Orthopaedic Surgeon Case Studies

Patient History:

27-year-old male with fractured pelvis from auto impact.

Procedure:

During screw placement procedures, a surgeon may utilize two C-arms or a single C-arm that is positioned from inlet to outlet views to visualize the entry point location. This particular type of screw is placed in a deep area of the pelvis that is difficult to access.

The O-ARM® System was positioned around the patient to acquire a 3D image data set of the anatomy with the patient in the surgical position. The 3D image data set was instantly transferred to the StealthStation® System for instrument navigation. The StealthStation® System allowed the surgeon to visualize the anterior column of the ilium and the surgical instruments from the skin level down through the complete trajectory of screw placement. This visualization may reduce the chance of a misplaced screw - potentially improving accuracy, surgeon confidence, and patient outcomes. The ability to utilize the O-ARM® System to confirm placement of the screws intra-operatively is of tremendous value to the patient, the hospital, and surgeon by potentially avoiding the need for revision surgeries.

“The O-ARM® System makes difficult procedures easier.”
