Altman's Clinical Criteria for Hip OA

sen=0.86, spec 0.75

How I remember this:
1. Hip OA has 5 letters, so there are 5 criteria
2. Typically, your hips come in a pair (I'm adding an S to get all 5 criteria in)

P: PAIN, in the hip
A: AGE > 50 y/o
*IR: < 15 degrees, and PAIN with IR
S: stiffness in the morning up to 60 minutes

*there are two criteria

CPR for hip OA

How I remember it:
1. Hip OA has 5 letters, so there are 5 criteria.
2. Firefighters give CPR and put out FIRESS, if you have OA you probably feel like like your hip is on fire!

F: flexion, lateral hip pain with active flexion
IR: IR less than or equal to 25 degrees
E: extension, hip pain with active extension
S: squat, self-reporting squat is aggravating
S: Scour test, with ADD causes groin or lateral hip pain

3/5 criteria present= 68% probability
4/5 present= 91% probability
