Description
This video transcript features a detailed talk by Anmar Al-Shawi focusing on wrist mechanics, specifically the causes and significance of clicking and clunking sounds in the wrist. Al-Shawi explains that clicking is a common occurrence often linked to specific movements, which may or may not cause pain. He delves into the triangular fibrocartilage (TFC), drawing parallels between TFC tears and meniscus injuries, emphasizing that they can be traumatic in younger individuals or degenerative in older ones. Diagnosis involves a combination of clinical history, examination, and imaging techniques, including MRI and wrist arthroscopy to confirm the presence of tears and assess joint condition.
The discussion then transitions to clunking, which is described as a deeper and slower sound associated with abnormal wrist movements. Al-Shawi elucidates the mechanics of wrist joint movements—particularly during ulnar and radial deviation—highlighting the complex interactions within the radiocarpal and midcarpal joints. He presents the anatomy and function of the proximal carpal row and its ligaments, crucial for wrist stability and movement.
Al-Shawi categorizes wrist instabilities into dissociative and non-dissociative types, mentioning the common scapho-lunate ligament instability and its clinical implications. He details various diagnostic tests and treatment options available, ranging from non-invasive therapy to surgical interventions for more severe cases. The presentation concludes with an expression of gratitude towards Al-Shawi's mentor for their influence on his professional development.
