Spectrum of normal and pathologic findings in the region of the first extensor compartment of the wrist: sonographic findings and correlations with dissections.

OBJECTIVE: The purpose of this presentation is to review pathologic conditions that lead to pain at the radial aspect of the distal radius and to address anatomic variations of the first extensor compartment that exist and may have diagnostic and therapeutic implications.

METHODS: Our presentation is based on a review of cases from teaching files and observations made in anatomic specimens.

RESULTS: The discussed conditions include de Quervain tenosynovitis, intersection syndrome, and Wartenberg syndrome. Sonographic diagnosis of these conditions is addressed, and correlations are provided with anatomic specimens.

CONCLUSIONS: Sonography is able to depict and differentiate between these conditions.
