The radiologist has a number of roles not only in diagnosing but also in treating osteoporosis. Radiologists diagnose fragility fractures with all imaging modalities, which includes magnetic resonance imaging (MRI) demonstrating radiologically occult insufficiency fractures, but also lateral chest radiographs showing asymptomatic vertebral fractures. In particular MRI fragility fractures may have a nonspecific appearance and the radiologists needs to be familiar with the typical locations and findings, to differentiate these fractures from neoplastic lesions. It should be noted that radiologists do not simply need to diagnose fractures related to osteoporosis but also to diagnose those fractures which are complications of osteoporosis related pharmacotherapy. In addition to using standard radiological techniques radiologists also use dual-energy x-ray absorptiometry (DXA) and quantitative computed tomography (QCT) to quantitatively assess bone mineral density for diagnosing osteoporosis or osteopenia as well as to monitor therapy. DXA measurements of the femoral neck are also used to calculate osteoporotic fracture risk based on the Fracture Risk Assessment Tool (FRAX) score, which is universally available. Some of the new technologies such as high-resolution peripheral computed tomography (HR-pQCT) and MR spectroscopy allow assessment of bone architecture and bone marrow composition to characterize fracture risk. Finally radiologists are also involved in the therapy of osteoporotic fractures by using vertebroplasty, kyphoplasty, and sacroplasty. This review article will focus on standard techniques and new concepts in diagnosing and managing osteoporosis.

Objective: Diagnosis of a distal end radius fracture relies on various imaging studies. However, the relative usefulness of these studies is still a matter of some controversy. The aim of this study was to compare the intra-observer and inter-observer reliability of plain radiographs, standard computed tomography (CT) scans and mobile CT scans in the assessment of distal radius fractures as categorized by the Fernandez classification method. The secondary objective was to compare the dosages of radiation between the different imaging modalities. Material and Methods: Sixteen fresh cadaveric wrist bones were used in this experimental study. The desired fractures were created in the bones to mimic Fernandez types I-V fractures and plain radiographs were taken in 4 views. Standard CT and mobile CT scans were also taken with the fractured bones in the same four positions. Interobserver reliability was assessed using Kappa statistics to determine the diagnostic consistency among the nine observers. Inter-observer agreement was assessed based on the Fernandez classification system diagnoses. Results: Overall, the inter-observer agreement was substantial for the Fernandez classifications (Kappa range 0.636 0.727) in all types of imaging. For intra-observer agreement, the analysis found higher agreement for both standard CT scans and mobile CT scans. The standard CT images imparted a higher average dose of radiation than both the mobile CT scans and the plain radiographs.Conclusion: The mobile CT scan can provide an alternative imaging method for precise diagnosis of distal end radius fractures, with the additional benefits of mobility and lower radiation exposure.

Glenohumeral Osteoarthritis

Background Glenohumeral osteoarthritis (OA) carries a spectrum of morphology and wear patterns of the glenoid surface exemplified by complex patterns such as glenoid biconcavity and acquired retroversion seen in the B2 glenoid. Multiple imaging methods are available for evaluation of the complex glenoid structure seen in B2 glenoids. The purpose of this article is to review imaging assessment of the type B2 glenoid. Methods The current literature on imaging of the B2 glenoid was reviewed to describe the unique anatomy of this OA variant and how to appropriately assess its characteristics. Results Plain radiographs, magnetic resonance imaging, and standard 2-dimensional computed tomography (CT) have all shown acceptable assessments of arthritic glenoids but lack the detailed and highly accurate evaluation of bone loss and retroversion seen with 3-dimensional CT. Conclusion Accurate preoperative identification of complex B2 pathology on imaging remains essential in planning and achieving precise implant placement at the time of shoulder arthroplasty.
