CME OnDemand: Novel Imaging and MIS Techniques in Foot and Ankle Care (2026)-Module 4: Ultrasound imaging

Video Transcription

Video Summary

This lecture reviews ultrasound imaging of the foot and ankle, covering indications, basic physics, and common clinical applications. Ultrasound is used for evaluating superficial tendon and ligament injuries, plantar fascia disorders, peripheral nerves, soft-tissue masses, foreign bodies, and for guiding injections or aspirations. Grayscale (B-mode) imaging uses high-frequency linear transducers (typically 10–15 MHz) to create real-time, dynamic images based on tissue echogenicity. Key tendon findings include tendinosis, tenosynovitis, and tears; anisotropy is an important artifact. Ligament tears are graded by fiber disruption and dynamic integrity. Elastography can assess tissue stiffness. Limitations include operator dependence and reduced visualization of deeper structures.
