The Lateral Elbow Ligaments A Correlative Radiographic Study

Knowledge of the lateral elbow ligaments ’ normal an-atomic relationships to osseous structures, as seen on standard radiographs, can facilitate the interpretation of arthrograms and an understanding of fracture mech-anisms. We dissected fresh cadaveric elbows to iso-late the entire lateral ulnar collateral and annular liga-ments as well as their sites of osseous origin and insertion. We obtained radiographs of each ligament after painting them with a special radiopaque tantalum powder cyanoacrylic preparation. The resulting study allowed radiographic depiction of these important soft tissue structures in relation to the attendant osseous anatomy. Because ligaments are normally radiolucent structures, i
