Join Ingrid Griessel as she explains the essential anatomy of the extensor mechanism, clearly showing how a central slip injury, whether from a laceration, PIP joint dislocation or blunt trauma, develops into a boutonniere deformity. Find out why it is so essential to diagnose these injuries correctly, and learn how to do so using Elson’s test. Discover how to clinically reason through different splinting and treatment options.

Mikha Roos shows us how to identify and stage chronic presentations. She explains how and why the therapy approach for chronic central slip injuries is different, emphasising the focus on regaining PIP joint extension while leaving the DIP joint free. She highlights the long therapy time required for these injuries, and explains how to increase adherence by setting realistic expectations.
