OBJECTIVE to determine the prevalence of radiographic signs of femoroacetabular impingement (FAI) in asymptomatic adults and correlate them with data from physical examinations. METHODS We conducted a cross-sectional study with 82 asymptomatic volunteers, 164 hips, between 40 and 60 years of age, selected by convenience. They were submitted to anamnesis and clinical examination of the hip, an...

Hip arthroscopy is one of the most rapidly evolving arthroscopy techniques. It combines the benefits of a minimally invasive procedure and a short rehabilitation period. Improved instrumentation and technical skills have advanced our ability to accurately diagnose and treat various conditions. The role of this procedure continues to evolve with new indications that might change the outcome of d...

BACKGROUND Joint angle data from healthy subjects are necessary as baseline information. OBJECTIVE To analyze the problems of patients who struggle with activities of daily living (ADL) due to restricted range of motion and to provide ADL guidance based on objective data. METHOD An electromagnetic three-dimensional tracking system (FASTRAK) was used to quantify the hip, knee, and ankle angl...

BACKGROUND Our purpose was to evaluate outcome following arthroscopic treatment of femoroacetabular impingement (FAI) in middle-aged patients and to define risk factors for conversion to total hip arthroplasty (THA). METHODS This was a retrospective case series of 79 consecutive patients (40 to 65 years) undergoing arthroscopic treatment of FAI (follow-up ≥12 months). Outcome at follow-up was...

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...

Conventional treatment of mild slipped capital femoral epiphysis consists of fixation in situ with wires or screws. Recent contributions to the literature suggest that even a mild slip may lead to early damage of the acetabular labrum and adjacent cartilage by abutment of a prominent femoral metaphysis. It has been suggested that the appropriate treatment in mild slipped capital femoral epiphys...

BACKGROUND Dynamic RSA (dRSA) enables non-invasive 3D motion-tracking of bones and may be used to evaluate in-vivo hip joint kinematics including hip pathomechanics such as femoroacetabular impingement (FAI) and the biomechanical effects of arthroscopic cheilectomy and -rim trimming (ACH). The study aim was to evaluate the kinematic changes in the hip joint after ACH. METHODS Seven non-FAI af...

OBJECTIVE To determine the sensitivity and accuracy of direct MR arthrography in the diagnosis of intra-articular lesions associated with femoroacetabular impingement. MATERIAL AND METHODS We used direct MR arthrography to study 51 patients with femoroacetabular impingement who underwent arthroscopic hip surgery. Surgery demonstrated 37 labral tears, 44 lesions in the labral-chondral transiti...

Background and purpose - The role of pelvic incidence in hip disorders is unclear. Therefore, we undertook a literature review to evaluate the evidence on that role. Methods - A search was carried out on MEDLINE, SCOPUS, CENTRAL, and CINAHL databases. Quantitative analysis was based on comparison with a reference population of asymptomatic subjects. Results - The search resulted in 326 records:...
