Abstract

Goals:Although Caldani´s ligament or medial coraco-clavicular ligament (MCCL) has been anatomically studied, we have not found any publication regarding its identification in image studies. The aim of this research it to present an original technique to locate the MCCL on magnetic resonance imaging (MRI), as well as to describe the pertinent findings.Materials and Methods Seven volunteer patients without any known shoulder pathology were studied by means of this original protocol. A PHILLIPS INGENIA 1.5 Tesla MRI equipment was used, Magnetic field intensity 1,5.Gantry diameter: 70cm, It featured an 8-Channel coil for shoulder study. The sequences to locate the ligament were performed in three planes. The length and thickness of the MCCL were measured.Results The MCCL was observed in all cases. It presented a similar arrangement as described in previous anatomical description consulted. The 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.ConclusionThe MCCL can be observed in MR images utilizing this original procedure. The ability to display the MCCL ligament in MRI allows for future investigations on its possible role in both thoracic outlet syndrome and traumatic acromioclavicular dislocations, especially the Rockwood type V.
