Summary
Ultrasound is an accurate method of guiding injections into the foot and ankle.
Researchers evaluated the accuracy of ultrasound-guided injections for common injection sites in the foot and ankle. They found that ultrasound guidance was 100% accurate for injections into the first and second metatarsophalangeal (MTP) joints, the tibiotalar joint, the Achilles peri tendinous space, the flexor hallucis longus (FHL) sheath, and the posterior tibial tendon (PTT) sheath. Ultrasound guidance was 90% accurate for injections into the subtalar joint.
These findings suggest that ultrasound is a highly accurate method of localizing injections into a variety of locations in the foot and ankle. This may be an advantage over blind injection and fluoroscopic injection techniques, which do not provide real-time visualization of the injection site.
