Best view for lipohemarthrosis:
A) Lateral
B) AP
A) Lateral
Answer: A
Notes:
- Lipohemarthrosis results from an intra-articular fracture with escape of fat and blood from the
bone marrow into the joint, and is most frequently seen in the knee, associated with a tibial
plateau fracture or distal femoral fracture, rarely a patellar fracture.
Pediatric patient with foreign body, what to do:
A) AP
B) PA
C) Lateral
D) Bilateral decubitus
D) Bilateral decubitus
Answer: D
Notes:
- Bilateral lateral decubitus (can be done to increase sensitivity).
- Bilateral decubitus views should demonstrate hyperinflation of the affected lung on both
radiographs; in the obstructive foreign body there will be air-trapping and therefore
hyperlucency of the dependent lung.
Regarding lines:
