USG finding of De Quervain tenosynovitis not uploaded here.

Groove-like Lister's tubercle containing 3rd compartment tendon (extensor pollicis longus).

Case Discussion

Lister's tubercle is the most important bony landmark at the distal end of the radius when examining extensor tendons at the wrist.

When it has a true tubercle-like shape, it separates the 2nd and 3rd compartment tendons.

A variation in Lister's tubercle is noted in above image. It is groove-like, and the 3rd compartment tendon (extensor pollicis longus)  is noted within this groove.
