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...

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...

UNLABELLED Femoroacetabular impingement (FAI) is a clinical syndrome characterized by subtle abnormal morphology of the proximal femur and/or the acetabulum that leads to abnormal contact between the femoral neck and the acetabular rim during the hip range of motion. Traditionally, FAI has been managed safely and effectively with surgical hip dislocation; less invasive arthroscopic techniques a...

The etiology of degenerative joint disease of the hip remains unsolved. A precursor for some patients, especially younger ones, may be hip impingement. Repetitive microtrauma at maximal flexion can cause chronic pain from the abutment at the femoral head-neck junction caused by an abnormal offset. Chronic impingement from an aspherical head can lead to degenerative labral tears and acetabular c...

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...

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...

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 ...

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...

BACKGROUND Variations in position of the vermiform appendix considerably changes clinical findings. Retrocaecal appendicitis presents with slightly different clinical features from those of classical appendicitis associated with a normally sited appendix. K-sign looks for the presence of tenderness on posterior abdominal wall in the retrocaecal and paracolic appendicitis. This is the first case...
