AZULAY, Guillermo et al. Identificación del ligamento coracoclavicular medial o de Caldani en imágenes de resonancia magnética: Protocolo original y aplicaciones clínicas. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2017, vol.82, n.1, pp.71-77. ISSN 1852-7434.

Introduction: Although Caldani´s ligament or medial coraco-clavicular ligament has been anatomically studied, we have not found any publication regarding its identification in imaging studies. The aim of this research is to present an original technique to locate the medial coraco-clavicular ligament on magnetic resonance imaging, as well as to describe the pertinent findings. Methods: Seven volunteers without any known shoulder pathology were studied by means of this original protocol. A Philips Ingenia magnetic resonance equipment was used, with a magnetic field intensity of 1,5 T, Gantry diameter: 70 cm, and an 8-channel coil for shoulder study. The sequences to locate the ligament were performed in three planes. Results: This ligament was observed in all cases. Its arrangement was similar to that described in previous anatomical studies. Its origin was at the coracoid process, with an oblique path to reach its insertion at the clavicle. The mean length was 41.14 (range 34-47 mm, standard deviation 4.40). The mean thickness was 2.11 mm (range 1.3-3.2 mm, standard deviation: 0.66). Conclusions: The medial coraco-clavicular ligament can be observed in magnetic resonance images using this original procedure. The ability to display this ligament in magnetic resonance images allows for future investigations on its possible role in both thoracic outlet syndrome and traumatic acromioclavicular dislocations, especially the Rockwood type V.
