[Animal model of humeral joint for shoulder arthroscopy training].
Shoulder arthroscopy used since sixties of the XXth century, becomes now dominating operative technique. Surgeon's skills are most important that's why perfect training model is still needed. Ideal training model for shoulder arthroscopy should combine best possible image of human anatomical structures, good accessibility and low price. Despite of great similarity, animal shoulder joint differs from human one. More spherical shape of animal glenoid gives better support for humeral head. As a result of different shape of glenoid, labrum is significantly less developed, and can actually be clearly seen on dorsal part of the glenoid rim. Glenohumeral ligaments are visible but not as well developed as in human joint.


METHODS
We have used pig shoulder joints, all of the muscles externally surrounding joint capsulewere resected. Classical 30 degrees optical equipment and standard arthroscopy tools were used. Labrum stabilization was achieved using anchors and screws. Cannulas were used only in a few cases, in others, joint access was very easy and did not require one.


RESULTS
Animal shoulder model is useful only in case of arthroscopic practice of instability treatment. Implants can be snapped back after practice.
