Editorial Commentary: Science Bearing Fruit: Can the Inverted Pear Be Quantified?

It has been reported and verified that anterior glenoid bone loss can lead to increased instability of the glenohumeral joint. Many authors have tried to quantify glenoid bone loss in recurrent instability of the glenohumeral joint. Techniques have included radiographic, magnetic resonance imaging, computed tomography (CT), 3-dimensional CT, and arthroscopic visualization. A 3-dimensional CT scan using the perfect circle technique, the Pico technique, has become a technique of choice for many authors. However, some have applied this technique using only the uninvolved shoulder. This practice is questionable, and comparison to the uninvolved shoulder is recommended.
