Orthopedics This Week reported on a recent study comparing the effectiveness of the HipAlign navigation system to traditional methods of acetabular cup placement. The study, co-authored by HSS hip & knee surgeon Edwin P. Su, MD, investigated the use of a handheld navigation system by a single surgeon during total hip replacements. Statistics such as the guiding cup position and removal of pins were recorded during the study.

Dr. Su told OTW, "I've had experience with using [HipAlign's] technology in total knee replacements and found it to enhance my results. I've been helping them develop the application for use in the anterior total hip, to provide the same kind of intraoperative information that can help surgeons perform this type of surgery."

"The most interesting results were that a significantly greater percentage of acetabular components were positioned in a target zone, as opposed to those THA performed conventionally. This means greater precision in implant placement, while at the same time reducing the risks of radiation to the surgeon, operative staff, and patient. I believe that this technology can help surgeons who perform this type of operation with intraoperative information to achieve their surgical plan, while reducing the exposure to fluoroscopy," added Dr. Su.
