Basic Science-Anatomy and Biomechanics

The humerus is the largest bone of upper extremity. The proximal humerus is composed of the humeral head, the greater and lesser tuberosities, the anatomic and surgical necks of the humerus. The humeral head is the most proximal, ball-like region of the humerus that is retroverted (28 to 40 degrees) and articulates with the glenoid […]

Portals-Anterior Instability

Two anterior portals (superior and inferior) are established using an “outside-in” technique with a spinal needle. These portals function as utility portals for instrument passage, glenoid preparation, suture management, and knot tying. It is important to separate these anterior cannulas widely so cannula crowding in the joint is not a problem.

The second cannula is […]

Scapula

The scapula is a flat, triangular-shaped bone that serves as the articulating surface for the head of the humerus as well as provides areas for 17 muscle attachments. With the arm at the side, the scapula overlaps the dorsal surfaces of the second to seventh ribs. It has three prominent projections: the spine, the coracoid […]

Glenoid Labrum Tears

Glenoid labrum tears The glenoid labrum is a fibrocartilage rim surrounding the articular surface of the glenoid cavity (the socket of the shoulder joint). The labrum contributes to stability by increasing the depth of the glenoid socket. The loss of the glenoid labrum decreases the depth of the socket by 50% in either direction. A […]
