridge of the Tibia body?

Called the crest and is referred to as the shin

What makes up the distal extremity of the Tibia?

Medial Malleolus Fibular notch

What is the fibular notch?

On the distal end of the Tibia, where the distal end of the fibula fits

How is the Fibula located to the Tibia?

Lateral and posterior

What makes up the proximal portion of the fibula?

Apex, head and neck

What is the longest bone in the body?

Femur

What is the largest Sesamoid bone in the body?

Patella

Where is the patella located?

Above the knee joint

What is the intercondylar fossa?

Notch very deep on the posterior aspect of the femur, between the condyles

Which condyle of the femur extends more distally?

Medial condyle

is the angle of the femur greated on a woman or man? Why?

Woman - broadness of hips and they are usually shorter

What is the adducter tubercle?

Raised area that receives a tendon on the medial side of the femur above the condyle

What are the medial and lateral epicondyles of the femur?

Rough prominences on the outermost tips of the medial and lateral condyles

What does the condyles of the femur articulate with?

Tibia

What is the patellar surface?

Surface of the femur located directly posterior to the patella - it's also known as the trochlear groove/intercondylar surface

What is the knee joint proper?

Femorotibial joint Patellofemoral joint

What lower limb joints are synovial?

All except distal tibiofibular - which is fibrous joint

What lower limb joints are ginglymus?

Interphalangeal joints

What lower limb joints are Ellipsoidal?

Metatarsalphalangeal joints

What lower limb joints are plane/gliding?

Tarsometatarsal Intertarsal Proximal Tibiofibular joint

What lower limb joints are saddle?

Ankle Patellofemoral

What lower limb joints are bicondylar?

Femorotibial

kVp for lower limb?

60-80

What is plantar surface?

Bottom of the foot (posterior)

What is dorsum surface?

Top of the foot (anterior)

What is dorsiflexion?

Bring toes back towards the head

What is plantarflexion?

Points towards downward

What is inversion?

Rolled the ankle inward (varus)

What is eversion?

Rolled the ankle outward (valgus)

If the adductor tubercle can be seen on a lateral knee xray - is the knee over or under rotated?

Under rotated
