Three-plane kinesiology of hindfoot instability was studied after lesions to the ligamentous structures in the sinus and canalis tarsi in 20 amputation specimens. Neither a lesion of the cervical ligament nor of the interosseous talocalcaneal ligament resulted in an increase in the total range of movements above 2.6 degrees in any of the three planes. However, the percentage increase in the total range of movements after cutting of the ligaments was generally largest in the talocalcaneal joint compared to the increase in the total hindfoot joint complex. The largest percentage increase (43%) in the talocalcaneal joint occurred at dorsiflexion after cutting the interosseous talocalcaneal ligament. The demonstrated minor instability after experimental lesions of the ligamentous structures in the sinus and canalis tarsi may have a clinical identity in the sinus tarsi syndrome. Patients with that syndrome rarely present an objective hindfoot instability, although a major complaint is a feeling of hindfoot instability.
在20个截肢标本中，研究了跗窦和跗管韧带结构损伤后后足不稳的三平面运动学。切断颈韧带或距跟骨间韧带，在三个平面中的任何一个平面上，总运动范围增加均未超过2.6度。然而，与整个后足关节复合体的增加相比，切断韧带后总运动范围的百分比增加在距跟关节中通常最大。切断距跟骨间韧带后，距跟关节背屈时总运动范围增加的百分比最大（43%）。跗窦和跗管韧带结构实验性损伤后表现出的轻微不稳，在跗窦综合征中可能具有临床特征。患有该综合征的患者很少出现客观的后足不稳，尽管主要症状是后足不稳感。
