1、关于踝关节lecture第一页，讲稿共三十一页哦Midtarsal joint跗关节跗关节 between calcaneus and cuboid on lateral side外侧为跟骨和骰骨之外侧为跟骨和骰骨之间间 between talus and navicular on the medial side内侧为距骨和舟内侧为距骨和舟骨之间骨之间Talocrural joint踝关节踝关节 inferior tibiofibular jnt.下胫下胫腓关节腓关节 tibiotalar jnt.胫距关节胫距关节Subtalar joint距下关节距下关节 aka talocalcaneal

3、骨（下胫腓关节）之间，胫骨和距骨之间的关节（胫距关节）This joint is responsible for plantar flexion and dorsiflexion and some abduction/adduction.该关节负责跖屈背屈以及一些外展/内收 The axis of rotation is a line between the two malleoli.沿两踝之间的连线扭转第三页，讲稿共三十一页哦Subtalar Joint距下关节Allows pronation/supination and rotation.可以进行旋前/旋后和扭转The talus art

4、iculates with the calcaneus anteriorly,posteriorly and medially.由距骨与跟骨前、中、后关节面构成The axis of rotation runs diagonally from the posterior,lateral,plantar surface to the anterior,medial,dorsal surface.旋转轴方向为后侧、外侧、足底斜向前侧、内侧、足背。The orientation of this axis makes pronation/supination triplanar with refere

7、 during pronation and externally rotate during supination.距下关节运动的轴向引起胫骨在旋前时内旋，旋后时外旋。Thus,the tibia internally rotates with pronation or knee flexion and externally rotates with supination or knee extension.因此，旋前时胫骨内旋或膝关节屈曲内旋，旋后时胫骨外旋或膝关节伸展。It is important that knee flexion and pronation occur in sync

8、hronization(as well as knee extension and supination).重要的是膝关节屈曲和旋前同时发生（膝关节伸展和旋后也是这样）第六页，讲稿共三十一页哦Midtarsal Joint跗关节Actually consists of two joints:the calcaneocuboid on the lateral side and the talonavicular on the medial side.这两个关节实际组成：外侧的跟骰关节和内侧的距舟关节。During pronation,the axes of these two joints ar

9、e parallel,this unlocks the joint and creates a hypermobile foot that can absorb shock.旋前时这两个关节之间的轴是平行的，未锁死的关节形成过度松弛的足部赖吸收震动During supination the axes are not parallel and this joint becomes locked allowing efficient transmission of forces.旋后时，这两个轴不平行，此关节锁住，有效传递力量。距骨跟骰轴跟骨距舟轴正常旋前第七页，讲稿共三十一页哦Foot Orie
