OBJECTIVES The aim of this study was to systematically review the literature on measurement of muscle strength in patients with femoroacetabular impingement (FAI) and other pathologies and to suggest guidelines to standardise protocols for future research in the field. METHODS The Cochrane and PubMed libraries were searched for any publications using the terms 'hip', 'muscle', 'strength', and...

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:...

Introduction Abnormal morphology of the anterior inferior iliac spine (AIIS) is a rarely recognized but important source of extra-articular hip impingement. Chronic progressive symptoms of stiffness and limitation of hip motion with persistent groin pain may place significant restriction on activity. Concomitant femoroacetabular impingement is often present but recognition and effective treatme...

CONTEXT Femoroacetabular impingement (FAI) was first described by Ganz in 2003 and is a significant cause of decreased function and mobility. Femoroacetabular impingement must be treated in an individualized, goal-oriented, stepwise fashion. This protocol was developed with biomechanical considerations of soft tissue and bony structures surrounding the hip joint. EVIDENCE ACQUISITION The PubM...

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...

AIMS The aim of this study was to establish preoperative factors associated with a good outcome in the surgical treatment of femoroacetabular impingement. METHODS A prospective study including 253 consecutive patients (280 hips) was carried out. We defined a "good" score as one which had either a 20 point improvement from preoperative to 12 months postoperative follow-up, or a score of over 8...

OBJECTIVE The aim of this study was to evaluate the association of the anatomical and functional characteristics with therapeutic failure in patients with femoroacetabular impingement, who underwent hip arthroscopy. MATERIALS AND METHODS A cohort study was performed on 179 patients with femoroacetabular impingement who underwent hip arthroscopy between 2004 and 2012. The demographic, anatomic...

INTRODUCTION AND OBJECTIVES Femoroacetabular impingement is probably the most common mechanism that leads to the development of early cartilage and labral damage in the non-dysplastic hip. The objective was to evaluate the outcomes of hip arthroscopy as a treatment for femoroacetabular impingement in patients with high level of function. MATERIAL AND METHODS A prospective study was performed ...
