Case contributed by Dr Bruno Di Muzio

Presentation

Cut to 2nd PIP palmar aspect 7 days ago, now cannot flex. FDP tendon tear?

Patient Data

Age: 25-year-old
Gender: Male
Ultrasound

Index finger ultrasound

There is a partial tear involving more than 50% of the distal portion of flexor digitorum profundus tendon, about 5 mm distal to the proximal interphalangeal joint. The tear extends for about 6.8 mm and a small amount of fluid and hypoechogenic material is seen with the tear region. Conclusion: Sonographic features of partial tear (>50%) of the flexor digitorum profundus tendon above the proximal interphalangeal joint.

Annotated image

Annotated images demonstrating both the flexor digitorum superficialis (blue lines) and profundus (yellow line) assessed on a longitudinal view; note the partial tear area extending between the callipers "A". Transverse view delineates the area with probably intact remaining fibres of the flexor profundus tendon (dashed circle); this is best appreciated on the dynamic views scrolling up and down the original study images, where you can see the normal tendon before and after the tear.
