Standard 3\u00a0\u00d7 14 mm suture anchors were placed in the glenoid rim (1 o\u2019clock, 11 o\u2019clock, and 10 o\u2019clock positions for the right shoulder). The suprascapular nerve was dissected. When glenoid perforation occurred, the distance from the anchor tip to the suprascapular nerve, the distance from the glenoid rim to the suprascapular nerve, and the drill\u2010hole depth at each entry site were recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All far\u2010posterior anchors perforated the glenoid rim when using the anterosuperior or rotator interval portal.
