Snapping hip, or coxa saltans, presents as an audible or palpable snapping that occurs around the hip during movement and can be associated with or without pain. The prevalence of snapping hip is estimated to occur in up to 10% of the general population, but it is especially seen in athletes such as dancers, soccer players, weight lifters, and runners. Although the snapping sound can be readily heard, the diagnostic cause may be a clinical challenge. The causes of snapping hip have been divided into two distinct categories: extra-articular and intra-articular. Extra-articular snapping hip can be further subdivided into external and internal causes. Advances in imaging techniques have improved the diagnostic accuracy of the various causes of snapping hip, mainly by providing real-time imaging evaluation of moving structures during the snapping phase. Image-guided treatments have also been useful in the diagnostic work-up of snapping hip given the complexity and multitude of causes of hip pain. We discuss the common and uncommon causes of snapping hip, the advanced imaging techniques that now give us a better understanding of the underlying mechanism, and an image-guided diagnostic and therapeutic algorithm that helps to identify surgical candidates.
弹响髋，或称跳跃征髋，表现为在髋关节活动时出现可闻及或可触及的弹响，可伴有或不伴有疼痛。据估计，弹响髋在普通人群中的发生率高达10%，但在舞者、足球运动员、举重运动员和跑步运动员等运动员中尤为常见。尽管弹响声很容易听到，但诊断其病因可能是一项临床挑战。弹响髋的病因分为两大类：关节外和关节内。关节外弹响髋可进一步细分为外部和内部原因。成像技术的进步提高了对弹响髋各种病因的诊断准确性，主要是通过在弹响阶段对运动结构进行实时成像评估。鉴于髋部疼痛的病因复杂多样，图像引导治疗在弹响髋的诊断检查中也很有用。我们讨论了弹响髋的常见和罕见病因、使我们现在能更好地理解潜在机制的先进成像技术，以及有助于识别手术候选者的图像引导诊断和治疗算法。
