2024年6月21日 · Coronoid process fractures may be diagnosed on a plain film series of the elbow, generally on a lateral or a 45° internal oblique view 4. CT is commonly necessary for fracture characterization of the fragment size, the degree of anteromedial involvement, and complex fracture-dislocation.

2024年6月21日 · The O'Driscoll classification system of coronoid process fractures distinguishes three types of coronoid process fractures of the ulna, and this classification system is useful when assessing further treatment options 1-4.

2022年9月24日 · Coronoid Fractures are traumatic elbow fractures that are generally pathognomonic for an episode of elbow instability. Diagnosis can be made using plain radiographs of the elbow. CT studies may be helpful for surgical planning. Treatment may be nonoperative for nondisplaced coronoid tip fractures with a stable elbow.

CT images demonstrate a fracture extending through the anteromedial facet of the coronoid process, indicating an increased risk for elbow instability. No other fractures. The alignment of the elbow is intact. Elbow joint effusion. Impression: The …

(1989) “Fractures of the coronoid process of the ulna.” J Bone Joint Surg Am. 71(9):1348-54. O’Driscoll SW, Jupiter JB, Cohen MS, Ring D, McKee MD. (2003) :Difficult elbow fractures ...

2024年6月3日 · Fractures of the coronoid process typically occur as part of more complex injury patterns, such as terrible triads, trans-olecranon fracture-dislocations, posteromedial rotatory injuries or Monteggia-like lesions. Each pattern is associated with a specific type of coronoid fracture with regard to shape and size and specific soft-tissue lesions.

2023年7月4日 · Summarize the common history and physical exam findings of patients with coronoid process fractures. Explain how to identify a coronoid fracture on imaging. Review the treatment options available for coronoid fractures and outline essential criteria to consider when choosing the appropriate treatment.

In isolated coronoid fracture, the fragment size is very small and due to the complex anatomy surrounding the coronoid radiographic imaging may not be sufficient. The purpose of this study was to evaluate the incidence of combined osteochondral and ligamentous injuries by magnetic resonance imaging (MRI) in 24 patients with an isolated coronoid ...

It is hard to tell the radial head fracture from the coronoid process fracture by anteroposterior and lateral X-ray film of the affected elbow. CT 3-D or MPR can accurately detect the position, severity and displacement of the fracture.

There is a minimally displaced acute intra-articular extending fracture involving the coronoid process of the ulna.
