Inclusion criteria were presence of an HSL, &lt; 25% glenoid bone loss, bilateral 3D\u2010CT, and arthroscopically recorded bone loss measurements. Records for patients with chronic dislocations or prior operations were excluded. Calculations by 3D\u2010CT and arthroscopy were performed as follows: Hill\u2010Sachs interval (HSI) was the distance from rotator cuff insertion to medial edge of the HSL; GT was 83% of the normal glenoid width minus any glenoid defect; on\u2010track was HSI less than GT; off\u2010track was HSI greater than GT.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Sixteen shoulders with HSL status determined as on\u2010 or off\u2010track demonstrated agreement between the 2 methods in 10 of 16 cases (63%, Cohen's \u03ba\u00a0= 0.16). All 6 cases with disagreement were calculated as on\u2010track by 3D\u2010CT and off\u2010track by arthroscopic measurement. The GT was larger as determined by 3D\u2010CT measurement (22 \u00b1 1\u00a0mm [21\u201024]) compared with arthroscopy (18 \u00b1 1\u00a0mm [17\u201020],\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .002).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Preoperative 3D\u2010CT showed slight agreement compared with intraoperative arthroscopic measurements in classifying HSL as on\u2010track versus off\u2010track in the GT paradigm; larger GT size by 3D\u2010CT versus arthroscopy accounted for all discrepancies. Determination of off\u2010track status based on preoperative 3D\u2010CT versus determination with the arthroscopic method would result in fewer HSLs treated with remplissage if the GT treatment paradigm were followed. Surgeons using the GT paradigm to determine treatment of HSL by remplissage should recognize the potential for discordance between arthroscopic and radiographic measurements.<\/jats:p>\n
