Other Causes of Limping
- Developmental dysplasia
- Fracture
- Toddler's fracture
- Tillaux fracture, adolescent
- Neoplasm:
- Leukemia
- Ewings
- Osteogenic sarcoma
- Metastatic neuroblastoma
- Osteomyelitis

- Other:
Evaluation
- X-ray hip, knee
- Consider CBC, ESR, total CK
- Consider hip ultrasound (vs CT)
Kocher Criteria for septic arthritis of the hip
- ESR > 40 mm/hr
- WBC > 12,000/microliter
- Refusal or inability to weight bear on affected joint
- Fever 38.5° C or greater
| Number of Kocher Criteria | Chance of Septic Joint |
| 1 | 3% |
| 2 | 40% |
| 3 | 93% |
| 4 | 99% |
