“…22 Magnetic resonance imaging is the test of choice for valgus instability. Nonenhanced MRI is 57% to 79% sensitive and 100% specific for MCL tears, whereas magnetic resonance arthrogram with saline or gadolinium is 97% sensitive and 100% specific.…”

The elbow comprises a complex of bony and ligamentous stabilizers that provide both primary and secondary constraints to elbow instability. Through trauma and overuse, classic instability patterns arise by loss of these important stabilizers. The diagnosis of elbow instability can made using specific examination maneuvers and testing to diagnose the clinical pattern. This article reviews the elbow’s unique anatomy and biomechanical characteristics and these are applied when reviewing the maneuvers and testing used to diagnose elbow instability.

“…It is a stabilizer of the elbow when the joint is flexed > 90 degrees. 4 The transverse bundle of the LCL is a thickening of the joint capsule and does not significantly contribute to elbow stability. It runs from the distal attachment of the posterior bundle of the LCL to the distal attachment of the anterior bundle of MCL, from the olecranon to the coronoid process.…”

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.
