Morphometric features, variability and clinical significance of coracoclavicular tuberosity

PurposeThe aim of this study was to construct an osteological map of the morphological projection of the coracoclavicular ligament on the clavicle.MethodsIn this study, 93 dry clavicles without age and sex records were used. The attachment sites of the trapezoid and conoid ligaments were examined structurally and formally.ResultsThe attachment sites of the trapezoid ligament were triangular in 9 clavicles, ellipsoidal in 18 clavicles and trapezoidal in 62 clavicles. The anatomical structures of the attachment sites of the trapezoid ligament were as follows: 57 were tuberosities, 12 were tubercles, 11 were lines, and 9 were fovea. The attachments of the conoid ligament on the clavicle were low in 23 clavicles, moderate in 37 clavicles and high in 29 clavicles. The anatomical structure of the attachment sites of the conoid ligament was as follows: 50 were tubercles, 20 were tuberosities, 8 were adhesions, 6 were crests, 3 were impressions, and 2 were spines. The attachments of the conoid ligament on the clavicle were low in 20 clavicles, moderate in 50 clavicles, and high in 19 clavicles. The prevalence of the coracoclavicular joint was 6% in this study.ConclusionIn conclusion, we believe that this study provides guidance for clinicians by revealing the osteological traces of the components of the coracoclavicular ligament or the coracoclavicular joint on the clavicle.
