Objective: To determine the spectrum of non-interventional radiology fellowship programs in institutions that offer both a radiology residency program and one or more non-interventional radiology fellowship programs.

Methods: Institutions offering both radiology residency and non-interventional radiology fellowship programs were identified using publicly available websites. The non-interventional radiology fellowship programs were categorized into "traditional" (neuroradiology, breast imaging, abdominal imaging, musculoskeletal imaging, thoracic imaging, pediatric radiology, and nuclear medicine) and "nontraditional" fellowship programs.

Imaging plays a central role in the postoperative management of acromioclavicular (AC) joint separations. There are more than 150 described techniques for the surgical management of AC joint injuries. These procedures can be categorized as varying combinations of the following basic techniques: a) soft-tissue repair, b) trans-articular AC joint fixation, c) coracoclavicular (CC) fixation, d) non-anatomic reconstruction of the CC ligaments, e) anatomic reconstruction of the CC ligaments, f) distal clavicle resection, and g) dynamic muscle transfer.

Despite improved strategies to prevent prosthetic joint infection, as the total number of joint replacements increases, so does the absolute number of infections. Radiography serves as the first-line imaging modality for the assessment of a suspected prosthetic joint infection. Additionally, serial radiographs acquired after a surgery to eradicate a prosthetic joint infection are an important clinical tool.

The floating shoulder refers to a subset of complex shoulder injuries that typically occur in the setting of high-energy trauma. Identification of the full extent of complex shoulder injuries with computed tomography may have critical implications in patient management. The goals of this article are to review the anatomy, definition, imaging evaluation, and treatment of floating shoulder injuries.

Objective: Contrast material often extends from the radiocarpal joint into the proximal soft tissues adjacent to the ulnar aspect of the ulnar styloid during single-compartment radiocarpal joint MR arthrography of the wrist. The hypothesis of this study was that this is a common finding unrelated to symptoms or examination technique.

Materials And Methods: Wrist MR arthrograms were retrospectively reviewed in consensus by two radiologists.

Rib fractures are the most common form of blunt thoracic injury. Multiple rib fractures are an important indicator of trauma severity, with increased morbidity and mortality occurring with increasing numbers of rib fractures, especially in the elderly. Thoracic cage injuries may be associated with concomitant and potentially life-threating injuries.

Lisfranc Injury: Current Concepts.

Radiol Clin North Am

November 2018

Lisfranc injuries range from sprain to fracture-dislocation. Radiologists must have a thorough understanding of anatomy, mechanisms, and patterns of these injuries to diagnose and help clinicians assess treatment options and prognosis. The initial imaging evaluation of patients with a suspected Lisfranc injury consists of non-weight-bearing radiographs.

Proximal femoral fragility fractures are common and result in significant morbidity and mortality along with a considerable socioeconomic burden. The goals of this article are to review relevant proximal femoral anatomy together with imaging, classification, and management of proximal femoral fragility fractures, and their most common complications. Imaging plays an integral role in classification, management and follow-up of proximal femoral fragility fractures.

Anterior cruciate ligament reconstruction is a commonly performed orthopaedic procedure which has increased in frequency over the past decade. There are a variety of fixation devices used to secure grafts within the femoral and tibial tunnels during the reconstruction procedure. An understanding of the expected appearance of the varied hardware utilized for reconstruction graft fixation, and their potential complications is important in the review of post-operative imaging.

Scapholunate instability is the most common form of carpal instability. Imaging (especially radiography) plays an important role in the staging, management and post-operative follow-up of scapholunate (SL) instability. The goals of this article are to review the pre-operative staging of SL instability, the surgical options for repair and reconstruction of the SL ligament, along with the normal postoperative imaging findings as well as complications associated with these surgical options.

Scapholunate (SL) instability is the most common form of carpal instability. Imaging (especially radiography) plays an important role in the staging, management, and postoperative follow-up of SL instability. In the final stage of SL instability, known as scapholunate advanced collapse, progressive degenerative changes occur at the carpal level.

Rationale And Objectives: Burnout is a psychological syndrome composed of emotional exhaustion, depersonalization, and sense of lack of personal accomplishment, as a result of prolonged occupational stress. The purpose of our study was to determine the prevalence of burnout among current musculoskeletal radiology fellows and to explore causes of emotional stress.

Materials And Methods: A 24-item survey was constructed on SurveyMonkey using the Maslach Burnout Inventory.

The overhead-throwing athlete is susceptible to a variety of predictable disease entities affecting the shoulder and elbow. While the pathophysiology and nomenclature of these diseases are ubiquitous throughout the clinical literature, this information is sparse within the radiology domain. We provide a comprehensive review of these unique injuries with accompanying imaging features in an effort to enhance the role of the radiologist during the management of the overhead thrower.

Objective: Burnout is a job-related psychological syndrome with three aspects: emotional exhaustion, depersonalization, and perceived lack of personal accomplishment. Burnout is associated with deleterious effects on both workers and their work. When burnout affects physicians, their well-being, longevity, and care of patients are at risk.

 The carpal boss is an osseous protuberance occurring variably along the dorsum of the second or third metacarpal base, lacking a standardized definition.  We sought to characterize the dorsal second and third carpometacarpal joints in the general population on computed tomography (CT) to better define this variant anatomy.  A total of 129 wrist CT studies were reviewed.

The wrist is disposed to a variety of instability patterns owing to its complex anatomical and biomechanical properties. Various classification schemes have been proposed to describe the different patterns of carpal instability, of which the Mayo classification is the most commonly used. Understanding the concepts and pertinent terminology of this classification scheme is important for the correct interpretation of images and optimal communication with referring physicians.

Most of the destructive joint disease necessitating arthoplasty is the result of an insidious and protracted process that occurs over the course of many years. However, there are a variety of diseases that may result in a rapid progressive deterioration of a joint. We describe both the common and less common etiologies of rapidly destructive arthropathy that one should consider, with imaging examples, and present discriminative factors when present.
