title: Traumatic ulnar neuropathy from jet injection: case report.
abstract: The usefulness and relative safety of the technique of jet injection, mainly used in mass immunization, have been well established. A patient who developed a traumatic ulnar neuroma at the site of jet injection of swine flu vaccine is reported. This unusual and previously unreported complication of this procedure is thought to have occurred because of the patient's extremely small size and small muscles.
