The talk details how to assess various types of acetabular fracture. Combination of X-rays, CT Scan and 3D reconstruction and 3D printing also known as 3DGraphy. Basic 8 patterns and importance of various radiological parameter are explained.

14. Roof Arc Angle

15. Roof Arc angle

17. Roof Arc Angle
The angle formed between a vertical tangent
through femoral head and a vertical line though
the fracture.
It helps determine the fracture pattern stability
if the fracture line exits outside the weight
bearing dome of the acetabulum it is considered
a stable fracture.

18. Gull Sign
▪ represents impaction of superomedial roof
▪ seen on iliac oblique view
▪ pathognomic for posterior wall fractures

19. Spur Sign
Represents most caudal part of intact ilium
due to medialization of articular components
Seen on obturator view
Pathogonomic of ABC #

21. Classification

24. CT SCAN
Look at the orientation of fracture line
Look at position or quadrant of fracture
look at the level of the fracture

25. Orientation
Oblique Horizontal Verticaal
Combination

26. Oblique # Line:ant wall ,post wall
Horizontal # Line: Anterior, Posterior or both column
Vertical: Transverse; T shaped
Horizontal & Oblique: Posterior Wall + Column
