Fluoroscopic Grid Aids Precise Hip Replacement Surgery

The system is designed for use with a 9-inch C-arm when both lesser trochanters are not visible in the field of view, allowing the surgeon to compare two anterior-posterior hip views using the TearDrop Target surgical technique to facilitate intra-operative decisions.

Other features of the system include the BOAFit attachment system, high contrast markings, seamless integration into the standard surgical workflow with no disposables or instrumentation. The system is compatible with all implant and C-arm manufacturers, and has been shown to decrease surgical time by up to fifteen minutes. OrthoGrid also manufactures the Phantom MSK system, which incorporates with existing hospital equipment and is designed for the anterior approach total hip arthroplasty workflow.

“Outpatient total hip replacement procedures are growing rapidly due in large part to the potential for added convenience, reduced costs, and quicker return to home for the patient,” said Edouard Saget, President of OrthoGrid Systems. “Increasingly, our customers have demanded to have a HipGrid that is compatible with 9-Inch C-arm systems commonly found in outpatient surgery centers, and so we are pleased to immediately commence shipments of this compelling new product.”

Fluoroscopy utilizing a mobile C-arm is the most widely used technology for placement and alignment in orthopedics. While fluoroscopy has a positive impact on THA outcomes, image distortion--caused by unseen continuously variable electromagnetic forces (EMF)--can potentially cause surgeons to make incorrect adjustments. The most prevalent type of distortion is S-Distortion, which can cause up to 19 mm in variation from one side of field of view to the other.
