[Case of ulnar nerve palsy in a patient with a history of total elbow arthroplasty after abdominal surgery under general anesthesia].

Ulnar nerve palsy is a well recognized complication of the general anesthesia. We experienced a case of ulnar nerve palsy after abdominal surgery under general anesthesia in a patient with a history of total elbow arthroplasty and ulnar nerve translocation. It appears that pressure on medial epicondyle caused the palsy and that the position of the ulnar nerve has to be carefully examined before surgery in a patient with a history of total elbow arthroplasty and ulnar nerve translocation.
