ANATOMICAL ANALYSIS OF THE COSTOCLAVICULAR LIGAMENT'S ATTACHMENT TO THE DRY HUMAN CLAVICLE

Background: The sternoclavicular region's costoclavicular ligament is important for pectoral girdle movements and strength delivery. The sternoclavicular joint is stabilized by the costoclavicular ligament. This ligament extends from the lower surface of the medial portion of the clavicle shaft to the first costal cartilage and the adjoining portion of the first rib.
Aim: The present study was undertaken for morphological evaluation of rhomboid impression or costoclavicular ligament were observed for the following features: a) Impression: Rhomboid impression present or absent. b) Pattern of impression: Flat and smooth (FS), flat and rough (FR), elevated and rough (ER), depressed and rough (DR) and no impression.
Methodology: The rhomboid impression morphology and the location of the costoclavicular ligament's attachment to the clavicle were studied using bones from our anatomy department. A total of 80 clavicle bones were studied, out of which 40 were of right side and 40 were of left side. The various patterns of the impression were observed.
Results: In the present study a total of 80 dry clavicle bones were studied, out of which 40 were right sided clavicle and 40 were left sided. Table 1 represents the status of rhomboid impression on the clavicle bones. A total of 66 clavicle bones had rhomboid impression, 33 were right sided and 31 were left sided. Rhomboid impression was absent in 14 clavicle bones. Table 2 presents various type of impressions on clavicle bones, Impression was seen in 66 clavicle bones, out of which 17.5% had flat and rough impression, 18.75% had flat and smooth impression, 28.75% had elevated and rough impression, 15% had depressed and rough impression. The most common type of impression found to be elevated and rough.
Conclusion: The rhomboid impressions, most prevalent morphological pattern is raised and rough. A rhomboid fossa is a highly helpful tool for figuring out someone's age who is unknown. This fossa is essential to the decision of what sex to have. Understanding the costoclavicular impression region is useful from a clinical perspective for orthopedic, radiological, forensic, and anthropological perspectives.
