Overview
Ultrasound-guided injection uses real-time imaging to precisely deliver medication to target structures.
Advantages
- Accuracy — visualize needle tip in real-time
- Safety — avoid nerves and blood vessels
- Efficacy — confirm medication delivery to target
Common Targets
| Joint/Structure | Approach | Medication |
|---|---|---|
| Shoulder | Posterior | Corticosteroid |
| Knee | Suprapatellar | Hyaluronic acid |
| Hip | Anterior | PRP |
Ultrasound guidance improves injection accuracy to >95% compared to landmark-guided approaches.
Procedure
- Position patient and apply gel
- Identify target with ultrasound
- Insert needle under visualization
- Confirm placement and inject
