Summary: This study was done to learn more about the sternoclavicular joint which hasn’t been explained extensively in current studies. Even for doctors specializing in the pathology of joints and bones, it is hard to decide which treatment to choose. A joint is the place where two bones meet and where movement occurs. Without joints, we wouldn’t be able to move around. The joint we researched was the sternoclavicular joint. This is the joint that connects the clavicula and the sternum. This joint is located more towards the center of our body. However, it’s still considered a part of the shoulder. As in every joint, a lot of things can go wrong. For example, it can get dislocated, broken, or infected. In the UH Gent Department of Orthopaedics, information was collected on patients experiencing issues with this joint between 2015 and 2023. The research aimed to gather more details about these patients to understand the typical individuals encountering these diseases. In total, information about 314 patients was analysed. The patients were categorized into 9 groups of pathology. We found out that degenerative pathology in the sternoclavicular joint occurred most frequently. These patients have symptoms because of wear and tear of the joint. Also, the second most frequent pathology was instability of the joint without a traumatic event. These patients suffer from dislocations when moving the arm. The third most common issue was dislocation because of a traumatic event like falling or being in a car crash. When looking at the age these medical conditions occurred, we saw that degenerative SC pathology mostly affects older women. On the contrary, fractures were most often seen in young to middle-aged men. Osteitis condensans/hyperostosis is a disease that causes swelling in the area of the joint. This was most often seen in women in their thirties. Furthermore, we saw that an injection could help patients suffering from symptoms in this joint. Some patients were operated. Most frequently the operated patients had degenerative disease or instabilities. Fractures however were mostly treated without surgery, for example using physiotherapy, painkillers, or an injection. This study aims to provide useful information for doctors who encounter patients with issues of this joint. However, more studies will be needed to increase understanding of this topic. Social impact: By increasing awareness about pathologies affecting this joint between the sternum and the clavicle, this study will help patients suffering from these illnesses. Doctors will have a better understanding of what to look for in these patients. It sheds light on the characteristics of these patients empowering healthcare professionals to recognize and address sternoclavicular pathology more effectively. This will improve patient care and outcomes. Also, if people want to know more about this topic, they can find helpful information in this study. Lastly, this study hopes to motivate researchers to further discover this interesting topic.
