Elbow, fractures and dislocations Elbow, fractures and dislocations. Comminuted extraarticular fracture of the distal humerus (white arrowheads), intersecting within the distal humeral fossae (*). This traction view was performed to exclude subtle intraarticular extension. 1 Series 2 ELBOW دکتر امید لیاقت

2 ELBOW Series 2 دکتر امید لیاقت Elbow, fractures and dislocations. Unstable unicondylar distal humeral fracture. Anteroposterior (AP) elbow radiograph shows comminuted fracture of the capitellum (black arrowheads). Disruption of the ulnotrochlear joint alignment (white arrows) indicates concomitant ligamentous injury that necessitates surgical repair. The injury is also open in this case. 2 Series 2 ELBOW دکتر امید لیاقت

3 ELBOW Series 2 دکتر امید لیاقت Elbow, fractures and dislocations. Comminuted bicondylar distal humeral fracture. Anteroposterior (AP) elbow radiograph shows fracture lines extending through the medial and lateral cortices of the distal humeral shaft, between the trochlea and capitellum, and between the trochlea and medial epicondyle (black arrows). Marked comminution is noted at the distal humeral fossae. The presence of the free trochlear fragment (outlined with white arrowheads) both increases difficulty of operative repair and increases risk of avascular necrosis. 3 Series 2 ELBOW دکتر امید لیاقت

4 ELBOW Series 2 دکتر امید لیاقت Elbow, fractures and dislocations. Olecranon fracture. Lateral elbow radiograph demonstrates comminuted (*) fracture of the olecranon with more than 3 mm of distraction of the proximal fracture fragment (double-ended white arrow) by the triceps tendon. This usually requires surgical repair. The radiocapitellar joint appears widened (black arrow), raising concern for concomitant ligamentous injury, which could be confirmed intraoperatively. 4 Series 2 ELBOW دکتر امید لیاقت

Elbow, fractures and dislocations. Coronoid process fracture Elbow, fractures and dislocations. Coronoid process fracture. Lateral elbow radiograph demonstrates a displaced fracture fragment (*) arising from the coronoid process (black arrowhead). 5 Series 2 ELBOW دکتر امید لیاقت

6 ELBOW Series 2 دکتر امید لیاقت Elbow, fractures and dislocations. Coronoid process fracture. Sagittal CT image indicates that the coronoid fracture fragment (*) involves more than 50% of the coronoid height (double-ended arrows), increasing the risk of elbow instability if not repaired. 6 Series 2 ELBOW دکتر امید لیاقت

7 ELBOW Series 2 دکتر امید لیاقت Elbow, fractures and dislocations. Radial head fracture. Anteroposterior (AP) elbow radiograph shows a minimally displaced fracture of the lateral radial head, involving slightly more than half of the articular surface and radial head rim. 7 Series 2 ELBOW دکتر امید لیاقت

Elbow, fractures and dislocations. Radial head fracture Elbow, fractures and dislocations. Radial head fracture. Postoperative radiograph shows this injury was treated with radial head replacement. 8 Series 2 ELBOW دکتر امید لیاقت

Elbow fractures and dislocations Elbow fractures and dislocations. Axial CT image was obtained post reduction and splinting for surgical planning purposes and shows acute fractures of the radial head and coronoid process. 9 Series 2 ELBOW دکتر امید لیاقت

10 ELBOW Series 2 دکتر امید لیاقت Elbow fractures and dislocations. Axial fat-suppressed T2 MRI through the distal humerus shows abnormal high T2 signal within the biceps brachii (bb), brachialis (b), and brachioradialis (br) muscle bodies, compatible with strain. Clinically, this mimicked biceps tendon rupture, but the tendon was found to be intact. 10 Series 2 ELBOW دکتر امید لیاقت
