Orthofix has obtained FDA approval for the Cervical-Stim: 505, the first and only approved device to enhance cervical vertebral fusion. You are being quizzed on important material relative to the clinical trial for the Cervical-Stim, as this data is going to be of great importance as you talk to your surgeons about the success of Cervical-Stim in high-risk patients.  This quiz is a refresher from the training that many of you received in November 2004. You will be receiving all the appropriate literature and materials, and a full-fledged course for the OvA will also be developed very soon. Use this refresher quiz as an opportunity to begin committing this data to memory, as you will use it frequently in selling Cervical-Stim to your targeted surgeons!
