lipohemarthrosis by ultrasound

23 May

JEM article covers the basics, with some nice visual aids:

WHY DO I CARE?

lipohemarthrosis suggests intraarticular fracture

sometimes hard to see on X-ray (can miss up to 21% of fx’s)

also, what if X-ray’s are down/unavailable?

 

WHERE TO PUT THE ULTRASOUND:

suprapatellar bursa

 

WHICH PROBE?

linear transducer (we’re not looking too deep here)

 

WHAT TO LOOK FOR:

a = fat (anechoic spheres of fat help identify this layer)

b = serum

c = blood cells

probably is better seen the more time has passed after trauma (takes time to layer out)
