摘要:
A method of measuring the relative position of a bone implant within a bone in a patient to detect movement between the implant and bone is provided, wherein one or more radiopaque bone markers have been implanted into the bone through a cannulated implant within the bone and one or more radiopaque implant markers have been implanted into the implant. The method comprises: i) determining a first relative position of the bone marker to the implant marker under a first parameter; and ii) determining a second relative position of the bone marker to the implant marker under a second parameter, wherein a change in the position of the bone marker relative to the implant marker from the first relative position to the second relative position is indicative of movement of either the implant or the bone.

So that on ships a manual transport of munitions containers is possible with security in narrow space conditions from a munitions supply to a gun, the munitions container, as a carrying element includes a band which at one end is permanently connected with the munitions container and which at its other end for an adjustment to a variable and useful for transport free band length is detentably insertable into a several detent positions of the munitions container. The band in the transport position forms a loop which allows for transport on backs. In a rest position, for example in the storage position, the band takes on a position of being integrated into the container.
