Ultrasonography of the pediatric elbow.

Ultrasound of the elbow can be incorporated into routine pediatric practice in the radiology department, emergency department, orthopedic clinic, and interventional suite. Ultrasound is complementary to radiography and magnetic resonance imaging for the evaluation of elbow pain in athletes with overhead activities or valgus stress, focusing on the ulnar collateral ligament medially and capitellum laterally. As a primary imaging modality, ultrasound can be used for a variety of indications including inflammatory arthritis, fracture diagnosis, and ulnar neuritis/subluxation.

Non-contrast MRI diagnosis of adhesive capsulitis of the shoulder.

Purpose: To investigate non-contrast MRI findings of clinical adhesive capsulitis.

Methods: 31 non-contrast, non-arthrographic, shoulder MRIs were evaluated for coracohumeral ligament thickness, rotator interval infiltration, and axillary recess thickening/edema.

Results: In detection of adhesive capsulitis, sensitivity is 76.

Resident Perspectives of an Interactive Case Review Following Independent Didactic Study as a Method of Teaching a Pediatric Imaging Curriculum.

Purpose: The ABR has recently changed the format of the board examination, in which the oral examination was replaced by a computer based multiple-choice test. The purpose of this study was to determine resident's perceptions of a new conference resembling the new ABR format.

Methods: Residents were requested to review a series of didactic pediatric imaging presentations prior to attending case conference.

Association of Gluteus Medius and Minimus Muscle Atrophy and Fall-Related Hip Fracture in Older Individuals Using Computed Tomography.

Purpose: The aim of this study was to determine an association between fall-related hip and/or pelvic fractures and gluteus medius and minimus atrophy.

Methods: Retrospective review of 64 patients with fall-related hip/pelvic fractures and 96 age- and sex-stratified controls was performed. Gluteus medius, gluteus minimus, tensor fascia lata, and iliopsoas atrophy was scored using a standard scale.

ABR Core Examination Changes That Affect Residency Candidate Decisions.

Purpose: The recent restructuring of the ABR core examination has prompted changes to radiology residency training. The purpose of this study is to determine how factors related to the core examination restructuring influenced radiology applicants' match decisions.

Methods: We surveyed 626 applicants to our institution's radiology residency, after the 2014 match.

Prevalence and pattern of gluteus medius and minimus tendon pathology and muscle atrophy in older individuals using MRI.

Purpose: To evaluate gluteus medius and minimus tendon pathology and muscle atrophy in older individuals using MRI.

Methods: A retrospective MRI study of 185 individuals was performed. The inclusion criterion was age ≥50.

Sonography of greater trochanteric pain syndrome and the rarity of primary bursitis.

Objective: Greater trochanteric pain syndrome is a common condition with clinical features of pain and tenderness at the lateral aspect of the hip. Diagnosing the origin of greater trochanteric pain is important because the treatment varies depending on the cause. We hypothesized that sonographic evaluation of sources for greater trochanteric pain syndrome would show that bursitis was not the most commonly encountered abnormality.

Vertebroplasty and kyphoplasty in the United States: provider distribution and guidance method, 2001-2010.

Objective: The purpose of this study was to determine the utilization by specialty and guidance method for vertebral augmentation (including vertebroplasty and kyphoplasty) in the United States from 2001 to 2010.

Materials And Methods: Using the 2001 through 2010 United States part B Medicare claims database, we studied the CPT-4 (Current Procedural Terminology, 4th ed.) codes used for thoracic (22520) and lumbar (22521) vertebroplasty, thoracic (22523) and lumbar (22524) kyphoplasty, and the method of radiologic guidance (76012 for fluoroscopy and 76013 for CT).

Common sonographic findings in the painful hip after hip arthroplasty.

Diagnosing the cause of hip pain in patients with hip arthroplasty can be challenging because of the numerous possible causes of pain and artifacts caused by the prosthetic components on computed tomography and magnetic resonance imaging. Sonography plays an important role in the diagnosis and management of these patients because the soft tissues surrounding the prosthetic joint are not obscured by artifacts and because sonography enables hands-on examination of the painful site, dynamic evaluation of moving structures, and comparison with the opposite side. Another advantage of sonography is the ability to perform sonographically guided diagnostic and therapeutic procedures.

Coloarticular fistula: A rare complication of revision total hip arthroplasty.

Fistula formation between bowel and total hip arthroplasty or revision arthroplasty hardware is rare. We present a case of a 78-year-old woman with protrusio of left hip arthroplasty and acetabular reconstruction hardware that caused direct perforation of the sigmoid colon and fistula formation between the sigmoid colon and the left hip joint. The patient underwent several joint debridements, sigmoid colectomy, and removal of all orthopedic hardware; she ultimately died after two prolonged hospitalizations.
