ABSTRACT
Injuries to the flexor pulley system of the hand, while uncommon, can be problematic and debilitating for patients. Current standards of diagnosis for A2 pulley disruptions often include costly imaging studies and inaccurate clinical testing. We present the case of a patient with an isolated complete A2 pulley avulsion that was diagnosed by employing a simple technique using a silicone wedding ring. A silicone wedding band was applied over the region of a suspected A2 pulley rupture, resulting in the immediate restoration of full range of motion as well as complete resolution of the injury after three months, without any need for surgical intervention. The usage of this ring confirmed an A2 pulley avulsion that was visualized on magnetic resonance imaging (MRI). The proposed "Wedding Band Test" is potentially an accurate and inexpensive diagnostic tool for clinical evaluation of A2 pulley ruptures.
