Localisation and injection of the sinus tarsi can be challenging, particularly for the less experienced musculoskeletal sonographer/practitioner. The inferior extensor retinaculum arises from the sinus tarsi in the form of three roots (medial, intermediate and lateral) which are collectively termed the frondiform ligament. This is readily identified on ultrasound and can be used as a reference point to aid the safe delivery of injectate material into the sinus tarsi. This article describes the technique and its anatomical basis.
跗骨窦的定位和注射具有一定挑战性，对于经验较少的肌肉骨骼超声医师/从业者来说尤其如此。下伸肌支持带以三个根（内侧根、中间根和外侧根）的形式发自跗骨窦，这三根根统称为镰状韧带。在超声下很容易识别，可以用作将注射材料安全注入跗骨窦的参考点。本文介绍了该技术及其解剖学基础。
