Abstract
An instrument for controlled delivery of a device to a target area near a defect of a bone is provided. The instrument comprises a guide frame having a plurality of device portals, each portal defining a trajectory. The guide frame further includes visual markers for aligning the guide frame to an anatomical landmark on the bone to be treated. The instrument also includes a holder for releasable attachment with the guide frame. Each device portal is configured to provide accurate and controlled delivery of the device to the target area. In one example, the markers are radiopaque, and are visualized through fluoroscopy. A method of using the instrument is also provided.
