Description
This presentation, delivered by Renaldi Prasetia from Padjadjaran University in Indonesia, focuses on the topic of multidirectional instability (MDI) of the shoulder. Renaldi begins with an introduction, thanking the organizing committee for the opportunity to present. He describes the complexity of shoulder joints, which allow extensive motion across different planes and depend on a combination of anatomical structures and muscular contractions for stability.
He discusses the importance of the joint capsule and ligaments in maintaining shoulder stability, detailing how they work together to prevent dislocation during movement. In cases where excessive force is applied, he notes that these stabilizing structures may fail, resulting in a condition known as shoulder instability. Renaldi differentiates between shoulder laxity, characterized by an absence of symptoms, and instability, which includes symptomatic signs of joint dysfunction.
Throughout the lecture, various physical examination techniques and testing methods are described, such as the Beighton score for hypermobility assessment and specific tests that indicate the presence of MDI. Renaldi emphasizes the nuances of conservative vs. surgical treatment approaches, advocating for a conservative first-line strategy in cases of MDI unless significant symptoms or imaging findings warrant surgical intervention.
As he progresses, he covers the applications of imaging techniques like magnetic resonance arthrograms (MRAs) in diagnosing structural abnormalities. Renaldi also delves into therapeutic techniques, outlining the principles of rehabilitative exercises aimed at enhancing dynamic stabilization of the shoulder through strengthening and proprioceptive training.
Finally, the presentation transitions to surgical approaches for MDI, comparing traditional open surgery with less invasive arthroscopic techniques, and concludes with a summary of key findings and recommendations for treatment. Renaldi expresses gratitude to the audience for their attention before the video ends.
