In pathologic humeri, there is severe distortion of the anatomy, making it more difficult to define the normal neck-shaft angle or the location of the normal articular surface. 在病理狀態(tài)下，肱骨解剖結構可能存在明顯的改變，將使確定其頸干角以及關(guān)節面顯得更為困難。
However, anterior and posterior joint surfaces of the subtalar joint sustained compressive stress, and medium joint surface of subtalar joint received tensile stress. 而距下關(guān)節于足跟著(zhù)地期，前與后關(guān)節面承受壓力，中關(guān)節面則承受張力。
