Essays, videos & faculty notes

Education is part of the practice.

Dr Coory teaches at international shoulder fellowship courses, mentors visiting orthopaedic fellows in Australia, and contributes to research at the University of the Sunshine Coast. Insights is where that teaching work appears in writing.

How a CT scan becomes a shoulder replacement: inside Mako planning

The robotic shoulder replacement is not the operation. The plan is the operation. The robot is the instrument that executes the plan. A deep-dive on how a CT becomes a surgical plan.

The biology of rotator cuff repair: why technique has hit a ceiling

Two decades of cuff repair has been about technique. The ceiling we are bumping against now is the biology of the tendon being repaired. Essay paired with the YouTube long-form video.

The Rotator Cuff Healing Index — and what we do when biology is against us

The ROHI is a six-parameter score (Kwon 2019) that predicts which cuff repairs are at risk of not healing. Embedded calculator, plus the patient-level, surgical and post-operative biological-augmentation strategies that change the odds.

Shoulder instability: the age-at-first-dislocation rule

If you are under 25 and dislocate your shoulder once, the chance of doing it again is over 80%. The Bankart-vs-Latarjet decision, the bone-loss threshold, and the new allograft technique.

Remplissage in shoulder instability — the missing middle between Bankart and Latarjet

Patrick Denard, Stephen Burkhart and Alexandre Lädermann have argued for almost a decade that remplissage is dramatically underused. The glenoid-track concept, the MacDonald RCT, and the modern decision algorithm for off-track Hill-Sachs lesions with subcritical bone loss.

Why won’t my shoulder move? — the frozen shoulder in plain English

The frozen shoulder is self-limiting but takes 18–24 months. The treatment decisions along the way matter more than most patients are told. What injection is for, what hydrodilatation is for, and when arthroscopic release earns its place.

On the shoulder that was "too complex"

Patients are sometimes referred to me after being told their case is too complex for local management. Those referrals are not a problem. They are the practice.

What Insights is for

Education and training, written down.

The practice has a teaching responsibility. Dr Coory contributes faculty time at international fellowship courses, mentors visiting orthopaedic fellows through the Bateman Orthopaedics fellowship and the Australian Orthopaedic Association network, and participates in research with the University of the Sunshine Coast.

Insights is where that work lives in writing — long-form notes from courses, technique observations, considered patient-education essays, and updates from the research network. Three commitments shape what appears here:

  • Specific over general. Every post addresses one technique, one question, or one teaching point. Not a roundup of clinical news.
  • Honest about uncertainty. Where the evidence is thin or the field is moving, the post says so. Where there is a defensible position, the post takes it.
  • Permanent and citeable. Insights lives here on Dr Coory's domain — not on a social platform that controls what stays visible — so the work is searchable, citeable, and accessible long after the original conversation.
