BACKGROUND Previous studies have indicated that hip and pelvis kinematics may be altered during functional tasks in persons with femoroacetabular impingement. The purpose of this study was to compare hip and pelvis kinematics and kinetics during a deep squat task between persons with cam femoroacetabular impingement and pain-free controls. METHODS Fifteen persons with cam femoroacetabular imp...

conclusions in 88% of primary osteoarthritis cases we found fai morphology on the ap pelvic radiograph, similarly to those found in the bibliography, and we considered naming primary osteoarthritis, secondary osteoarthritis caused by fai. in the majority of cases, early diagnosis with simple, cheap and easily accessible ap pelvic radiograph with low dose of radiation may also be warranted backg...

A mechanistic link has been suggested between cam-type femoroacetabular impingement and increased stress on the symphysis pubis. This retrospective study was conducted to determine whether there is an increased prevalence of osteitis pubis, as evidenced by imaging, in patients with femoroacetabular impingement compared with age-matched control subjects. Search of a radiologic database of a larg...

Femoroacetabular impingement is a disorder associated with labrochondral injury and the development of osteoarthritis. Although femoroacetabular impingement is a 3-dimensional disorder with variable size and extent of impingement between individuals, there are 2 primary types of hip impingement: Cam-type and Pincer-type. Cam-type impingement is the result of asphericity of the femoral head-neck...

OBJECTIVE The purpose of this article is to show the important radiographic criteria that indicate the two types of femoroacetabular impingement: pincer and cam impingement. In addition, potential pitfalls in pelvic imaging concerning femoroacetabular impingement are shown. CONCLUSION Femoroacetabular impingement is a major cause for early "primary" osteoarthritis of the hip. It can easily be...

Recent developments in hip arthroscopy techniques and technology have made it possible in many cases to avoid open surgical technique for treating pincer-type and cam-type femoroacetabular impingement and rather treating it arthroscopically. Early reports suggest favorable results using arthroscopic techniques. The frequency of complications reported for hip arthroscopy for all indications is g...

Femoroacetabular impingement is a relatively new clinical entity only recently described in the orthopedic literature. In this report, we document a severe case of hip joint osteoarthritis associated with cam-type impingement in a retired chiropractor.

Recently, femoroacetabular impingement has been recognised as a cause of early osteoarthritis. There are two mechanisms of impingement: 1) cam impingement caused by a non-spherical head and 2) pincer impingement caused by excessive acetabular cover. We hypothesised that both mechanisms result in different patterns of articular damage. Of 302 analysed hips only 26 had an isolated cam and 16 an i...

Femoroacetabular impingement (FAI) is a progressive pathology of hip joint affecting young adults causing hip pain and osteoarthritis. FAI results from contact secondary to abnormal morphology of proximal femur, femoral head-neck junction and acetabular rim. Two types of femoroacetabular impingement have been described: Pincer ve Cam impingement. Pincer impingement is caused by the overcoverage...

Femoroacetabular impingement is recognised as being a cause of labral tears and chondral damage. We report a series of five patients who presented with persistent pain in the hip after arthroscopy for isolated labral debridement. All five had a bony abnormality consistent with cam-type femoroacetabular impingement. They had a further operation to correct the abnormality by chondro-osteoplasty o...
