Microinstability and ligament teres lesions are emergent topics on the hip pathology. These entities are an increasingly recognized cause of persistent hip pain and should be considered in the differential diagnosis of the patient with hip pain. Conventional (non-arthrographic) CT and MR have a very limited role in the evaluation of these entities. CTa and MRa have emerged as the modalities of choice for pre-operative imaging of ligamentum teres injuries and microinstability. To date, pre-operative imaging detection of these pathologies is not widespread but with appropriate imaging and a high index of suspicion, preoperative detection should improve. This article discusses current concepts regarding anatomy, biomechanics, clinical findings, diagnosis and treatment of ligament teres lesions and microinstability.
髋关节微不稳和圆韧带有病变是髋关节病理的新兴话题。这些病变是持续性髋关节疼痛的日益被认识的原因，在髋关节疼痛患者的鉴别诊断中应考虑到这些病变。传统（非关节造影）CT 和 MRI 在这些病变的评估中作用非常有限。CTA 和 MRa 已成为圆韧带损伤和微不稳术前影像学检查的首选方法。迄今为止，这些病变的术前影像学检测并不广泛，但随着适当的影像学检查和高度怀疑，术前检测应该会得到改善。本文讨论了圆韧带病变和微不稳的解剖、生物力学、临床发现、诊断和治疗的当前概念。
