Magnetic resonance imaging (MRI) has become a valuable technology for the diagnosis and treatment of femoroacetabular impingement (FAI). This article reviews the basic pathophysiology of FAI, as well as the techniques and indications for MRI and magnetic resonance arthrography. Normal MRI anatomy of the hip and pathologic MRI anatomy associated with FAI are also discussed. Several case examples...

Femoroacetabular impingement (FAI) is a relatively recently described but important cause of hip pain which frequently affects young and otherwise healthy patients. FAI results from an abnormal contact between the acetabulum and the femur secondary to a variety of morphologic abnormalities of the hip. There are two types of FAI, termed cam impingement and pincer impingement, which have distinct...

Altered gait kinematics in individuals with functional ankle instability (FAI) are thought to contribute to instability; however, research fi ndings are inconsistent. Findings may be clarifi ed with the use of a multisegment foot model and a coper group. Participants included 69 individuals: 23 with FAI, 23 controls, and 23 copers (individuals with a history of ankle sprain but no instability)....

Femoroacetabular impingement (FAI) causes pain and chondrolabral damage via mechanical overload during movement of the hip. It is caused by many different types of pathoanatomy, including the cam 'bump', decreased head-neck offset, acetabular retroversion, global acetabular overcoverage, prominent anterior-inferior iliac spine, slipped capital femoral epiphysis, and the sequelae of childhood Pe...

BACKGROUND There are limited data reporting outcomes after revision arthroscopic surgery for residual femoroacetabular impingement (FAI). HYPOTHESIS (1) Revision arthroscopic FAI correction results in improved outcomes, but they are inferior to those of primary arthroscopic FAI correction. (2) Improved postrevision radiographic parameters are predictive of better outcomes. STUDY DESIGN Coho...

Economic development and advancements in information technology contributed to the shift on accounting objective from commission responsibility view to decision-making useful view. The decision-making useful view claims that the accounting measurement methods should be changed to improve the usefulness of accounting information, to enable information users to make correct decisions. In addition...

At a conference the other day, while hotly debating the role of hip arthroscopic surgery in the management of osteoarthritis, a friend and colleague announced to the assembled throng, 'We know that hip arthroscopy doesn't work'. You would not have expected the Editor-in-Chief of this journal to remain silent at that moment and I certainly was not. However, what the statement did highlight, of c...

IMPORTANCE Elevated intraocular pressure (IOP) is a well-known adverse event associated with the fluocinolone acetonide implant (FAI), but no data are available regarding factors associated with increased risk of IOP elevation in patients treated with the FAI. OBJECTIVE To report risk factors that may predispose patients to elevated IOP after treatment with the FAI. DESIGN, SETTING, AND PAR...
