GHJ Anatomy & Pathoanatomy

Explore both passive and dynamic stabilisers of the glenohumeral joint — boney stability, the capsuloligamentous complex, and the rotator cuff — through a clinical lens tied directly to patient presentation.

I attended the shoulder level 2 course on the weekend. I thought it was a fantastic course and really appreciated the in depth analysis and evidenced based approach to treatment that both Lyn and Simon presented. It makes you reflect on your own case load, past and present, and realise some of the areas I can really improve on.

Thanks so much! You wouldn’t believe the patient that walked in today. A failed bicep tenodesis followed up with a MUA and EUA/washout for suspected infection, with a unrepaired partial Subscap tear left (and still causing pain)...and ... you guessed it a shoulder sitting so low she get nTOS signs into the ulnar distribution of the hand if she relaxes it by her side. At lease I know where to start now!

Thank you so much for delivering the course over the weekend. Found it fantastic and especially after having two rotator cuff repairs myself, I now realise where I can improve my own and patients' rehabilitation.
