What does the PA axial view of the knee best demonstrate?

What does the PA axial view of the knee best demonstrate?

Knee PA Axial Holmblad Method Purpose and Structures Shown This projection best demonstrates the intercondylar fossa of the femur, femoral condyles, tibial plateaus, and intercondylar eminence. It is useful in evaluating for bony or cartilaginous pathology and narrowing of the joint space.

How much should the knee be flexed for a lateral view?

For a lateral view, the patient is positioned on the affected side, with the knee flexed 20-30 degrees. One method to obtain the tunnel view is to have the knee flexed 40-50 degrees with the patient prone and support placed under the tibia-fibula.

What is a notch view of knee?

The Béclere method intercondylar view is an additional projection of the knee, used to better examine the tibial plateau and femoral intercondylar spaces. It is anecdotally known as a ‘notch view’.

What is a sunrise view of the knee?

Another view of the knee is obtained. View sunrise view. This is called the sunrise view because the patella appears to be rising over the horizon. This view is taken with the knee flexed. The radiograph is taken with the x-ray beam tangential to the patella parallel to the long axis of the lower extremity.

How do I get perfect lateral knees?

Place index finger against medial border of patella, and press it laterally. Rest knee on its anteromedial side to hold patella in a position of lateral displacement. Central ray Directed to joint space between patella and femoral condyles at an angle of 25- 30 degrees caudad.

How can you tell if the lateral knee is over rotated or under rotated?

To summarize, if the medial adductor tubercle free from superimposition, rotate the knee externally. If the lateral condyle significantly superimposes the medial adductor tubercle, the knee must be internally rotated.

What position requires a caudal Cr angle of 30 degrees from horizontal?

With 45 degrees knee flexion, angle the CR 30 degrees caudal from the horizontal plane (60 degrees from the vertical) to achieve a 30 degrees CR-to-femur angle. CR enters midway between patellae at the level of the patellofemoral joint.

What is a sunrise view?

View sunrise view. This is called the sunrise view because the patella appears to be rising over the horizon. This view is taken with the knee flexed. The radiograph is taken with the x-ray beam tangential to the patella parallel to the long axis of the lower extremity.

What does intercondylar mean?

Medical Definition of intercondylar : situated between two condyles the intercondylar eminence of the tibia the intercondylar fossa or notch separates the condyles of the femur.

Where is the notch in the knee?

The intercondylar notch is the open space that lies between the medial and lateral femoral condyles of the distal femur and houses the substance of both the anterior and posterior cruciate ligaments.
