Info

There is an echogenic line projecting from the ulnar olecranon process. It causes a reverberation artifact. It is the proximal end of the intramedullary nail inserted for the ulna fracture fixation. There is an encapsulated fluid around this nail tip. The triceps tendon is normal.
Case Discussion
The case shows olecranon bursitis caused by an intramedullary nail tip. The ulnar intramedullary nail was removed. There was no pus in the bursa.
