An SM portal was established 1 cm medial to the acromion and 1 cm posterior to the clavicle, and a 5.5\u2010mm burr sheath was oriented toward the acromioclavicular joint. The skin and trapezius were resected, the supraspinatus was retracted, and the suprascapular nerve was identified. The distance between the sheath and the nerve was measured by 2 independent observers with calipers. A safe distance was defined as 10 mm.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The measured distances between the nerve and burr ranged from 18.5 to 35.7 mm, with a mean of 24.2 \u00b1 5 mm.
