Study Notes
Structures with Distinctive Ultrasound Features
- Palmar Margin Indistinct on Ultrasound: The Superficial Digital Flexor Tendon (SDFT) exhibits an indistinct palmar margin on ultrasound.
- SDFT Thinning and Angling: The Proximal Interphalangeal Joint (PIPJ) region is where the SDFT thins and angles to join with the Deep Digital Flexor Tendon (DDFT) distally.
- Decreased Echogenicity: The DDFT demonstrates regions of decreased echogenicity on ultrasound.
- Abnormal Fiber Pattern: In the areas of decreased echogenicity in the DDFT, an abnormal fiber pattern is observed on ultrasound.
- Intersesamoidean Ligament Imaging: The Transverse view is used for imaging the Intersesamoidean ligament.
