Choice of modality
| Age | Scenario | Usual appropriate initial imaging |
|---|---|---|
| <4 weeks | Equivocal physical examination or risk factors | No imaging |
| Physical findings of DDH | Ultrasonography | |
| 4 weeks - 4 months | Equivocal physical examination or risk factors | Ultrasonography |
| 4 - 6 months | Concern for DDH | X-ray. Ultrasonography may be appropriate[notes 2] |
| >6 months | X-ray |
Hip dysplasia diagnosed by ultrasound[2] or projectional radiography (see X-ray of hip dysplasia.[3] Ultrasound imaging is generally preferred at up to 4 months due to limited ossification of the skeleton.[1][notes 2]
- Projectional radiography
- Main article: X-ray of hip dysplasia
Despite the widespread of ultrasound, pelvis X-ray is still frequently used to diagnose and/or monitor hip dysplasia or for assessing other congenital conditions or bone tumors.[4]
The most useful lines and angles that can be drawn in the pediatric pelvis assessing hip dysplasia are as follows:[4]
Different measurements are used in adults.[4]==Notes==
