膝关节

Today, in the foreign intelligent artificial leg, the executive mechanism which controls the bent and stretch"s movement of knuckle and the pendular movement of calf is a single air cylinder. In the air cylinder, there is a throttle, the cylinder"s damp can be adjusted by controlling the opening of the throttle valve, when the air cylinders damp changes, the pendular speed of calf will change too.

METHODS: Puncture with the needle retaining in the cavity of knee of normal adult corpse without effusion or pneumatosis was performed, and 1, 5, 10, 15, 20, 30, 40 mL contrast-medium was injected into the cavity. Coronal section, vertical plane and transect were scanned with T2WI, 4 mm thickness and 1 mm interval by MRI.

对10件无积液、积气、结构正常的成人尸体膝关节腔内穿刺留针，通过穿刺针向关节腔内依次注入1，5，10，15，20，30，40 mL对比剂，分别于每次注射后行冠状面、矢状面、横断面T2WI，厚度4 mm，间距1 mm，MRI扫描。
