What is the current recommended arm position in abduction for SCR with a tension-graft?

• A. 10-20 degrees
• B. 20-30 degrees
• C. 30-40 degrees
• D. 0-10 degrees

Answer: (B)

Positioning the arm in about twenty to thirty degrees of abduction provides the graft with the right amount of tension to function like the native superior capsule. This level of abduction centers and stabilizes the humeral head, helping to prevent superior migration while still preserving range of motion. Too little abduction (0–10 degrees) makes the graft lax and less effective at resisting upward slide. Too much abduction (30–40 degrees) can over-tension the graft, limiting external rotation and potentially stressing the fixation or compromising graft integrity. The twenty-to-thirty-degree range therefore offers the best balance for a tension-graft SCR.
