The disappearing needle.
This is a report of an unusual surgical curiosity involving the median nerve at the wrist. A sewing needle, which penetrated the region of the wrist joint anteriorly, unknown to the patient, also penetrated the median nerve without causing any initial discomfort or neurological deficit. There was no damage to the nerve but locating the "disappearing" needle at operation was difficult.
