Dr. Amir Matityahu, Director of Pelvic and Acetabular Trauma and Reconstruction at San Francisco General Hospital will be seen in a story on surgery to repair a fractured pelvis on Tuesday, July 12th on KGO Ch. 7 News at 6:00 p.m..

KGO 7 News features Dr. Amir Matityahu and his patient Jenna who recently benefited from new surgical approaches and imaging technology used in treating accident injuries. The story is scheduled for broadcast on Tuesday, Jul12th on the 6:00 p.m. news. Jenna Quarnes is a 24 year-old labor & delivery nurse who crashed her bike after her wheel caught in a MUNI rail line, sustaining multiple pelvic injuries.

Jenna, who had the accident only three days after starting her new job at San Francisco General Hospital, had her surgery on April 22nd and is now recovering. She's now working at a desk job at the hospital until she's healed enough to resume her duties in labor & delivery.

Dr. Matityahu says that Jenna's procedure took less time to complete than was previously required for such a complex injury and was performed with minimally invasive techniques, thanks in part to new generation imaging technology. "These factors can make the procedure less traumatic for the patient and allow faster healing times in many cases," he says.

"We have been working on advancing the software for the development of the computer assisted navigation of pelvis fractures," says Dr. Matityahu. "In this case, we were able to use this equipment to first create a virtual space that is represented on the computer screen. We are then able to move instruments and implants within that virtual space to allow very precise insertion of implants into corridors of bone that are barely able to accommodate these implants. Moreover, this can be done in 2D or 3D imaging."

"2D is taking several images using the fluoroscopic equipment and storing them in the computer," say Dr. Matityahu. After the computer recognizes the equipment, I am able to move the equipment virtually within the captured images and actually relative to the patient without having to re-take the images again and again every few seconds to see where the equipment is located relative to the images."

"3D is creating an intra-operative CT scan and storing it in the computer'" says Dr. Matityahu. "The navigation equipment registers the images, implants, and tools that we will use to place the hardware. After the computer recognizes the equipment, I am able to move the equipment virtually within several different cross-sectional CT images and also relative to the patient without having to re-take the images again. This technique actually lets me see where the trajectory of my implants is with in the bone allowing intra-operatively planning as I go,” says Dr. Matityahu.
