Abstract

The fingers are among the most commonly injured structures in traumatic injuries resulting from sports and work. Finger injuries encompass a broad spectrum of injuries to bone and soft tissues, including tendons, ligaments, and cartilage. The high resolution of 3T MRI with dedicated surface coils allows for optimal assessment of the intricate soft tissue structures of the fingers. There have been several reports on detailed MRI features of the basic anatomy and common pathological findings of the finger and hand. Understanding the normal anatomy and familiarization with common traumatic lesions of the ligaments, tendons, and pulleys of the fingers on high-resolution MRI will allow radiologists to perform accurate preoperative evaluations of traumatic hand lesions. The purpose of this study is to review the normal hand anatomy and common traumatic lesions of the finger on high-resolution MRI and correlate them with surgical findings.

손가락은 일상생활과 스포츠 활동 중에 가장 흔하게 손상될 수 있는 구조물이다. 손가락 손상은 손가락의 뼈와 인대, 연골을 포함한 연부조직까지 다양한 구조물의 손상을 포함한다. 특수 표면코일을 이용한 고해상도 3 테슬라 자기공명영상을 이용하여 복잡한 연부조직 구조물들을 평가할 수 있다. 손가락과 손의 기본 해부학과 흔한 병변의 자기공명영상 소견들에 대한 기존의 보고들이 있다. 손가락의 인대, 건, 도르래 등 여러 구조물의 기본 해부학과 흔한 외상성 병변의 영상학적 소견의 이해는 다양한 손의 외상성 병변에 대한 정확한 평가를 가능하게 한다. 본 눈문에서는 손가락의 기본 해부학적 구조 및 흔한 외상의 자기공명영상 소견을 복습하고, 실제 수술장 소견과 연관 지어 이해를 돕고자 한다.
