距下关节是保持足部稳定的枢轴 ,承受并传导人体体重 ,转换下肢的旋转应力 ,协同和辅助踝关节运动 ,支配跗中关节和前足活动 ,因此它是后足的力学中心。功能上主要发挥稳定作用 ,活动度小 ,属微动关节。距下关节的关节囊菲薄 ,主要依靠韧带的力量来维持关节稳定 ,韧带损伤常导 The subtalar joint is the pivot that holds the foot steady, supports and conducts the body weight, converts the rotational stress of the lower extremities, synergizes and assists the ankle movement, and dominates the midbrain joint and forefoot activity. Therefore, it is the mechanics center of the hind foot. Mainly play a stabilizing role in function, activity is small, is a micro-movement joints. Articular capsule from the next joint meager, mainly depends on the strength of ligaments to maintain joint stability, ligament damage often guide
