Reports come from manufacturers, hospitals and patients and are not verified by the FDA. A report does not prove the device caused the event. Widely used products collect more reports, so totals can't be used to compare products or estimate failure rates. Only reports that name a model's exact device identifier are counted.

   Torque screw may crack or separate. If used, an affected screw could lead to inadequate head stabilization, compromised surgical precision, procedural delays, requirement for alternate head fixation methods, and risk of patient injury.

2. Feb 17, 2022Terminated

   Reports have been received that after normal or routine lateral forces are applied to the head fixation device, the split block clamp may deflect (rotationally around the axis) and not return to within acceptable distance from its prior position after the force is removed. In order to reduce deflection at the table mount location, users have tightened the hand knob screw to a degree that it is then difficult to untighten it later in the clinical workflow. Rotational movement at the table attachment point could result in HFD movement going unnoticed, which could result in a situation where surgical or medical intervention is necessary, a situation where navigation needs to be reestablished, or a situation resulting in extended time under anesthesia for the patient. It may also be difficult to loosen the mount clamp component after use, potentially leading to ergonomic injury or a workaround during equipment teardown.
