PURPOSE: Quantitative MRI (QMRI) of the hip with sequences such as T1ρ and T2 mapping has been utilized to detect early changes in cartilage matrix composition. However, QMRI has not been performed in the presence of intra-articular contrast. Thus the purpose of this study was to evaluate the feasibility and use of QMRI during MR-arthrography (MRA) in femoracetabular impingement (FAI) patients. MATERIALS AND METHODS: Using a 3 Tesla MR-scanner, 10 FAI patients underwent a unilateral MRA and standard MRI of the hip joint...

Femoroacetabular impingement is the mechanical contact between the femur and the pelvis, frequently between the femur neck and the acetabular rim, whether due to a deformity of the former (cam type) or the latter (pincer type). However, there may be extraarticular causes of impingement. Together with the increased diagnosis of impingement, arthroscopic treatment is increasingly frequent and has become the standard treatment. This report analyzes a case of extraarticular hip impingement caused by contact between the femur and a prominent anteroinferior iliac spine (AIIS), probably due to a healed old avulsion and its later arthroscopic management...

INTRODUCTION: Minimal bone changes in the acetabulum and/or proximal femur, through mechanism known as femoroacetabular impingement, during flexion, adduction and internal rotation lead to early contact between femoral head-neck junction and acetabular brim, in anterosuperior region. Each additional pathological substrate which further decreases specified clearance provokes earlier onset of femoroacetabular impingement symptoms. CASE REPORT: We presented a 20-year-old male patient with groin pain, limping, positive impingement test, radiological signs of mixed form of femoroacetabular impingement and unrecognized chronic hypertrophic synovitis with earlier development of clinical hip symptoms than it has been expected...

BACKGROUND: As the prevalence of hip pathology in the younger athletic population rises, the medical community continues to investigate effective intervention options. Femoracetabular impingement is the morphologically abnormal articulation of the femoral head against the acetabulum, and often implicated in pre-arthritic hip conditions of musculoskeletal nature. Arthroscopic surgical decompression and non-surgical rehabilitation programs focused on strengthening and stability are common interventions...

UNLABELLED: Slipped capital femoral epiphysis (SCFE) may lead to symptomatic femoroacetabular impingement (FAI). We report our experience of arthroscopic treatment, including osteochondroplasty, for the sequelae of SCFE. Data were prospectively collected on patients undergoing arthroscopy of the hip for the sequelae of SCFE between March 2007 and February 2013, including demographic data, radiological assessment of the deformity and other factors that may influence outcome, such as the presence of established avascular necrosis...

BACKGROUND/AIM: Arthrosis of the hip is the most common cause of a hip joint disorders. The aim of this study was to present our experience in the application of a safe surgical dislocation of the hip in patients with minor morphological changes in the hip joint, which, through the mechanism of femoroacetabular impingement, cause damage to the acetabular labrum and adjacent cartilage as an early sign of the hip arthrosis. METHODS: We have operated 51 patients with different morphological bone changes in the hip area and resultant soft tissue damage of the acetabular labrum and its adjacent cartilage...

BACKGROUND: Heterotopic ossification (HO) is a known complication of hip arthroscopy. Our objective was to determine the effect of postoperative naproxen therapy on the development of HO following arthroscopic surgery for femoroacetabular impingement. METHODS: Between August 2011 and April 2013, 108 eligible patients were enrolled and randomized to take naproxen or a placebo for three weeks postoperatively. Radiographs were made at routine follow-up visits for one year following surgery...

Slipped upper femoral epiphysis (SUFE) is the most common hip disorder to affect adolescents. Controversy exists over the optimal treatment of severe slips, with a continuing debate between in situ fixation versus corrective surgery. We present our experience in a series of 57 patients presenting with severe unilateral SUFE (defined > 50°) managed with a subcapital cuneiform osteotomy. Between 2001 and 2011, 57 patients (35 male, 22 female) with a mean age of 13.1 years (9.6 to 20.3, SD 2.3) were referred to our tertiary referral institution with a severe slip...

Hip problems have increased especially among young ice hockey goalkeepers and those using the butterfly technique. Femoroacetabular impingement (FAI) is a common cause of the symptoms. Although hip impingement may also be symptomless, it may later predispose to joint damages, especially in case of goalkeepers who are loading their hip. Diagnosis of the impingement is important in order to lessen any harmful effects. Magnetic resonance imaging is the most important investigation in addition to the elucidation of patient history and clinical condition...

