Best Practice Case Studies-Elbow Dislocation

Video Transcription

Hi, this is Sagar Wagle, one of the musculoskeletal radiology fellows at Stanford University.  We have a 17 year old male presenting with elbow pain after a fall.  We can see that the radial head and ulna are both posteriorly dislocated with respect to the distal humerus.  We can see that the radial head is not normally articulating with the  capitellum and the ulna is not normally articulating with the trochlea.  These are post reduction radiographs and we can see that the radial head and ulna are now normally in position and the radial head and ulna are  normally articulating with the capitellum and trochlea.  I have another case of a 35 year old male after a motorbike accident. We can again see posterior dislocation of radial head and ulna.  There's a large amount of soft tissue air and there is also a fracture fragment with unclear donor site.  On post reduction radiograph, we can see that the radial head and ulna are normally located and we again see the fracture fragment.  Patient subsequently had a CT scan and on the 3D images, we can see that the large fracture fragment has come off  the coronary process of ulna.  Sometimes in these types of fracture, the fracture is surgically reduced because you can imagine with deficient coronoid process, it's easy for the ulna to dislocate posteriorly.  Our patient had a surgery, the displaced coronoid fracture fragment is brought in place and it's kept in place by fiber wire and suture anchor.  The patient also had some ligamentous injury and it was fixed with suture anchors here. Thank you for watching the video.

Video Summary

The video features Sagar Wagle, a musculoskeletal radiology fellow at Stanford University, discussing two cases of elbow dislocation. A 17-year-old male suffered posterior dislocation of the radial head and ulna following a fall, which was corrected post reduction. A 35-year-old male from a motorcycle accident had a similar dislocation alongside a fracture on the coronoid process of the ulna. A CT scan confirmed the fracture fragment origin, and surgical intervention was necessary to prevent further dislocation. The surgery included repositioning the fracture fragment using fiber wire and suture anchors, and treating ligamentous injury with suture anchors as well.
