Discrimination between plantar fasciitis and partial tears of the plantar fascia can be difficult on ultrasound given laxity of the plantar fascia in the region of its calcaneal insertion and anisotropy. Dynamic assessment with great toe dorsiflexion can improve visualisation of the proximal portion of the plantar fascia on ultrasound, by straightening the plantar fascia due to the windlass mechanism. This article describes the technique and its anatomical basis.
鉴于足底筋膜在跟骨附着区域的松弛和各向异性,在超声检查中区分足底筋膜炎和足底筋膜部分撕裂可能具有挑战性。通过趾背屈进行动态评估,可利用绞盘机制拉直足底筋膜,从而改善超声对足底筋膜近端部分的可视化。本文介绍了该技术及其解剖学基础。
