[An X-ray appliance for postoperative control of osteosynthesis with locking plate in patients with distal fracture of the radius].

Purpose: A possible complication in regard to osteosynthetic treatment of a lower radius fracture with a locking plate is perforation of the articular surface by screws or a malpositioned ulnar fragment. In order to create good conditions for a homogeneous, reproducible X-ray picture for post-operative imaging control, an appliance for the production of standardised X-ray views has been devised.
Materials and Methods: The X-ray device was constructed at an angle of 20 degrees to the camera. The arm was positioned on the appliance in the side beam path, in shoulder adduction as well as in the dp-beam in 90 degrees abduction of the shoulder.
Results: Through standardisation of the X-ray technique the appliance it is able to supply comparable and reproducible X-ray images. In practice, the representation of both the joint gap and the bolt in the resulting image could be improved.
Conclusions: Better and comparable picture series can be created by standardisation of the imaging technique using this X-ray device.
