Dynamic Hip Examination for Assessment of Impingement During Hip Arthroscopy.
Arthroscopic procedures for treatment of hip pathology are growing exponentially as a result of continued improvements in the understanding of intra- and extra-articular hip anatomy and technological advancements in instrumentation. Nevertheless, it has been reported that the main cause of revision hip arthroscopy is related to a suboptimal intrasurgical management of the abnormal morphology in femoroacetabular impingement (FAI). Under-resection, over-resection, and in some cases combined under-resection and over-resection at different locations of the cam lesion at the femoral head-neck junction may lead to poor outcomes as a result of residual impingement or the iatrogenic creation of structural instability. Thus, an intraoperative assessment technique capable of revealing in real time the effect of the resection is vital for a successful procedure. Therefore, we present a technical note describing our preferred method to dynamically assess overall hip range of motion, motion at risk, and evaluation of the osteoplasty after surgical correction of FAI.
