신형 지지체 생물재료의 안전성을 평가하기 위한 임상 시험

간략 요약

This is safety study. Subjects will be undergoing the surgical procedure of nerve biopsy. After routine surgery without grafting, patients develop swelling, redness, tenderness and dysesthesia at the biopsy site. In order to determine whether grafting is safe compared to not repairing the nerve, it is necessary to compare treated vs. untreated patients using systematic, sensitive and reproducible criteria.
