This article presents a case of a dorsal trigger wrist, which was brought on by a rupture of the fibro-osseous septum of the second extensor compartment. This situation is highly uncommon and has not been previously documented. The septum, which divides the extensor carpi radialis brevis and the extensor carpi radialis longus on the second extensor compartment, is present in almost 45% of the population. The patient underwent surgical reconstruction of the septum, and a complete resolution of symptoms was achieved.
