Diagnostic imaging may include ultrasound, plain radiography (x-ray imaging), Computed tomography scan (CT), and magnetic resonance imaging (MRI). [2] [4] A fat pad sign may be present on diagnostic imaging and may indicate a radial head fracture. [5] A diagnosed radial head fracture can be classified according to the Mason-Johnston system. [3]
The posterior fat pad is normally pressed in the olecranon fossa by the triceps tendon, and hence invisible on lateral radiograph of the elbow. [3] When there is a fracture of the distal humerus, or other pathology involving the elbow joint, inflammation develops around the synovial membrane forcing the fat pad out of its normal physiologic resting place.
Imaging such as an X-ray, MRI or ultrasound; Histology study; Ulnar nerve neuropathy at the elbow or the wrist can be assessed by testing for a positive Froment's sign. Little finger abduction and adduction can be tested as well. [12]
In children, there is a specific type of dislocation called a pulled elbow or subluxation seen when an extended elbow is pulled with force. [3] Frequently, these traumas can cause obvious deformities visible to the naked eye, but other times more advanced imaging (i.e. x-ray, CT, or MRI) is required to evaluate the extent of the damage.

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.
New York Yankees ace Gerrit Cole will have an MRI of his right elbow after experiencing issues in bouncing back following spring training starts. The 2023 AL Cy Young Award winner has been durable ...
The 37-year-old right-hander struggled at times last season, going 8-10 with a 4.56 ERA — the second highest ERA of his 11-year career — before being shut down in August due to concerns about ...
The composition of the triangular ligamentous structure on the lateral side of the elbow varies widely between individuals [1] and can be considered either a single ligament, [2] in which case multiple distal attachments are generally mentioned and the annular ligament is described separately, or as several separate ligaments, [1] in which case parts of those ligaments are often described as ...