EDITORIAL
James H Lubowitz
Complications indicating revision after hip arthroscopy generally manifest within 24 months. Femoroacetabular cam or pincher impingement deformity under-resection is the primary indication for revision arthroscopy. Revision results in decreased pain and improved function, and primary and revision hip femoroacetabular impingement arthroscopic surgeons must be mindful of femoral cam lesion over resection, which could result in iatrogenic femoral neck fracture.

The purpose of this study was to determine patient-reported outcomes of patients with mild to moderate developmental dysplasia of the hip (DDH) and femoroacetabular impingement (FAI) undergoing arthroscopy of the hip in the treatment of chondrolabral pathology. A total of 28 patients with a centre-edge angle between 15° and 19° were identified from an institutional database. Their mean age was 34 years (18 to 53), with 12 female and 16 male patients. All underwent labral treatment and concomitant correction of FAI...

Femoroacetabular impingements (FAI) are quite frequent among young athletes. An early detection is essential in order to prevent more labral and cartilage damage. Conservative treatment should not focus on forcing the full range of motion but on restoring a good muscle balance around the joint and a better lower limb dynamic stability and control. The patient should be educated to master the end of hip range of motion during his activities. If the outcome is not satisfactory, a surgical treatment is offered...

Different disorders around the hip joint have been diagnosed in athletes of all levels. Pathologies such as femoro-acetabular impingement (FAI) are responsible for lower performance during sports and early onset osteoarthrosis of the hip joint. This article emphasizes on the diagnosis and early treatment of FAI in young athletes. It is meant to raise concern about this relatively new pathology and hence avoid the deleterious results for the hip joint associated with late diagnosis.

There is an increased risk of fracture following osteoplasty of the femoral neck for cam-type femoroacetabular impingement (FAI). Resection of up to 30% of the anterolateral head-neck junction has previously been considered to be safe, however, iatrogenic fractures have been reported with resections within these limits. We re-evaluated the amount of safe resection at the anterolateral femoral head-neck junction using a biomechanically consistent model. In total, 28 composite bones were studied in four groups: control, 10% resection, 20% resection and 30% resection...

The extra-articular impingement of the greater trochanter against the ileum is an underrated cause of early dislocation in total hip arthroplasty. In this preliminary study, the authors assess the effectiveness of an anterior longitudinal osteotomy of the greater trochanter for preventing dislocation. A total of 115 patients underwent a total hip arthroplasty through a posterolateral approach. All patients underwent clinical and radiological follow-up at 1, 3, and 6 months. No dislocation was reported. All patients demonstrated fast recovery of range of motion and walking...

BACKGROUND: Three-dimensional (3-D) delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) helps quantify biochemical changes in articular cartilage that correlate with early-stage osteoarthritis. However, dGEMRIC analysis is performed slice by slice, limiting the potential of 3-D data to give an overall impression of cartilage biochemistry. We previously developed a computational algorithm to produce unfolded, or "planar," dGEMRIC maps of acetabular cartilage, but have neither assessed their application nor determined whether MRI-based grading of cartilage damage or dGEMRIC measurements predict intraoperative findings in hips with symptomatic femoroacetabular impingement (FAI)...

BACKGROUND: The precise etiology of cam impingement continues to be incompletely understood. The prevailing hypothesis posits that the deformity arises as a developmental injury prior to skeletal maturation. There is a possible evolutionary role, with an aspherical femoral head affording upright humans better stability. We set out to identify the antiquity of the cam deformity to better understand the comparative roles of modern behavior and evolution in its development. METHODS: We used 249 physical specimens of femora from the Libben osteological collection, a set of bones from an ancient population who lived between the eighth and the eleventh century...

Hip arthroscopy is an increasingly common procedure, particularly for the treatment of femoroacetabular impingement. Various complications have been previously reported, and the authors sought to further evaluate the safety of this procedure. This study was conducted to identify the incidence of femoral neck fracture as well as treatment and outcomes after arthroscopic femoroplasty. In April 2013, a survey was administered to 28 established hip arthroscopists regarding the breadth of their experience, including the total number of hip arthroscopies and proximal femoroplasties performed and the number of postoperative femoral neck fractures...

BACKGROUND: Femoroacetabular impingement is a common cause of hip pain in young adults. Several preoperative risk factors for poor outcomes with surgery have been identified; however, to our knowledge, no study has attempted to determine the effect of psychiatric comorbidity on outcomes with femoroacetabular impingement surgery. METHODS: A retrospective review was performed on active-duty patients at one institution undergoing surgery for femoroacetabular impingement over five years...
