This Paper Presented a simple method for measuring wedge Angle between end-faces of crystal bar used in microwave delay lipe.

In bar rolling process, the technical conditions of roughing may change and make camber occurred, for example, different temperature at both bar side, bar wedge and off-center in biting.

Removal of the talocalcaneal bar with wedge osteotomy is easy to operate may preserve the function of the joint, and seems to be a better method for treatment of talocalcaneal bridge.
