Purpose: To identify patients likely to be presenting with hip osteoarthritis.
Stage of CPR Development: Derivation.
Rule:

2. (+) Scour Test for groin or lateral hip pain
3. Active hip flexion causing lateral hip pain
4. Passve internal rotation < 25 degrees
5. Active hip extension causing hip pain
Interpretation:
| Variables | Sensitivity | Specificity | +LR | -LR | Post-Test Prob |
| 1 | 0.95 | 0.18 | 1.20 | 0.27 | 33.0% |
| 2 | 0.81 | 0.61 | 2.10 | 0.31 | 46.0% |
| 3 | 0.71 | 0.86 | 5.20 | 0.33 | 68.0% |
| 4 | 0.48 | 0.98 | 24.30 | 0.53 | 91.0% |
| 5 | 0.14 | 0.98 | 7.30 | 0.87 | 75.0% |
