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...

BACKGROUND A valid functional test, evaluating dynamic balance control, might be valuable clinic tool for evaluation of treatment outcome on patients with femoral acetabular impingement (FAI). OBJECTIVES The aim of this study was to evaluate criterion and divergent validity of the Star Excursion Balance Test (SEBT) on patients with bilateral FAI- changes, with unilateral clinical symptoms. ...

OBJECTIVES The number of surgical procedures performed each year to treat femoroacetabular impingement (FAI) continues to rise. Although there is evidence that surgery can improve symptoms in the short-term, there is no evidence that it slows the development of osteoarthritis (OA). We performed a feasibility study to determine whether patient and surgeon opinion was permissive for a Randomised ...

BACKGROUND An inverse relationship between better socioeconomic status (total household income, education or occupation) and stroke has been established in developed communities, but family size has generally not been considered in the use of socioeconomic status indices. We explored the utility of Family Average Income (FAI) as a single index of socioeconomic status to examine the association ...

OBJECTIVE Studies in rodents indicate a role of vitamin D in male reproduction, but the relationship between vitamin D and androgen levels in men is largely unexplored. We aimed to investigate the association of 25-hydroxyvitamin D [25(OH)D] levels with testosterone, free androgen index (FAI) and SHBG. Moreover, we examined whether androgen levels show a similar seasonal variation to 25(OH)D. ...

The proximal femur is abnormally shaped in patients with cam-type femoroacetabular impingement (FAI). Impingement may elicit bone remodeling at the proximal femur, causing increases in cortical bone thickness. We used correspondence-based shape modeling to quantify and compare cortical thickness between cam patients and controls for the location of the cam lesion and the proximal femur. Compute...

OBJECTIVES The objective of this study was to investigate cases of femoroacetabular impingement (FAI) and analyze the risk factors for a painful hip at skeletal maturity after Perthes disease. We hypothesized that FAI occurs as a sequela of Perthes disease and that coxa plana and triple osteotomy of the pelvis (TOP) may be risk factors. METHODS Ninety-five hips were included from 1981 to 2011...
