Positioning and Direction of Rotator Cuff Anchors:
- see rotator cuff repair menu
- Bone Anchor Direction:
- modified convergence technique:
- bone anchors are inserted at anterior aspect of supraspinatus foot print;
- direction of insertion:
- insertion of anchors at a 45 deg angle to the bone surface is recommended;
