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 ...

Geometric abnormalities of the human hip joint, as found in femoroacetabular impingement (FAI) and acetabular dysplasia, alter hip biomechanics and may be the primary causes of osteoarthritis in young adults. However, empirical evidence of direct correlations between abnormal geometry, altered biomechanics, and osteoarthritis is scarce. Also, clinical measures used to diagnose FAI and dysplasia...

PURPOSE To determine factors associated with grade IV cartilage defects in the hip in patients undergoing hip arthroscopy with joint pain. METHODS Data from consecutive patients who underwent hip arthroscopy performed by a single surgeon over a period of 4 years were included in this study. The study group included 1,097 patients (491 women and 606 men; mean age, 37 years) who underwent hip a...

Femoroacetabular impingement syndrome is a common hip pathology significantly affecting not only the intra- and extra-articular structures but also the biomechanical function of the joint. Cam and pincer bony lesions have been extensively studied. However, during recent years, other types of extra-articular impingement between the pelvic and femoral bone have been investigated. When a prominent...

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 ...

Hip arthroscopy (HA) is considered to be a very difficult and demanding surgical procedure, special instruments, an image intensifier and a fracture table or hip distractor are required to access the hip joint, the most common and worldwide used HA technique is entering blindly to the central compartment with the use of fluoroscopy and continuous distraction; with the potential danger if perfor...

Introduction: For diagnosing some of the hip diseases, it is important to obtain the hip's range of motion. For example loss of internal rotation in the hip is one of the first signs of internal hip pathology and can be related to diagnoses, such as arthritis. Also, increase in femoral or acetablular anteversion usually demonstrates an increase in the internal rotation. Clinical hip examination...
