Abstract



Purpose


Many different stress views for the diagnosis of scapholunate (SL) instability have been described in the literature. The purpose of this study is to compare these stress views and determine which view has the greatest utility for demonstrating SL gap radiographically.



Methods


We performed a literature search for articles describing SL radiographic stress views. We created SL instability in 9 cadaveric wrists by ligamentous sectioning and imaged each specimen using all radiographic views found in the literature. These included the “clenched pencil” view, clenched fist views in varying positions, and traction views. Scapholunate gaps were measured using digital calipers.
