“…MRI may play a role in detecting occult fractures and osteochondral lesions that can be missed on radiographs and CT. 16 MRI may also be useful in the acute phase for evaluating high-performance athletes with elbow dislocations because it has a higher sensitivity for detection and is better for characterizing ligamentous injuries. 14 Magnetic resonance arthrography (MRA) is generally performed in the chronic setting to assess posterolateral rotatory subluxation and severe valgus injuries, and it can guide arthroscopic and surgical intervention.…”

The elbow is a joint composed of three different articulations all included in the same synovial capsule, with a complex anatomy that allows two kinds of motion: flexion-extension and pronation and supination. Stabilization of the elbow is provided by osseous and ligamentous structures.When assessing the elbow in the traumatic setting, the mechanism of injury determines the pattern of osseous and ligamentous lesion, with potential important implications on elbow instability. The role of the radiologist in the assessment of the traumatic elbow requires an understanding of the most common injury mechanisms in traumatic elbow injuries. This knowledge facilitates the detection of potential secondary occult bone and soft tissue injuries that could lead to chronic instability.We analyze the acute patterns of injury of the osseous, ligamentous, musculotendinous, and neurovascular structures, with a focus on the most commonly used classifications of fractures and fracture-dislocations. We also discuss the therapeutic management of these injuries, with mention of the most frequently used surgical techniques and the commonly expected posttreatment findings.Finally, we review the repetitive microtrauma patterns of injury of the elbow joint structures and the most common pitfalls in the interpretation of elbow imaging.

“…MRI is the modality of choice for the detection of radiographically occult fractures, particularly of the radial head, which are often suspected on the basis of persistent pain or joint effusion (Figure 6). 7 Bone marrow edema can also help to define mechanisms and discrete patterns of injury, which are encountered in both recreational and elite athletes. For instance, both medial epicondylitis (golfer’s elbow) and lateral epicondylitis (tennis elbow) can be seen in association with bone marrow edema.…”

Context:The elbow is a complex joint and commonly injured in athletes. Evaluation of the elbow by magnetic resonance imaging (MRI) is an important adjunct to the physical examination. To facilitate accurate diagnosis, a concise structured approach to evaluation of the elbow by MRI is presented.Evidence Acquisition:A PubMed search was performed using the terms elbow and MR imaging. No limits were set on the range of years searched. Articles were reviewed for relevance with an emphasis of the MRI appearance of normal anatomy and common pathology of the elbow.Results:The spectrum of common elbow disorders varies from obvious acute fractures to chronic overuse injuries whose imaging manifestations can be subtle. MRI evaluation should include bones; lateral, medial, anterior, and posterior muscle groups; the ulnar and radial collateral ligaments; as well as nerves, synovium, and bursae. Special attention should be paid to the valgus extension overload syndrome and the MRI appearance of associated injuries when evaluating throwing athletes.Conclusion:MRI evaluation of the elbow should follow a structured approach to facilitate thoroughness, accuracy, and speed. Such an approach should cover bone, cartilage, muscle, tendons, ligaments, synovium, bursae, and nerves.
