Tarek M Hegazi, Jeffrey A Belair, Eoghan J McCarthy, Johannes B Roedl, William B Morrison
Injuries of the hip and surrounding structures represent a complex and commonly encountered scenario in athletes, with improper diagnosis serving as a cause of delayed return to play or progression to a more serious injury. As such, radiologists play an essential role in guiding management of athletic injuries. Familiarity with hip anatomy and the advantages and limitations of various imaging modalities is of paramount importance for accurate and timely diagnosis. Magnetic resonance (MR) imaging is often the modality of choice for evaluating many of the injuries discussed, although preliminary evaluation with conventional radiography and use of other imaging modalities such as ultrasonography (US), computed tomography, and bone scintigraphy may be supplementary or preferred in certain situations...

Snapping hip syndrome is an audible or palpable snap in a hip joint during movement which may be accompanied by pain or locking. It is typically seen in young athletes performing activities requiring repeated extreme movements of the hip. It may also follow a physical trauma, intramuscular injections or surgeries. There are two main forms of snapping hip: extra- or intra-articular. Extra-articular snapping hip is elicited by an abnormal movement of specific tendons and is divided into two forms: internal and external...

Synaptic dysfunctions and altered neuronal activity play major role in the pathophysiology of Alzheimer's disease (AD), with underlying mechanisms largely unknown. We report that in the prefrontal cortex of amyloid precursor protein-presenilin 1 and APP23 AD mice, baseline activity of pyramidal cells is disrupted by episodes of paroxysmal hyperactivity. Induced by spontaneous EPSC bursts, these incidents are prevalent in neurons proximal to amyloid plaques and involve enhanced activity of glutamate with metabotropic effects...

Ischiofemoral impingement (IFI) is an often unrecognized cause of hip pain caused by abnormal contact between the lesser trochanter and the ischium. To date, surgical treatment for those whose pain is not relieved by activity modification and steroid injections has not been defined. This study describes our imaging protocol and reports the results of arthroscopic, lesser trochanteric resections that were performed to treat this condition. Seven patients with symptomatic, MRI-documented IFI had ultrasound injections of ropivicaine and steroid into their ischiofemoral space...

UNLABELLED: To compare sports-related hip injuries on the basis of sex and age in a cohort of young athletes. A 5% random probability sample of all new patients' charts over a 10-year time period was selected for investigation. The most common hip injury diagnoses, sport at time of injury, mechanism (acute/traumatic vs. overuse), and types (bony vs. soft tissue) were compared by sex and age (preadolescent vs. adolescent). Descriptive and χ-analyses were carried out. The interaction of sex and age with respect to hip injury over time was examined by two-way (sex, age) analysis of variance...

Patients who have lateral hip pain historically have been diagnosed with trochanteric bursitis and treated with nonsteroidal anti-inflammatory medications, corticosteroid injections, and physical therapy. Although this strategy is effective for most patients, a substantial number of patients continue to have pain and functional limitations. Over the past decade, our understanding of disorders occurring in the peritrochanteric space has increased dramatically. Greater trochanteric pain syndrome encompasses trochanteric bursitis, external coxa saltans (ie, snapping hip), and abductor tendinopathy...

Greater trochanteric pain syndrome (GTPS) is a term used to describe disorders of the peritrochanteric region. This constellation of conditions includes greater trochanteric bursitis, gluteus medius (GM) tears, and external coxa saltans or snapping hip syndrome. Tears of the abductor mechanism, more specifically gluteus medius tears, have recently gained a considerable amount of interest in the orthopaedic literature. Abductor tears were first described by Bunker and Kagan in the late 1990s. They used the rotator cuff as an analogous structure to describe the pathological process associated with gluteus medius tears...

INTRODUCTION: Various surgical treatments have been proposed for greater trochanteric pain syndrome (GTPS) related to gluteal tendinopathy with partial thickness tears. The clinical results of endoscopic debridement without repair of these gluteal tears are not well known. The objectives of this study were to determine if this procedure leads to: (1) reduction of pain, (2) functional improvement, (3) patient satisfaction (on scale of 0 to 10). HYPOTHESIS: Endoscopic treatment without tendon repair provides short-term pain relief in patients with GTPS due to partial thickness gluteal tears...

Snapping hip syndrome is a relatively common problem that can be easily managed with conservative treatment. This syndrome can be divided into external, internal and intra-articular types. Internal snapping hip syndrome is the rarest amongst these and its etiology is not well understood. We report a unique case of osteochondroma arising from the anterior inferior iliac spine (AIIS), which caused the internal snapping hip syndrome with hip pain and restriction of activity. This rare case of snapping hip syndrome from the AIIS was treated surgically and the symptoms completely disappeared after excision of the tumor...

