The fascia lata, or deep fascia of the thigh, is a complex anatomic structure that has not been emphasized as a potential source of pelvic and hip pain. This structure represents a broad continuum of fibrous tissue about the buttock, hip, and thigh that receives contributions from the posteriorly located aponeurotic fascia covering the gluteus medius muscle and from the more laterally located iliotibial band (ITB). At the pelvis and hip, the ITB consists of three layers that merge at the lower portion of the tensor fasciae latae muscle. The gluteal aponeurotic fascia and ITB merge at the buttock and hip before extending inferiorly to the Gerdy tubercle at the anterolateral tibia. Injuries to these anatomic structures are an underdiagnosed cause of pain and disability and may clinically mimic more common processes affecting the hip and proximal thigh. Categories of disease include overuse injuries, traumatic injuries, degenerative lesions, and inflammatory lesions. Familiarity with the anatomy and pathologic conditions of the fascia lata and its components is important in their recognition as a potential source of symptoms. This article illustrates the anatomy of this complex fascia through anatomic-pathologic correlation and describes the magnetic resonance imaging appearances of the pathologic conditions involving it.
阔筋膜，或大腿深筋膜，是一个复杂的解剖结构，尚未被强调为骨盆和臀部疼痛的潜在来源。该结构代表了臀部、髋部和大腿周围的一个广泛的纤维组织连续体，它接受来自覆盖臀中肌的后位腱膜筋膜和更外侧的阔筋膜张肌（ITB）的贡献。在骨盆和髋部，ITB 由三层组成，在阔筋膜张肌的下部融合。臀筋膜腱膜和 ITB 在臀部和髋部融合，然后向下延伸至胫骨前外侧的 Gerdy 结节。这些解剖结构的损伤是疼痛和残疾的一个被低估的原因，可能在临床上类似于更常见的影响髋关节和大腿近端的过程。疾病类别包括过度使用损伤、创伤性损伤、退行性病变和炎症性病变。熟悉阔筋膜及其组成部分的解剖和病理状况对于将其识别为潜在症状来源非常重要。本文通过解剖-病理相关性说明了这种复杂筋膜的解剖结构，并描述了涉及它的病理状况的磁共振成像表现。
