Conflicts, snapping and instability of the tendons are common, and ultrasound (US) is the method of choice for evidencing these conditions thanks to the possibility to perform dynamic maneuvers during imaging studies. A conflict can occur between a tendon and a bone structure, other tendons, the retinacula or pulleys. Snapping can occur due to instability caused by rupture of the retinaculum, conflict between a thickened retinaculum and a bone prominence or due to an abnormal position of the tendon. Instability can occur due to insufficient ability of the retinaculum to keep the tendons in the bone groove or its failure to hold the tendons applied to the bone.The technique for evidencing conflicts, snapping and instability of the tendons is very demanding because it requires a thorough knowledge of the US appearance and dynamic maneuvers. However, at the present time US examination completed with dynamic maneuvers is the investigation of choice for evidencing these disorders and providing the clinicians with the necessary information.
肌腱的冲突、弹响和不稳定很常见，超声（US）是诊断这些情况的首选方法，这得益于在成像研究期间能够进行动态操作。肌腱与骨结构、其他肌腱、支持带或滑车之间可能发生冲突。弹响可能由于支持带破裂引起的不稳定、增厚的支持带与骨隆起之间的冲突或肌腱位置异常所致。不稳定可能由于支持带将肌腱保持在骨沟内的能力不足或无法固定附着于骨的肌腱所致。诊断肌腱冲突、弹响和不稳定的技术要求很高，因为它需要对超声表现和动态操作有深入了解。然而，目前通过动态操作完成的超声检查是诊断这些疾病并为临床医生提供必要信息的首选检查方法。
