Material and Methods:
The paper is based on academic literature and scientific publications, which are available in PubMed database. After evaluation of article’s abstracts, articles were selected and analysed with the references citated.

Conclusions:
There are different methods of radiological diagnostics of Kienbock disease. MRI scans and diagnostic arthroscopy appear to be the most detailed techniques, but X-ray scan should be ordered as primary radiological examination during diagnostic process.
