Coracoclavicular joint, an osteological study with clinical implications: a case report

Paraskevas G, Stavrakas ME, Stoltidou A - Cases J (2009)

Bottom Line: The presence of an anomalous coracoclavicular joint was studied in a human male skeleton aged 73 years old from the Osteology Collection of our Department.We describe the exact morphology of this variation that is occasionally reported as an anatomical or radiological curiosity in the literature (0.55-21%).Consequently, it is vital to apply the appropriate treatment.

ABSTRACT

Introduction: The presence of an anomalous coracoclavicular joint was studied in a human male skeleton aged 73 years old from the Osteology Collection of our Department.

Case presentation: We describe the exact morphology of this variation that is occasionally reported as an anatomical or radiological curiosity in the literature (0.55-21%).

Conclusion: Although coracoclavicular diarthrosis is of no significance other than academic, it is important to recognize this variation and the clinical symptoms that may occur, as it is a cause of shoulder pain and arthritis in this or the adjacent sternoclavicular and acromioclavicular joint. Consequently, it is vital to apply the appropriate treatment.

Mentions: Our material was derived from the Osteological Collection of the Department of Anatomy of Medical Faculty of University of Thessaloniki. On the left clavicle and left scapula of a dried 73-year-old Caucasian male skeleton, two distinct anatomical features were found, in the area of the coracoclavicular syndesmosis. In particular, we came across an abnormal coracoclavicular joint at the left clavicle and left scapula. We noticed the existence of two outgrowths forming two articular facets, one on the coracoid process and the other on the inferior surface of the clavicle, near the conoid tubercle, 5 cm medial to the acromial edge. The noticed clavicular outgrowth was triangular in shape with the base at the clavicle and the apex directed downwards. The outer surface was oblique and smooth and it was in exact apposition with the chondral covered surface of the horizontal portion of the coracoid process. From the medical history of our specimen, there was a report of a diffuse left shoulder pain of unknown cause. The examined left clavicle and scapula didn’t appear any pathologic conditions or congenital abnormalities. The present study was approved by the University Research Ethic Committee. (Figure 1 and Figure 2).