BACKGROUND: Arthroscopic release of the iliopsoas tendon may alleviate pain associated with internal snapping hip, but previous reports of physical function, hip strength, and muscle atrophy after surgery are mixed. HYPOTHESIS: The hips of patients who underwent arthroscopic iliopsoas release would demonstrate significantly reduced hip flexion strength and iliopsoas muscle volume when compared with their contralateral hips and the hips of patients who underwent hip arthroscopy without psoas release...

BACKGROUND: Despite overuse injuries being previously described as the most frequent in ballet, there are no studies on professional dancers providing the specific clinical diagnoses or type of injury based on the discipline. HYPOTHESIS: Overuse injuries are the most frequent injuries in ballet, with differences in the type and frequency of injuries based on discipline. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: This was a descriptive cross-sectional study performed between January 1, 2005, and October 10, 2010, on injuries occurring in professional dancers from leading Spanish dance companies who practiced disciplines such as classical, neoclassical, contemporary, and Spanish ballet...

High prices remain a formidable barrier for many people, especially those of low socioeconomic status, to adopt a healthier diet. The Food, Conservation, and Energy Act of 2008 mandated the U.S. Department of Agriculture (USDA) to conduct a pilot study to assess the impact of making fruits and vegetables more affordable for households in the Supplemental Nutrition Assistance Program (SNAP). Based on the USDA final report of the Healthy Incentives Pilot (HIP), a large-scale randomized trial in 2011-2012 that provided 30% rebate on targeted fruits and vegetables to 7500 study participants enrolled in the SNAP, we constructed a decision model to evaluate the cost-effectiveness of an expansion of the HIP to all SNAP households nationwide...

Arthroscopic techniques for the hip joint have evolved into endoscopic methods for extra-articular disorders. These endoscopic strategies provide a less invasive alternative to open procedures for traditionally recognized forms of pathology. Endoscopy has defined new disorders amenable to surgical correction and has redefined some of these existing disorders. The peritrochanteric and deep gluteal regions represent 2 of the most currently active areas of exploration. Peritrochanteric problems include trochanteric bursitis, full-thickness and partial-thickness tears of the abductors including the gluteus medius and minimus, and external coxa saltans (snapping iliotibial band)...

Snapping hip, or coxa saltans is a palpable or auditory snapping with movement of the hip joint. Extra-articular snapping is divided into external and internal types, and is caused laterally by the iliotibial band and anteriorly by the iliopsoas tendon. Snapping of the iliopsoas usually requires contraction of the hip flexors and may be difficult to distinguish from intra-articular coxa saltans. Ultrasound can be a useful modality to dynamically detect tendon translation during hip movement to support the diagnosis of extra-articular snapping...

We report on the dynamic sonographic findings of a 10-year-old avid female dancer who presented with symptoms of abrupt left hip motion and associated painful snapping sensation while performing lateral motions of the pelvis suggesting external snapping hip syndrome. Dynamic sonographic evaluation of both hips demonstrated that symptoms were due to gluteus maximus subluxation over the greater trochanter. This etiology of external snapping hip syndrome is rare with limited imaging descriptions in the literature...

BACKGROUND: Poor survival of THA implants in very young patients has been attributed to use of cemented implants, wear of conventional polyethylene, and the presence of morphologic deformities in the proximal femur or in the acetabulum. Few studies have reported the long-term results of ceramic-on-ceramic implants in THAs in patients younger than 20 years. QUESTION/PURPOSES: We determined: (1) the proportion of patients who experienced complications related to the ceramic bearing (squeaking, fracture); (2) the survivorship free from loosening and free from revision for any reason; (3) whether patients with osteonecrosis had inferior survivorship compared with patients whose surgical indication was all other diagnoses including sequelae of pediatric hip disorders (developmental dysplasia of the hip, Legg-Calvé-Perthes disease, slipped capital femoral epiphysis); and (4) clinical function...

Lateral hip snapping is a nosological entity that is often unknown to many orthopedists and even to some hip surgery specialists. It comprises palpable and/or audible snapping on the lateral face of the hip that is sometimes painful, caused by muscle-tendon friction on the greater trochanter during flexion and extension of the coxofemoral joint. In the following, we describe a new test for diagnosing lateral hip snapping, which is eminently clinical.
