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

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.
