PURPOSE:To provide a device for osteosynthesis made of polylactate which enables checking for the presence of the device and to see how the device is buried and the learning of the existence of breakage or bending by radiography. CONSTITUTION:This device is made of polylactate in a shape of a pin, a screw or a plate and a bioactive substance 2 having an X-ray contrasting capability is buried into a part or desirably at least one end in the direction of the axis line thereof. This enables the judging of the position and the direction of burying of the device and furthermore, the presence of breakage and bending of the device from the position and the direction of the bioactive substance 2 projected by radiography. |
