摘要

大多数肌肉撕裂发生在下肢，尤其是腘绳肌。腘绳肌复合体由半膜肌（SM）、半腱肌（ST）和股二头肌（BF）组成。它们起源于坐骨粗隆，当BF肌插入腓骨头部时，ST肌和SM肌连接到胫骨内侧。腘绳肌主要是髋关节伸肌和膝关节屈肌。撕裂主要发生在运动练习中，特别是在强力拉伸或高速跑步时，典型的部位根据其在肌肉解剖中的位置进行分组和分类。短跑损伤和拉伸损伤分别影响BF和SM。MRI和US是腘绳肌损伤诊断、治疗和预后的关键补充方式，因为损伤长度、结缔组织受累程度和撕裂位置决定了其演变、恢复策略和重返比赛。©RSNA, 2025年。

MRI and US in Hamstring Sports Injury Assessment: Anatomy, Imaging Findings, and Mechanisms of Injury.

Most muscle tears occur in the lower extremities, especially in the hamstrings. The hamstring muscle complex consists of the semimembranosus (SM), semitendinosus (ST), and biceps femoris (BF) muscles. They originate from the ischial tuberosity, and while the BF inserts into the head of the fibula, the ST and SM muscles attach to the medial aspect of the tibia. The hamstrings are primarily hip extensors and knee flexors. Tears mostly occur during sport practice, particularly during forceful stretching or high-speed running, and typical sites are grouped and classified according to their location within the muscle anatomy. Sprint and stretching injuries typically affect the BF and SM, respectively. MRI and US are key complementary modalities for the diagnosis, treatment, and prognosis of hamstring injuries, as injury length, connective tissue involvement, and tear location determine evolution, recovery strategies, and return to play. ^©RSNA, 2025.

期刊介绍： Launched by the Radiological Society of North America (RSNA) in 1981, RadioGraphics is one of the premier education journals in diagnostic radiology. Each bimonthly issue features 15–20 practice-focused articles spanning the full spectrum of radiologic subspecialties and addressing topics such as diagnostic imaging techniques, imaging features of a disease or group of diseases, radiologic-pathologic correlation, practice policy and quality initiatives, imaging physics, informatics, and lifelong learning. A special issue, a monograph focused on a single subspecialty or on a crossover topic of interest to multiple subspecialties, is published each October. Each issue offers more than a dozen opportunities to earn continuing medical education credits that qualify for AMA PRA Category 1 CreditTM and all online activities can be applied toward the ABR MOC Self-Assessment Requirement.
