After making a mistake earlier today, I thought it’d be a good time to review some basics.
Before we begin – is this a male or female pelvis?
Read on if you don’t know!
How do you tell the difference between a male and female pelvic bone on an x-ray?
Here are two patients.
Here are some ways to tell the difference
#1: Look at the public arch
In males this angle is sharp. In females it looks wider.
#2: Look at the pelvic inlet
In males the appearance is ‘heart shaped’. In females it is round
#3 Most easy way: Look at the soft tissue
In males you see a penis. Aha! In females… you don’t.
So, with this in mind? Is the x-ray patient male or female?
The answer is… male
