What can improve exposure of a subscapularis tear during surgery?

Improving exposure of a subscapularis tear during surgery is crucial for effective repair and optimal outcomes. Internal rotation of the arm significantly enhances visibility and access to the subscapularis tendon located at the front of the shoulder. By rotating the arm inward, the surgical field expands, allowing the surgeon to more easily identify and address the tear.

The other methods, while they might have some impact on the procedure, do not provide the same level of advantages. For instance, positioning the patient face down may limit access to the anterior shoulder, where the subscapularis is located. A straight arthroscope does not necessarily enhance visibility or allow for better access compared to other instruments specifically designed for the shoulder. Lastly, limiting arm mobility could hinder the ability to position the arm for optimal exposure; in fact, perfect mobility and positioning facilitate a better view of the surgical site.
