Cartilage Imaging in Osteoarthritis
Semin Musculoskelet Radiol 2019; 23: 569-578 DOI: 10.1055/s-0039-1695720Osteoarthritis (OA) is the most common joint disease in the United States. The prevalence of OA is rising due to an aging population and increasing rates of obesity. Magnetic resonance imaging (MRI) allows an incomparable noninvasive assessment of all joint structures. Irreversible and progressive degradation of the articular cartilage remains the hallmark feature of OA. To date, attempts at developing disease-modifying drugs or biomechanical interventions for treating OA have proven unsuccessful. MRI-based cartilage imaging techniques have continued t...

Perspective on Idiopathic Subchondral, Osteochondral, and Chondral Lesions with Emphasis on the Knee
Semin Musculoskelet Radiol 2019; 23: 534-546 DOI: 10.1055/s-0039-1693978Subchondral, osteochondral, and chondral lesions of unknown cause are often encountered, especially in the knee joint. These are mainly idiopathic bone marrow edema syndrome, osteochondrosis dissecans, and cartilage delaminations. The literature on these diseases is sparse and often confusing and inconsistent. Because there is little evidence, this article was written as a perspective on these conditions. It offers an overview of the literature with personal comments and opinions based on observations from many years of clinical practice. The main goal...

Osteonecrosis of the Upper Extremity: MRI-Based Zonal Patterns and Differential Diagnosis
Semin Musculoskelet Radiol 2019; 23: 523-533 DOI: 10.1055/s-0039-1695719Regarding the upper extremity, osteonecrosis can relate to the humeral head and to any carpal bone, most commonly the lunate (Kienböck's disease), scaphoid (Preiser's disease and nonunion), and capitate bone (osteonecrosis of the capitate head). In children and adolescents, osteochondrosis is an important differential diagnosis at the epiphyses. Appropriate imaging of osteonecrosis depends on knowledge about blood supply, biomechanical load, and bone repair mechanisms. Contrast-enhanced MRI (ceMRI) enables the differentiation of up to three mostly...

Elbow Arthroplasty: From Normal to Failure
Semin Musculoskelet Radiol 2019; 23: 141-150 DOI: 10.1055/s-0039-1677698Total elbow arthroplasty is currently an established surgical treatment for several pathologies of the elbow. Although initially used primarily in the treatment of rheumatoid arthritis, indications for total elbow arthroplasty have expanded and now include trauma, primary and secondary osteoarthritis, fracture nonunion, and following neoplasm resection. Desired outcomes of elbow arthroplasty include decreasing patient pain, restoration of function and mobility, and prevention of or treatment for instability. In comparison with total elbow arthroplasty,...

Current Fixation Options for Elbow, Forearm, Wrist, and Hand Fractures
This article systematically reviews current classifications and treatment options for adult fractures of the distal humerus, radius, ulna, scaphoid, metacarpals, and phalanges. For each anatomic location, we discuss the salient imaging features to guide management decisions (conservative versus internal and/or external fixation). Specifically, we emphasize the amount of displacement, angulation, comminution, and/or intra-articular involvement typically guiding operative management for each fracture type. Through this understanding of the surgical indications, rationale behind different fixation options, and common complica...

Fractures Around the Shoulder: Radiologic Update on Surgical Fixation Techniques
Semin Musculoskelet Radiol 2019; 23: 099-108 DOI: 10.1055/s-0038-1677465Although radiologists are likely familiar with basic fracture patterns around the shoulder, certain fracture types in this area have particularly relevant and controversial clinical management issues. These include proximal humeral fractures, in which conservative management is favored but some patients receive surgical treatment; glenoid fractures and Hill-Sachs lesions, in which surgery may be performed depending on the amount of bone loss; and distal clavicular fractures, in which certain displaced fractures have high rates of nonunion, but there is...

Top-10 Tips for Getting Started with Magnetic Resonance Neurography
Semin Musculoskelet Radiol DOI: 10.1055/s-0039-1677727Magnetic resonance neurography (MRN), also known as MR neurography, is a dedicated imaging technique for the peripheral nerves, used both in a clinical setting and research. However, like any other new diagnostic processes, there are technical, cost, and patient selection issues to overcome as well as potential imaging pitfalls to recognize before MRN can be adopted efficiently into routine clinical practice. This review focuses on the 10 most important practical tips to get started with MRN with a view to shortening the time needed for radiologists to implement this cl...
