INTRODUCTION To analyze the X-ray and magnetic resonance imaging (MRI) features of acetabular labral tears, so as to improve the recognition of the disease. MATERIAL AND METHODS Imaging features of 19 patients with acetabular labral tears confirmed by arthroscopy were analyzed retrospectively. All cases were examined by X-ray. Fourteen patients underwent MRI examinations. RESULTS Seventeen ...

SYNOPSIS Ice hockey goaltenders, especially those who employ the butterfly technique, are a specialized population of athletes because of the unique physical demands that the position places on their lower extremities, specifically at the hip. It is no surprise that hip injuries are a common occurrence among goalies. A review of the biomechanical literature has demonstrated that stresses on the...

Over an eight-month period we prospectively enrolled 122 patients who underwent arthroscopic surgery of the hip for femoroacetabular impingement and met the inclusion criteria for this study. Patients with bilateral hip arthroscopy, avascular necrosis and previous hip surgery were excluded. Ten patients refused to participate leaving 112 in the study. There were 62 women and 50 men. The mean ag...

Objectives: Femoroacetabular impingement syndrome is a painful disorder of the hip formed by movements in joint between femoral head-neck junction and acetabular edge. The aim this study was to determine prevalence radiological femoroacetabular findings young, asymptomatic Turkish population. Methods: A total 1000 abdominal pelvic CT images were collected from patients aged 18–40 years. Measure...

conclusion the prevalence of radiological parameters associated with fai is high, even in an asymptomatic young population. this high frequency of features may suggest that the threshold values have been set too low in the current literature, or that these findings may reflect anatomical variation rather than true pathological abnormalities. background femoroacetabular impingement (fai) is one ...

 Two distinct types of FAI: Cam and rim or pincer impingement.  Pincer impingement is believed to result from abnormal extensión/contact (Bony prominence) of the anterior and/or posterior walls or acetabular roof relative to the center of the femoral head, causing an abutment of the acetabular rim against the femoral head-neck junction.  The term pincer impingement was defined in 2003 by Gan...

Femoroacetabular impingement is a cause of hip pain in adults and is potentially a precursor of osteoarthritis. Our aim in this study was to determine the prevalence of bilateral deformity in patients with symptomatic cam-type femoroacetabular impingement as well as the presence of associated acetabular abnormalities and hip pain. We included all patients aged 55 years or less seen by the senio...

PURPOSE The purposes of this study were to assess the presence of cam and pincer morphology in asymptomatic individuals with a negative femoroacetabular impingement test, and to determine and compare the ranges of alpha angle using two measurement methods. MATERIALS AND METHODS In total, 68 consecutive patients who underwent abdominopelvic computed tomography (CT) for reasons other than hip p...

Different aetiologies including the femoroacetabular impingement (FAI) may cause a painful hip, especially in young pa - tients. Two general types of femoroacetabular impingement have been described, the pincer- and the cam type impingement. The latter is characterized by a femoral deformity, usually a bump on the head-and-neck junction that impinges on the acetabular rim. The authors describe ...

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...
