Supraacetabular fossa (pseudodefect of acetabular cartilage): frequency at MR arthrography and comparison of findings at MR arthrography and arthroscopy.

abstract：:Three groups of apparently normal developmental variants in extremities as they appear on radiographs are presented. In contrast to the widely held view that these are of no clinical significance, these ossicles may, in fact, be responsible for symptoms. The first group consists of ossicles which, from the very onset,...
