This is the third in a series of papers related to procedure-oriented joint anatomy. This article reviews the anatomy of the wrist and hand and its relationship to procedures in the clinical setting with or without ultrasound/electromyography (EMG) guidance. Anatomically correct axial and coronal schematics allow injections to be envisioned relative to clinically important anatomy for common wrist and finger procedures. Cross-sectional schematics for the wrist and hand were drawn as they appear in imaging projections. The levels and planes of cross section were selected to highlight important anatomic landmarks for injection. It is hoped that these schematics allow for safer and more accurate needle procedures in the wrist and hand area.
