Evolution of Technology

Intraoperative Navigation

Much research and development has been performed regarding the utilization of existing and new technology for hip arthroscopy. Intraoperative navigation systems have been developed to aid surgeons in determining the adequacy of bony resection. Traditionally, adequacy of bony resection was determined through traditional intraoperative fluoroscopy. These new intraoperative systems not only provide intraoperative feedback, but allow for the generation of post-operative reports, which can be given to patients. These systems use a combination of intra-operative images to generate a virtual three-dimensional representation of the femoral head, and calculates a live alpha angle for perfect resection.

Evolution of Procedure

CAM Osteoplasty

The mainstay of treatment of femoroaceatabular impingement is correction of any underlying bony abnormality. Currently, this is performed through hip arthroscopy. A combination of burrs and shavers are used to remove excess bone and restore, as best as possible, normal anatomy. Careful attention must be paid to the labrum as well. Successful hip arthroscopy is dependent on correction of underlying CAM and pincer deformities, in addition to repair or reconstruction of labral pathology. Traditionally, proper correction of underlying bony abnormality was determined through the use of intraoperative fluoroscopy. This method, however, is quite subjective, and incomplete resection of bony pathology has been found to be a major predictor of poor outcomes following hip arthroscopy.
