The video below demonstrates what is seen on ultrasound after a failed ulnar nerve transposition.
The nerve conduction studies and EMG data is shown for reference.
This patient had a history of multiple injuries to his bilateral arms over the years, including bilateral humeral fractures as a child, extensive third degree burns, bilateral rotator cuff tears requiring surgery, and two carpal tunnel surgeries on each hand.
He had a right ulnar nerve transposition done approximately 6-7 years ago in Red Deer, Alberta for symptoms of right fourth and fifth digit sensory loss, forearm and elbow pain, and weakness in finger flexion. The surgery improved most of his weakness, but he has been struggling with ongoing sensory loss and pain in the forearm and hand. He also complains of pain and stiffness in the right elbow. He notes intermittent swelling in the elbow joint as well, usually at the end of the day. He has difficulty using a hammer and shifting gears in his truck secondary to elbow pain and weakness.
