What is the proper positioning of the arm during an SCR graft tensioning?

The correct positioning of the arm during an SCR (superior capsule reconstruction) graft tensioning is critical for achieving optimal surgical outcomes. The appropriate angle of 20-40 degrees of abduction with the humeral head centered allows for a biomechanically favorable position.

This positioning ensures that the tension on the graft is appropriately distributed, which is vital for restoring shoulder stability and function. By having the humeral head centered, it promotes an ideal anatomical relationship within the glenoid and humerus, minimizing the risk of complications and maximizing the efficacy of the reconstruction.

Positioning the arm in this manner ensures that the forces acting on the shoulder joint during movement are aligned correctly with the new graft, promoting healing and functionality. This range also helps to avoid unnecessary stress on the shoulder structures, which is crucial during the tensioning process, ensuring an effective and successful rehabilitation following surgery.
