Medical device for measuring the angle of a joint, e.g. the knee by attachment, in a highly reproducible manner, of upper and lower bars hinged at the middle to bones on either side of the joint

摘要

Device comprises two bars (3, 8) with attachment elements (1, 11) for positioning the bars at fixed anatomical points on the bones. So that the device can be attached to bones of differing dimensions one or both of the attachment elements can slide up and down its bar.
