Abstract
Background : The purpose of this study was to define the proximal humerus infraspinatus bare area in a human cadaveric model. Methods : Ten fresh-frozen shoulder specimens were used. A deltopectoral approach was utilized for exposure. Following access to the glenohumeral joint, the bare area width was measured at the upper, middle, and lower limits using an electronic digital caliper. Results : Mean upper, middle, and lower limit widths of the infraspinatus bare area were 5.48 mm, 8.68 mm, and 10.78 mm, respectively. Discussion The infraspinatus bare area broadened as one evaluated the humeral head in a superior to inferior fashion.
