Axial computed tomography of pilon fractures

How do you do a CT scan of the foot?

During the procedure, you will lie very still on a table.
This table passes your foot and ankle through the x-ray machine, which is shaped like a doughnut with a large hole.
The machine, which is linked to a computer, rotates around the patient, taking pictures of one thin slice of tissue after another..

What does a CT scan show on ankle?

The main role of foot and ankle CT in preoperative surgical planning involves the assessment of deformities in adults, assessment of peri-articular or intra-articular fractures, periprosthetic fractures, prosthesis loosening, and bony collapse from avascular necrosis..

What is CT scan for fracture?

A CT scan of the bones may be performed to assess bones, soft tissues, and joints for damage, lesions, fractures, or other abnormalities, particularly when another type of examination, such as X-rays or physical examination are not conclusive..

What is the AO classification of a pilon fracture?

[4][7][8][9][10][11][12][13][14] In the AO/OTA classification for long bone fractures, pilon fractures are classified as extra-articular (4.

1. A), partial articular (4
2. B), and intra-articular (4
3. C), and further subclassified based on the degree of comminution

What is the AO OTA classification of a pilon fracture?

What is the approach for a pilon fracture?

Most tibial pilon fractures are best approached anteriorly, either anteromedially or anterolaterally.
The size of the anterolateral fragment helps determine the optimal approach.
When it is large, and its medial fracture plane is at or near the medial malleolus, an anteromedial approach is recommended..

What is the mechanism of pilon fracture?

Pilon fractures occur when the talus is driven into the tibial plafond.
The forces that cause fracture fragments in the distal tibial metaphysis, articular and soft-tissue damage, can be vertical, rotational, angular, or a combination of these..

What is the use of CT scan for fracture?

What are the reasons for a CT scan of the bones? A CT scan of the bones may be performed to assess bones, soft tissues, and joints for damage, lesions, fractures, or other abnormalities, particularly when another type of examination, such as X-rays or physical examination are not conclusive..

1. C).
Again, the variability and personality of these fragments is dictated by the position of the foot and load applied, bone quality, and presence of arthritis.

1. A), partial articular (4
2. B), and intra-articular (4
3. C), and further subclassified based on the degree of comminution
